how to eliminate torque steer


SO FINALLY THINKING ABOUT DOING SUSPENSION. This has been in the back of my mind seeing i am driving around with new struts in my hatch


Im doing my suspension and wondering what bushings i could change to help eliminate sloppy front end.

Clamp/Brace will eliminate torque steer as much as one can worthy investment especially if power has been added.

They don't help with torque steer but they will help firm up the vague, wandering steering feel...

Get the clamp and brace.

Actually if you can a poly bushing for the driver's side of the rack, it will also help. I got one from PowerFlex a few years ago, #7 in your link I think. I even found that GS's 6 point brace helped. Clamp and brace as other's have mentioned made the biggest improvement...next to LSD.

Mike, I surprised that you say poly suspension bushings won't help....I would have thought that they would, even if very slightly. Seems to me that the more you can tighten up the front end, suspension and chassis, the more torque steer you eliminate, but I'm far from being and expert!

Ultimately if you can afford it, a Quaife LSD will virtually eliminate torque steer. Makes my stage 4 Viggen feel almost boring sometimes!!!

Narrow wheels with high offset reduce tramlining and torque steer a lot. Unfortunately, they also look like hell and corner terribly.

Get a steering rack from an earlier build 900. 94 or 95.

Yeah, I was unclear. Good catch.

I should have said they don't help as much as the other things, but they do improve that vague, floaty feel in the stock steering. That itself was more than worth worth the cost and effort of installing them. The only poly bushing that might have an immediate impact on torque steer is the one on the rack itself, but as Tweek suggests, the earlier racks are a thicker diameter and eliminate the need for the bushing at all.

I agree on the LSD suggestion. I've only driven one Viggen with an LSD and not hard enough to really make the LSD assert itself, but everyone I've asked has said it definitely distributes the initial acceleration better and smooths out power delivery..
