My buddy has been spraying 100-125 shot on his 98 Z28 for almost 60K miles. He's got over 100K on his car and it still runs great.

EDIT: Nevermind, Jeff already posted.

 

what about trannys and rear ends willl the a4 take it for life and will a stock rear with 315 nittos hold up to it ive been thinking about a 100 shot for a while now but my local shop says my 3\4 clutch pack wont hold up for me id use it 0-150 (i dont do tracks i just go out to the backroads)
