I want to put brembo callipers on my car, so now i need new rims to have more space. The rims I found are 8j 18inch , et 45. With the 7.5mm spacer its going to be 37et. Is this possible without rolling my fenders?

 

Rear maybe, front no. I would look for better wheels. You are going to be paying more for tires with 18's and but won't be able to take advantage of the wider tire options that 18's give you. On top of that you are still having to run a spacer. It's not worth it.

 

Bola B9 want to put front 8J with ET45.

Is that a question? Or the wheel you are wanting? I am confused.

 

sorry
That"s the wheel I want to buy, should have more clearens for the brembo. So maybe this could work without changing my fenders if I put a 225 tire on the 8J in front?

 

I would still roll the fenders with those.

 

I would like to keep the ET around 50 but i have not a clue what rims could fit? work T5R?

 

You're going to have to figure out which aftermarket BBKs fit like the DC5 Brembos and use a template from one of those kits to estimate whether or not the wheels fit.

Honestly, I think it makes more sense to go for an off the shelf BBK kit instead of trying to retrofit something designed for another car. If you're just doing this for looks get Spoon calipers

 

allready have the brembo, so i'm stuck.

 

Wedssport 25R on the way. I have the 7.5j in 18inch et45 in front, this should work with the brembo's.
Should take 6 weeks to get them here.
