Default Eliminatin Torque Steer?

Hey guys.

When I downshift, even when I rev-match best I can, I'm getting a pulling to the right, like only one wheel is turning when the clutch is partially engaged.

Differential problems perhaps?

Tire pressure the same, all around? Same tire type/brand? Same age of tires?

Could be it.

I bought the car off someone else recently, as my previous posts can show. The tires need to be replaced 100% for sure. The front and rear sets match, but they are different brands and styles. I can check the pressures. No clue their age.

Torque steer on deceleration is impossible, and it's predominately a front-wheel-drive issue.

Tire pressures is huge on this car, they have to be bang on, followed by the tires themselves. Once you ensure you have 4 correct matching tires, that aren't 100 years old, and have the correct tire pressures go for another drive and re-check. Secondly, ensure all your calipers are free and no pads are seized in the carriers. Highly unlikely the differential will cause a drag issue since it's a torsen type diff and not a clutch pack diff which can have sticking packs. I would still change out the fluid (as you should on any new to you vehicle) regardless of when the previous owner said they did.

Chek the tire pressure first. Buy a set of decent sport tires.
This is a sports car, its like a Motorcycle. It reacts very sensitive about different tires and pressure.

I've done all the fluids already. Doubt it's the calipers too, I just had new pads and rotors installed, feels fine when driving as well.

I'll get some new tires.

Thanks everyone.

Make sure they are the correct size, too!

Differences in rear tire diameters is what causes this car to do that. That can be caused by tires worn differently, aire pressure differences, or even brand new tires from different manufacturing batches.

Old, worn mismatched tires with unknown pressures, a perfect storm of rear steering vectoring.

New tires, proper size, proper summer compounds (no All Seasons!), From the same batch, same datecode, same air pressure, proper alignment, is going to transform this cars driving experience. You'll be amazed.

Also, any sign of leaking from the shocks at all? Or if you push up and down on each corner, do any of them seem like they have issues (one bouncing a bit more)? I have driven RWD's with one bad shock that would feel as if the rear end was shifting one direction under compression and back the other under rebound.
