Bienvenue à toi. =)
I've read ur setup for il y a MPS. Lots of good stuffs right here

i think it have never broke,no? ARP studs <3
MK4 can be find here,but you gotta know that the fuel here is very

quality,you lost around 15-30hp.
A friend of mine got an MK5 GTI, he ran one in france last year, he took one here, both were full stock...he thinks he has lost about 30hp in reunion.
Anyway,there's only one race track,the one you saw in the video,and for the others...street racing or drive in lil pass in the mountain...
You got the choice

Last thing: with all that pieces in your car, did it stayed "street legal" ??? ive seen a supra in japan with about 800hp that was still street legal...until the owner switch the gearbox to a sequential one.
How about car mods in USA?
