Hello everyone, I am new to this forum . I just bought a 2001 Mercedes Benz S600 today, and I would like to know what's the best performance upgrade I should do. I'm willing to spend around $5,000 grand on upgrades. My goal is to hit in the 12's quarter mile bracket.

I was told about Renntech performance, what is the best upgrades for me to get, to get my S600 in the 12’s quarter mile for around $5-10g’s in upgrades? My 2001 S600 run 13.9 stock.

Any advice would be greatly appreciated.
Reply ASAP. Thanks!

 

ok for started if you wanted a 12 sec car you should have bought a race car. trust me you dont want to screw with that v12 if stuff happens its very expensive to fix. jut two weekd ago i saw what happen to this kids cls500 that rentech did some upgrades to well lets just say it either droped a valve into the cylinder or the kid floated the valves we couldnt tell because when the rod broke it sawed the motor in half the motor was over 30k that his warrenty didnt cover. so trust me guy drive your car its fast enough.
