Ok im not sure how old this thread is but since im going to tune my 156 gta il just continue here...
So my setup right now is besides from the great standard GTA,
Novitec coilovers adj in height and pressure
BBS ch 18" rims
Tarox discs and pads
Supersprint centre and outlet (box)
BMC CDA
im probobly missing something but then again my questions is about the new items im going for
LSD from autodelta
Chamshafts from CB Performance
Supersprint manifold
Supersprint Cat.
so my first questions is, am i insane? well actually im not..
im willing to spend around £5000 on the car and since sweden dont allow Tüv clearance only i have to stick to items that wont turn me down on my yearly checkup..
So, what im wondering is first of all the LSD how big is the work to get that on? i wont be doing it my self but i would like to know some before i order the items...
since my car needs a set of new timingbelts im going to do the chamshaft change also

but there are 4different ones and im not sure which one is more friendly when it comes in term of tüv approval, i dont want to have to remove them 1 time per year, want them on for "ever"
any thoughts?
i was thinking of a compressor kit / turbo but that will just lead me in to having to remove it all the time and also there arent that many companies in sweden that can and also sell a kit for a AR 156 GTA...
