Roush front sway bar

Just got around to mounting the front sway bar I bought from the roush overstock guy off fleabay on my 99 GT. The thing weighs 21 lbs compared to the 7 lb stock bar that came off the car. He said it was a tubular before I bought it then after I questioned the weight he said it was solid. Hope it improves handling or it'll come right back off.

Just test drove the car and it feels pretty flat. Will see how it does on sticky tires this Sunday.

Wish I would have put this bigger front SWAY BAR on years ago. Car drives more like a gokart. Didn't push as I expected. In fact it was very neutral feeling. I was running on a brand new set of 315 V710s and the car stuck like glue. Ended up winning ESP and paxed 6th over all out of 78.

Uh oh, Han Solo. You revealed a speed secret. I have found the same thing. I have a Eibach 35mm myself and love it. What size is the Roush? I would like to experiment with something bigger, but I haven't found anything.

The Roush bar is 35mm/1-3/8" SOLID. Some still available on that auction site. $125+S&H I think.

You had me by 1/2 second if you wouldn't have hit anything. Of course it's always faster to run over them than to go around them.

Big front sway bars are popular in the Subaru world for auto-xing, too. The Subies are MacPherson strut, and like the Mustang, the stock front suspension geometry isn't the greatest. The thinking seems to be that for auto-x use, it's better to use a big front sway bar because it drastically reduces front roll, which in turn minimizes the impact of the poor camber curve and insufficient caster.

Since you also do track events with your car, Han Solo, I'm interested to see how you feel about the handling balance on track, where you'll obviously see higher speed, longer sweepers with smaller steering angles.

I need to find out if mine is solid. I think it might be but I don't remember.

That was a tough course. I was telling Steven Taylor that I hit more cones this event than I have in the last 3 years total. I really thought that last run was clean, but I was pleasantly surprised!

Escort,

I am running 425lb coilovers. Suspension tuning is very dynamic, and the rules you read online aren't always black and white as defined.

Building a LMSC for the track so the Mustang will just be doing auto-x service I hope.

I don't expect I would feel much different about the effects of the big front bar though. We had a pretty long sweeper in this event and it seemed to give me good feedback on how it would react. The car actually felt a little like it wanted to push in the middle of the sweeper and when I gave it some more gas it turned in better through the final half. I was able to stay right on the cone line through the whole thing. In hindsight I wish I would have pushed it past the limit in several places on an earlier run to see where the breaking point was instead of assuming I could feel it. I probably left a lot of time on the course. New fat V710 tires had a role in the way it feels too.

I had a similar experience when I put on my Steeda front bar, the car became much more neutral where previously it would understeer on entry and mid corner (exits were hopeless because that was when I still had the stock 150,000 mile diff in the car)

I just recently got all the parts I need to go to coil overs up front and at MM's recommendation I went with the equivalent of 800 lb. front springs which will give me a decent bump in my front wheel rate so I was considering going back to the stock bar but I'm not really sure.

I've got the big Steeda front bar and it DOES create understeer in low speed 180* turns, but as Han Solo said, the transitions and body control allow you to better place the car. Unless the course you are running is a bunch of clover leafs, I'd take the big front bar, it really helps against camber loss.

I've been running 3.5* neg. camber and the big 1.375" Steeda bar and it handles well autocrossing.

What wheels are you running 315s on?

21lbs?! I know a certain professional SCCA'er that'd be dry heaving his little self to death if he read that kind of weight gain!

Have any external video after the bar install?

Running the 315s on 17x10.5 cobra r replica wheels with a 5/16 spacer on front. Another big heavy piece that makes up for the weight in performance by putting more meat on the ground. Probably the single best mod I've done.

2k2 it's only a 14 lb gain. I took a 7 lb bar off. Didn't take any pics or video this week.
