I have the Stillen/AP 6 piston BBK and 19" wheels on my Z. I want to go to 18s to increase the selection and decrease the cost of tires. Does anyone know if 18" Enkei RPF1s will fit over the brakes? Or is there anyone in the Phoenix, AZ area that has an RPF1 they'll let me mount to see if it fits? I don't need to drive on the wheel. I'd just bolt it on to see if it clears the caliper.

That's the first thing I did. I don't have an answer yet, so if someone on this board has 18s over their Stillen/AP BBK or has a wheel I can fit maybe I'll get a quicker answer.

I was looking for the same thing myself. Nobody could confirm it before I ordered so I ended up going with different rims that are known to clear BBK's better. If you have the rims already, here is a template you can use.

What 18" wheels did you get and do you have the AP six piston calipers (they're apparently bigger than the 4 piston units, so if your 18s clear the 4 piston calipers, they may still not clear the 6 piston calipers)?

I have the caliper profile that you linked to. Thanks for that info. But, the profile doesn't do me any good without a wheel to try it on. And if I had a wheel to use it on, I wouldn't need the profile because I have the real thing already on my car.

I ended up with Advan RS but I do not have the BBK yet. Template indicates ample room, meaning, 4-5mm. (that's pretty much as good as it gets I hear.)

I posted the template in the hope that others who have an RPF1 unmounted will help you out by taking a minute to print it and cut it. (lets be serious, SOMEBODY does, they just won't help).

Thanks. I appreciate it. I'm really hoping someone here in Phoenix with the RPF1s already on their car will let me see if a wheel fits on my car. My post has only been up a short while, so there's likely still a good chance of that happening.

Probably not.. I have 370Z Akebono sport brakes w/a 14inch rotor and I had to shave the outside of the front calipers in the front. Mind you this set up is only a 4 piston, I currently ride on 18x9 +20 BBS LM's and I have absolutely NO clearance between the back of the rim and along the inside of the barrel. I highly doubt a 6 piston kit will fit.

I would... find someone around town with an 18inch wheel... see if the inner circle of the wheel barrel clears the size of rotor + caliper then you're good to go... because the way i see it, spoke to caliper clearance is an easily solved issue with a small spacer...

Which 18 inch wheel makes a difference. While the OD may be constant at 18", I am told that the ID can vary. Assuming that's true, the caliper may fit under some 18s just fine but not fit at all under others.

From what I had found, the monoblock Volks were the roomiest with Advan 1 piece being close next. Well, in NSX sizes anyway. I doubt that it would be any different in 18's.
