Car veers right and left when spinning the wheels

I'm not sure if it's the E-diff, or something with the rear suspension, but my car goes anything but straight in 1st and 2nd gear at WOT.

Other cars with open diffs that I've driven would simply light up the lesser loaded rear wheel. My cars with LSD's the rear would break loose predictably and were easily controlled with countersteering, but my 135 literally whips the back end out when the tires break loose (while going straight).

My race car came VERY close to superceding the laws of physics and I could control it even at WOT with both 13" wide Goodyear radial slicks lit up, and it was probably one of THE hardest cars to control in a slide. My 135 scares me.

Maybe what your feeling is the rear subframe bushing being all weak and letting the rear end toe change when under power.

The rear bushings are garbage! Put some M3 bishings in there and you will be so happy. I remember what my car felt like with the OE rear bushings... when I would crack the throttle open(not WOT) just enough to built up some HP, the rear end would squat and wiggle around. IF the road was bumpy you really had no idea which way the rear end you break. Made me write that the rear axle was held in place by simple rubber bands.

Once I had the M3 rear bushings installed.... it transformed my 135i. I think they made the biggest change to the front end of the car. The car now tracked straight(er) and you didn't have to constantly correct while going straight down the road under some sort of power(juice/boost).

Honestly you will be so happy once you get rid of those rear sub frame bushings.

Thanks, I already had the M3 rear subframe bushings installed. I installed the Ohlins R&T coilovers, M3 subframe bushings, and Apex wheels with PSS tires all installed at the same time.

They did make the rear much better, especially in fast, bumpy turns, where the back end didn't waggle around as much.

Glad you posted about this, I've experienced this too. Now I know what I need to do to my suspension lol.
