I've noticed the last couple times at the track and during a couple street runs that my car pulls to the right pretty good during WOT. not something i cant control but definitely more than i think it should. it drives perfect and straight as an arrow during normal condition, but during runs i have to keep a steady hold to the left.

front suspension:
- qa1r's with stock springs set at 9 left and 7 right on the street, and usually 4 and 2 at the track.
- no front sway

rear suspension:
- comp shitty 3ways at 50/50, stock springs
- double adjustable rod end lca's
- midwest tunnel mount torque arm, -1 degree pinion angle

tire pressures are good and alignment is perfect (i do alignments pretty much 30 hours outta my week).

car doesnt really have traction issues and hooks up great, just pulls substantially to the right.

any idea where to look?

measure roll out of your slicks. dont take it for granted. check your bushings in the control arms as well.

btw, why do you set your shocks different left to right? an anti roll bar should do that.

Rear tire rollout or the rear diff is not centered to the frame.

i originally thought it was roll out but it does it on my street tires as well. rear rod ends are 2k miles old but ill check them, never ran this kind before, front end was tight last time it was off the ground (less than 100 miles ago). ill also check both pairs of tires to be sure. the rear being centered is pretty close because there is very little clearance with the 28"s

i know its a shitty way to compensate, but it helps, roll bar is coming very soon. you think the lack of roll bar may be part of the problem?

What kind of carrier are you running in the rear ? You might be slipping the clutches, causing the car to dart.

Could be a number of things but from what I know is that shocks can help compensate for not having a drag bar but is not a cure for it. Having 3 ways in the back are not good enough.

Being your a t-56 car like me I have done tons of research and what I have learned is these cars need a drag bar. I use a UMI one and the car is now TIGHT, even with the front bar gone, coupled with SFC's the car stays nice on hard turns even with 15 x 4 skinnies in the front.

Many out there recommend not a 10 way single adj shock but a double adjustible deal and that some major coin. I have managed to scrape enough together for the drag bar, TQ arm relocation kit, 10 way QA1's with the fronts being R series and rear being the normal F series.

Even with the bar we my stagger 1 click between left and right but def not 2. Also the rears should be harder then fronts.

Have you tried a same setting, like 2/2, not 4/2 or 3/2?

IMO once the drag bar goes on and you get at least a 10 way shock in the back, your going to be dealing with the hard right. You will be able to preload to compensate.

How fast is the car?

Odds are the car is experiencing some body roll and not loading both of the rear tires equally.

Unequal length LCAs?

car runs low-mid 10's at low 130's. new territory for me so im learning as i go

i have been think body roll was the issue, just wanted other opinions

Have you had the car on a alignment rack get it on a 4 wheel alignment rack and check it if the rears off a little thats what it will do just make sure that they set the rear first a I have seen work done where the car is dog tracking and when you let go of the wheel it goes strait down the road but when you nail it they pull to one side or the other ...its just a thought allways start with the basics

Did you check the alignment with the nose up? I'd start there since the front end will probably be extended nearly all the way when you hit it.

car's rolling over cause you need a good dragbar to keep it level it sounds like to me.
You could try a right rear airbag to try and keep the left side of the cars *** from rolling up but at low 10's I don't think the airbag will help much.
Get a dragbar back there, shocks should be same left to right.
You have subframes and a 6 point?
If not if you get a dragbar and hook well you may pop a t top or worse wrinkle a rear fender.

alignment is right, im 100% on that. never goes toe out through out the suspension travel

have subframes, no 6 pt though.

i have weds off so im gonna check the rollout on both pairs of tires then to rule that out

If it's not the slicks I guess you need a big boy Drag Swaybar.

I vote for LCAs being at different lengths. The extra torque you are making now with the turbo might have caused the problem to come to light.

^ what he said... you need to square up the rear in the car like this:




And if that doesn't completely cure it, you need a dragbar...

You are correct that the car needs to be checked for square. Just dont ever use the ball joints on the front. Most cars have stagger in the front.

will checking the thrust angle on my alignment rack work for making sure the car is square?

you have a truetrac? mine started making scary right turns,, love my spool sense.


you can square it with a plumb bob off points to the ground.
