Wheel Fitment
 

I have a 2ks4 that i want to slap some 5x100 rims from the s line TT on there, If I used 12mm spacers I could run them with my stock bolts no problem right?

thats not what a spacer does...a spacer means its puts the wheel 12mm further from the hub. you need hub/wheel adapters to make that work...but i really would not recommend that. the sizing is that size because of reason, you go too small, you loose some strength in there...dont forget, your car makes much more power than a TT.

Yep, what he said ^^. I just put some 2004 S4 rims on my S4 and the wheels were scrappin the caliper. So I bought some 10mm spacers on em it just spaced the wheel farther out so it no longer rubs. Plus it gives the wider more aggresive look.

I couldn t find a wheel adapter to fit .unless you like your wheels sticking out past your fender. i was given a set of porche 5 star twists reps off of a vw bug . was going to be my winter wheels. I still need to get rid of them.
