The car is not a dedicated drag car, but I do only race in straight lines, 1/4 mile up to 1 mile

The car is a handful under power (1XXX RW), does not like to go straight, plus my tire is rubbing the **** out of rear pass side qtr panel because suspension squats too much. My suspension is set for "road racing" car is lowered some 2", raising car not an option, need it to handle for 1 mile pulls

Here is what I have on the car:

BMR LCA's Non adjustible, poly ends.
BMR APHB -poly ends
SFC's
Koni SA's
Strano Springs
Stock rear sway bar - poly ends.
BMR adj TQ arm.


I have a feeling some of the problems I am hving is the poly mounts move around too much under big TQ, spherical rod ends maybe a better fit for this application. Having adjustible LCA's may also bring help to center the rear. Any input here?

To the "Squatting" of the rear end, I am running 325/50/15s and pass side rear is rubbing very bad, see here:

View Video on FQuick

but this does not happen on the driver's side, this makes me believe the rear/suspension is not equally distributing load, which adds to teh tendency to not go straight. Sway bar may help alot here ?? what about airbag to hold the pass side steady and limit travel????? any thoughts here?

you could start by being outside the waterbox whenever you take off

you could start by noting that I did a burnout and tires were dry and it was not a 1/4 mile run. If tires were wet I would have wrecked.

No, you still had wet tires. Plus, you would have to have some HP before it becomes dangerous with wet tires.

What were you trying to accomplish with that pass? Getting the tires wet and then driving on down the track isnt going to help. You never let the car plant and transfer.

Tiago

dammit guys, stop worrying about the pass... it was just to demonstrate that the tire rubs pretty bad and the suspension squats too easily. The car hardly ever sees teh 1/4.

You made the comment the car doesnt like to go straight. What you did in the video isnt helping at all. Get a real anitroll bar for the rear like a BMR or a Wolfe and crank some power into it.

Tiago

the not going straight part happens on the dry street. But for arguement sake, it dead hooked on that 3rd and 4th gear pull.

I guess what I am trying to describe is "torque steer".

The BMR extreme drag race sway bar looks nice and no welding required but hte Wolfe unit looks better with spherical rod ends...

Any thoughts on my theory that poly bushings are flexing and allowing rear to move under the car?

MADMAN

iTrader: (4)

It could be the poly bushings or it could be the suspension isnt square or it could be you need relocation brackets, or shocks arent set correctly etc. If it dead hooked in 3rd or higher then you need more power up there.

The video shows you have clearance issues with the tires.
You could throw some airbags back there to keep it from squatting and that should help the rubbing.
Road racing and drag racing don't mix.

LOL Madman, Im not looking to break any records, just go down the track or street "safely".

I won't turn up the power until I feel comfortable with the car's handling.

I don't road race with this car, but I intend to do standing mile runs with it, therefore why I need the suspension to be setup that way. 1/4 mile is secondary for now. I just don't want the tire to rub and the only way to control that is to stop the squat. I raised the rear of the car another 1/2", it has about 1.5" to the tire from the fender now, but still squats and rubs hard.

I'll be deffinately starting with a serious rear sway bar. Also looking at airbags.

thanks,

There is a little bit of welding on the bmr install. My 1le bar is all done at less than half your power. Front skinnies help. I like my 185/55/17 M&H's.

coilover kit?

give them a call and explain what you want to do.

also, just widen your fenders with one of those roller things

Tiago

damn I had never seen those coil overs before, hella$$$ but probably nice.

If you need shocks get some AFCOs from Madman.

there's also poly bushing with steel lining: http://www.jegs.com/p/Energy+Suspens...10002/-1/10059





and all metal bushings:

What are the specs on those rear tires and rims?

If my tires were rubing I would NOT be driving hard on them, having a tire blow in a standing mile would suck because it got cut or rubed a few to many times.

If you have adjustable rear shocks I would put them on full stiff and if that helps then I would say there is your issue, if not like others have said maybe a busing or something........

HOWEVER, you do realize that when you launch pretty much a foot out of the water box the tires are wet so they will not hook at all and I am sure that will kick the rear end out since pretty much all RWD cars will d that with wet tires if you ask me.........


You also said it set-up for road racing, but in a later post said you don't road race it......

But like I said, if its rubing, you don't need to be driving it hard untill you fix the issue.

he means "road" racing not track events, the things they do with their car group are 60-130mph events because none of the guys are set up to run quarter mile,
