Alright guys, I'm about to put coilovers on my car and have some questions. My car is multipurpose... Some show, some street, some drag, some autoX. I will be running two sets of springs. My handling/ street set and when I take it to the strip I'll throw on some drag springs.

What I'm looking for is just popular spring combinations... Front and rear! What length and rate do you run for handling? What about drag? Any and all coilover help is needed.

Also feel free to post picks of your ride with COs so we can see the stance!

I'm no drag racer, but I do know that the damping requirements (and spring rates) are hughly different from strip to road coarse. I'd consider swapping out the whole strut assembly; one strut/coil over for strip, one for street/autocross.

I use 475# springs that are 8 inches long. Rears aren't coil over but are 350#.

Rule of thumb--double your coil over rate to get a macphearson rate, that isn't perfect, but close.

As often as this seems to come up, can we just make a big sticky for it? A bunch of us have already answered this question multiple times. The search function is your friend.

I would ask how serious you are with your drag & your autoX? I have turned in quicker lap times than any other mustang that has showed up at the local autocrosses (not that there have been many) & can still stick 650rwhp at the strip. Not the best setup for either but real decent at both. This is without changing springs are much else.

hahaha *some show*

Anyway I am running:

350 c/o front w/koni yellow sport struts
250 c/o rear w/koni yellow sport shocks
MM PHB, PM3L, MM XL SFC's, MM LCA's, 2001 Front control arms w/MM bushings, 4cyl front sway, no rear sway

Rides like a dream and handles even better! Heh it passed the GF test ... so whats that tell ya! I would say the ride is comparable to the new 328 sport package bmw.

Many years ago I autocrossed a car that had a package recomended by MM. H&R springs, bilsteins, MM rear lowers with new ford uppers. The car handled well but snap oversteered very badly when pushed hard.

Impressed with it as a good riding vehicle with decent all around handling , I started at looking at coilover rates to duplicate that setup. I found that coilover springs that were very light compared to what most use would duplicate that wheel rate. I attempted to get assistance from MM regarding a setup with these softer springs but was told that the car be a 0 on a 1-10 scale of handling. Even though they bragged about how well the other car would handle with the same wheel rates. This led me to go my own way on suspension. One of my setups that did quite well overall had 220lb front coilovers, adjustable shocks & struts, don't remember the rear rate & (I hate to even say it) spherical bearings in all ends of the rear arms. This car rode very well, was competitive at local level autocrosses & did not snap oversteer near as bad as that other car that I mentioned. It did well at drag racing as well with shock adjustments. Of course it rolled more than cars with more spring but it did what I asked of it. In the last few years I have moved on to more spring (275lb front), 3-link, etc.

hows the body roll on those spring rates? and how does it handle with no rear sway bar

im gonna try 400 lb springs up front and 300 lb springs in rear
with stock swaybars

PM3L= poor mans 3 link. One rear upper control arm is removed.
With all the MM spec'd, I'd ASSUME MM.
Top shelve parts, and a well pieced together package.

Re-read his post, absorb what he said about the Girl Friend approved ride:eek:

I bought a car that has an adjustable Koni's all around and an Eibach Pro kit, I'm thinking about a coil-over swap but ride quality is high priority. The GF test is one thing, but GF's put up with a lot more than wive's..... :rofl: Also gonna have a 3 and 5 year old in the back, can't be banging them around so I'm trying to do my homework on what will work best...

Sounds like it's time for the Minivan!

Would you take the family for a cruise in a Bimmer 328?

She already has one.... :cool: I'm building the car my way, but I want to be able to take the family somewhere in it, plus I'm 40 next year and don't enjoy being pounded around any more... :) On the Bimmer I have no idea, never driven one....

Mustangs ride better with coil-overs, btw. I went from 1000#/in. conventional front springs to 300#/in. front coil-overs (and later 425s), and the car rides smoother and behaves MUCH nicer on the street over bumps now.

Yes, it is all MM parts for the coil overs front and rear.

The coil overs help a TON! Plus having poly bushings in the front A-arms take away a lot of sloppy *jarring* ride over bumps and let the konis do what they were made to do instead of punishing the rubber.

As for the roll, since removing the rear sway I can still feel the car lean a bit more in the rear through a hard corner then before. The rear setup is still pretty stiff for what I am running (PM3L) and keeps the car pretty neutral.

I am running a 4cyl turbo up front so I have a bit of weight advantage over the 5L setup and that can be seen with the weight distribution. I will be putting it on corner scales this spring to see where I am standing.

I will be testing the suspension out much harder this season, last season I only had a month to play with it and couldn't push her too hard.
