why cant i hook??? please help!

Went back to the track tonight after doing Team Z relocated uppers. Made 11 passes. All of which were pretty terrible. 60s between 1.8-2.0. Most of them in the mid 1.8 range. Best time to date was before the uppers, one pass out of eight that went 11.88 @ 116 with a 1.74 60'. The rest of my passes that night were also in the 1.8-1.9 range.

This is with a Hoosier QTP 26x9.5 on a 15. 170 lb hypercoil coil overs in the front, C spring in the back. Strange adjustables front and rear. Tried playing with them and ended up leaving the fronts at full loose and the rears at 3 from full loose. Pinion angle set to -1.3 degrees. Started with tires aired at 16 and lowered them to 13. Skinnies up front. Maximum Motorsports HD weight jacker LCAs.

Launching off two step was an epic fail. Tried 5500, then 5k, then 4500, then 4k, then went all the way down to 3200 and it still just blows first off. Tried launching around 3000r's with out the two step and minimal throttle. Tried sidestepping, tried just dumping and also tried slowly dumping and no luck. Car weighs about 2800lbs with me in it. Nothing too crazy, stock bottom end, trick flow heads, fti cam, track heat intake.

I wish there was someone local who could help me set this thing up or something. Its driving me nuts, my buddy has his two step set to 5k and sidesteps the clutch and dead hooks with eibach drag springs and lakewoods struts and shocks. Track prep is definately part of it but if other people are hooking than what the heck. Im running out of ideas/patience!! lol


I hope Dave Z chimes in here, every time i try to call its usually past normal hours. Somebody school me on ride height/instant center, etc!

Please help!!

It would take me a while to school you on how to set up your suspension. Those rear spri ga are way too stiff. Dave is gonna tell you that those lower control arms are for a dirt track car lol. I used to use Griggs lower control arms that were adjustable and while I could get me dialed in pretty good I swapped to teamz double adjustable lowers that had a fixed height spring cup and then swapped to stock gt springs with 1 coil cut off. My car took very little fine tunning after that. My suggestion is get a set of stock gt springs cut one coil off an try that. You may give some serious thought to getting some new lower control arms also. I got rid of a $500 set of Griggs lower control arms for the teamz lowers and my 60' dropped.

Rear c spring rates are the same as stock I thought just slighter shorter

Your rear springs are WAY too stiff...

Find some stock V8 springs, cut a single coil off and it will have an aswesome ride height and hook better.

I always thought the spring rate was the same, no? I tried looking for used stockers but nothing was available when I had the rear out. I figured the weight jackers would give me ability to adjust ride height to compensate for not having a stock spring and cutting it.

Correct me if I'm wrong, but you don't want the ass end to squat right? So would there be an advantage to a softer spring in the rear? I was under the impression you want the front to come up and transfer but squat is a bad thing

It may be that more weight is needed in the rear end of the car. My car will dead hook when I have the spare and jack in the hatch and I spin without it. I have Team Z adjustable upper and lowers, ABR, 2000 convertible rear springs, 50/50 shocks, 275/60/R15 MT.

C springs are not the same rate. Goto the junk yar and grab a set of v8 rear springs then cut one coil off. It will make a huge difference.

Island drag way. It was Friday night and no track prep basically. Lots of cars running street tires. Lots of ricers front wheel drive rolling water out of the box too. But my buddies lx was cutting 1.6s with antiquated Lakewood's and eibachs

1.6-1.7 should be no problem even on crappy preps...Your springs are killing you.

Explain how weight over the in the trunk gets the rear end to seperate better and hit the tire harder?

How old are the tires ? They can look great but if they are old they get hard and will not hook. and I agree about the springs. A few changes and you should be hooking up in no time.

It's not the size of your shop, it's what comes out of it that counts.

They were new last fall and up until the other night i think they had 7 passes total on them.

This whole spring thing has me even more confused. Everything Ive researched and found says that 84 1/2-93 GT rear springs are 200-300lb rate springs. Which is what the c spring rears are. The fronts are way stiffer yes, but i ditched those and am running a 170lb coilover. Maybe i found bad information or something Im not sure.

