Brake boost.. all I have to say is that for those with 335i's you should try it if you already haven't tried! it'll make you jibber

ok after posting I was thinking.. what if they dont know what brake boost is??
its simple brake boosting is braking while your car is in motion ((braking about half way) WARNING** this will wear out your brake pads REAL QUICKLY), reving your engine at about 4-5k RPM, this is to spool your turbo(s).. once the turbo(s) are fully spooled then you let go of the brake and you take off like a rocket... only turbo'ed cars can brake boost because well.. you get the point... but here is a vid for those that need a visual.
the White STI is the one brake boosting... enjoy! and please be responsible drivers and practice on a safe road that you are familiar with
