Post Why was my rear end shifting on the line...( / )

Last night at the track, I couldn't keep my rear end from shifting left which was pointing my car to the right.... /
I have new Nittos and BMR LCAs if that helps but I couldn't stall above 1400 without this happening.
It didn't do that last time I was there and I had the same mods. My 60' times went up by a tenth.

if the air was a little better you may have been grabbing just enough extra torque to notice a differnce. some things you can check to make sure it isn't mechanical, 1. rear sway endlinks, if you hurt them it stops holding the car level. 2. hurt shocks, if you hurt eithe rone of them it will allow the car to lean when you load the convertor adn also cause a very crooked launch. 3. if it was just doing it on launch it coudl eb track conditions, a heavy(grippy) track will make the car all sorts of twisted up, just raise your air pressure a bit and take advantage of it.
hope this helps.

later

Check everything that the last guy said and also check while your Nittos are cold that the tire pressure in both of them is the exact same, sometimes a little difference in tire pressure will cause the turn in your car when one wheel grips differently from the other.
