Z4MC performance upgrades

Not sure if anyone's come across this, but though i'd share on here.

Upgrades include a kw v3 suspension set up which sheds off 2.5 secs off his lap times and a supersprint full exhaust system (including manifold i think) which claims to increase power by 29hp, shedding a further 1.5 secs. That's as much as 4 sec in total!! Sounds interesting, not sure if anyone's had similar improvements..

Exhaust system that gives 29bhp on a NA car? Give me a break.

yeah sound a bit on the high side?????? expect 15bhp with decat or high flow cats to get 30bhp it would need to be remapped.. and some independent tests have shown that remapping has not alway given any more power. a standerd m3 exhaust is a very good unit and very gas flow friedly... a full supersprint system will cost the earth.. if you want bhp get it supercharged or turbo'd if you want massive horse power....600+ AND MUCH MORE ATW HOW BIG ARE YOUR POCKETS.