You're actual rate may be the same, but the lowering spring are going to ride much stiffer cause their are alot more coils wound up in there. So you rear will not bounce at all, its solid and your shock the rear tires too much. Lowering springs are the worst spring ever for drag racing, way to stiff.

The stock springs will allow the car to sqat some and transfer that energy into the car hooking instead of just shocking them with all the power at once. Having a equal rate on each side and allowing the car to squat just enough to trasnfer that energey into the tires softly will make the car hook harder.

Ever wonder why lowering springs feel like your ride on a flat piece of metal when you hit a bump? Cause they do not give very much, maybe 1" before they bottom out and press back up.

Have you tried adding more pinion angle. 4 link cars like 3-4. With 1 degree when you shock the tires the pinion climbs the ring gear unloading the tires.....Might want to try that. Alot cheaper than buying parts that "might" help your problem.

I agree, I would try more pinion angle -2.5 to -3.

I run eibach lowering springs in the rear of my car and it cuts 1.43 60'

IMO I would put the car on blocks all the way around so you can get underneath it at ride height and set it to 3 and see what happens. If its blowing the tires off on ititial hit tire pressure, track prep, and pinion angle would be the first things to check for me.

Good luck guy, its always a pain watching people 60' with some cheap setup and your blowing the tires off with a decent one.

I would never set my pinion angle at -3 with solid bushings. I run -1.5 and I hook :-) every car I set up with all solid bushings I set to -1.5 and they hook. You have to get the IS, AS and CG correct.

You are correct. The 84 1/2 through 93 factory rear GT and LX Mustang springs are 200/300, which is the same spring rate as the Ford Racing B & C rear springs. The only difference is the B and C rear springs are 1/2" shorter than factory GT and LX rear springs. This info is directly out of the FRPP catalog in the spring section. I use B springs (uncut) front and rear in my car. It hooks hard and consistent. See sig.

Just a quick reply here, haven't read all of this yet. But how old are the tires, what tire pressure are they set it, and how are you doing your burnout?

Since you're running Team Z components, take your measurements with the car on the ground of all the ctrl arm mounting points from the bolt center to the ground. Make sure the car is at weight and sitting normal (ie, the front hasn't been jacked up and sat back down and the front suspension isn't loaded). Let them plot out the suspension and give you a suggestion.

Does the car hook at all on the initial dump of the clutch and then unload the tires, or does it straight up blow the tires as soon as you dump the clutch like its on a wet road? If it hooks initially, then blows tires off, you could try tightening up the rear shocks. 3 is pretty loose. For most track conditions, my rear shocks are on 4-5.

It doesnt feel like it hooks at all. I tried with them at 6 and then went to 5 then 4 then went to 1. it didnt feel like it made too much a difference so i went back up to 3.

at this track they wont let anyone down past the fence for the stands so you can get a good close up video of how the car is acting. the only videos were taken by my really young brother with zero camera skills and an iphone with out it being zoomed. I was really hopin to get some decent footage of how the car reacts at that instant the clutch is coming out so i could further examine it.

I really just gotta call Dave. Ive been working crazy hours lately and never have free time while theyre still open but maybe ill shoot them a ring on my 3 oclock break

What tire pressure and how are you doing your burnout?

With a 5 speed, burnout should be done in 2nd gear to get up some wheel speed.

Method, roll into waterbox, barely spin them over to get them wet, but not so fast as to splash water up in your wheel wells. Pull forward about 6 feet in front of the water box, set line lock, put in 2nd gear, dump the clutch at whatever rpm it takes to get them going. Turn some fairly high rpms until you get some decent smoke, then turn off line lock and let off the gas as you roll out, step on clutch so you don't kill the car when it hooks.

How is your trac lock in the rear? Are you sure you're not getting one wheel peel?

For those tires, my suggestion on tire pressure is gonna be around 12.5-13 psi.

Tires were around 18 for first pass just to try then went to 16 and kept dropping air each pass til it was at 13. I was driving around the water box backing in. Rolling forwards out of the box then second gear burnout. No line lock kit just some heel toe action. Tried just. Cleaning and slight warming to full on melting them til the lettering turned brown.

The rear is an Eaton unit that has never once let me down spins posi every time.

