I had found several references in here to similiar problems. Any ways this is what i am facing right now. I just finished Top gun spacers in front and PRG Deavers mini pack with Bilstein 5125 in back. Now every time i hit onramp or offramps the VDC I believe kicks in and makes that nasty noise from the brake booster area and tries to straighten me out. I also keep getting slip lights on the dash. I put the 10 ply BFG AT KO 285/75 on before the lift with out seing this problem. Did any one else figure out there problem like this or just learned to deal with it. I suppose if I take offramps in a more normal fashion and not like in my S2000 it would help. LOL.
