Coming winter probably gets somehow busy in my garage....
Somewhere out there, there are stiffer Sport Springs and swaybars by H&R bound to arrive soon and, today I made my mind out (read: learnt to live with the budget they propose), so I will go for a rather dramatic diff shortening .... 4.27 ->5.00 (hillclimb final gear by ///Motorsport)....
This would both limit the Vmax significantly (I do NOT care!
) and give me some extra 17% power on wheels....
EDIT: I forgot... just quite recently swapped a standard to ///Performace intake on my other car (330ix e91).... well, it breathes a lot better now... anyone knows bout anything similar to fit 30i Z4 e89 (EU specs N52B30K - 190kW) ?