It doesn't seem to lift the front end much
I'm not sure if it doesn't lift cuz it doesn't hook or it doesn't hook cuz it doesn't lift. I can upload some bids but its hard to see what the tires are doing cuz the barrier

Well tried calling dave after work but no answer. Left a message hope to hear back. In the mean time I crawled (best o could) under my car to try and measure and calculate. According to the calc on baselines website my AS value is roughly 99%-110% depending on CG. I wasn't exactly sure how to get a good measurement of it so I kinda eyeballed and tried between 18" and 20.

If this is true then I would think the suspension should be working to hit the tires pretty good but maybe i m not understanding it thoroughly

Where did it say the instant center was at. I'm going to do something here I never do. I'm gonna have you guess at something an try it. I have no idea of your measurements nor your ride height front or rear. I'm gonna take a guess based on some past experiences with relocated uppers and height adjustable lower control Arms. Notice I keep saying guess. I'm gonna kick my self for this as this is not how I like to give help and there is no method behind my guess.

Measure your lower control arm mounting bolts on the front and rear. Make the front bolt 3/8" higher than the rear bolt and make a pass. Raise the rear an 1/8 of an inch at a time and see if you can get it to hook. Your gonna need to reset the pinion angle each time.

Since you have already found te baseline site read the section on the top "how to launch a drag car" I has some useful information. Read it about 5 times and I will start to sink in. That will get you started to understand setting up a suspension.

I just redid it with better measurements. The AS is roughly 115%. The IC length is 35" and the height is 8".
These are rough calculations cuz I'm basing my front and rear weights off a good guessing knowing the car was weighed at 2650. It does sit pretty low. Not sure if its working against me or not. As it is now the front lower control arm bolt is a quarter inch lower than the rear

Having the front bolt that low will never work. Your trying to push up on the rear instead of up on the front. Try getting the front bolt 3/8" higher than the rear.

It may take a few trips to the dragstrip to figure things out. This is usually the case with suspension mods. I always run slower the first time out after a significant suspension mod. On the other hand, this isn't the type of post I like to read after spending nearly $400 on relocated uppers myself.

WOW! I missed this one totally! First Weight Jackers are for dirt track cars and not really recommended for drag cars, that's why you will NEVER see them on a really fast stock suspension drag car. Second All though Island Drag way is very cool, it is not what I would consider good on a test and tune night, especially running a Hoosier tire, which is a great tire on a well prepped track! Third if you have a stick car that weighs 2600 lbs( I'm guessing it was weighed with you in it) a 170 spring is probably to stiff for a drag car(it probably rides good on the street) on a 3300 lbs radial car with 54% on the nose I'd use a 150 lb spring. fourth having your lower control arm pointing down in the front is hurting you more than you know!!! Based on what I know about tire size and stock suspension geometry with the front of your arm 1/4'' lower than the rear with a 26'' tall tire and my uppers it's likely that you don't have 115% AS if you actually had the numbers that you have calculated (35" and 8" with 115% AS) the car would hook on a dirt road (at least for 30-40 feet) too me it seems like a lot of little issues. Springs Front and rear are a little to stiff (If you see a spring that list it's rate 200-300 it's not a spring for drag racing it has a progressive rate which changes as load changes...not good for drag racing traction) a 170 front will provide a good street ride but is to stiff and will defiantly release energy much quicker than what is needed. I would say the biggest problem is the lower control arm being angled down in the front fix that and set your pinion angle to -2.5 and it will start to come around, when you get the time or money to change the spring that will even make a bigger difference!
As far as the measurements on your car, Trace's car has nearly Identical measurements and on a 26X8.5 Hoosier we went really fast. and could hook almost anywhere.
And trust me I've been to Island if you have any flaws in your set up that track will find them!
Good luck...make those changes and you should see good results!

Thanks dave! Found a set of stock springs I had laying around I totally forgot about. Gonna throw them in. Was gonna go to the track tonight but tomorrow is dyno day so I'll take it easy on her tonight, try and make the track Sunday when some real tired cars are running. Originally purchased front coils when I thought the car was heavier but then I weighed it. That weight was with out me, its prob around 2800 with me in it. I will hafta give you a ring for some softer fronts and see where to go from there
