I was hoping for mud-wrestling.

If there's a race to be done I pick my home turf in eastern UT:


But, back on-topic as this is tech and not OT.

You need brakes big enough to do the job, and then the smallest wheels you can fit over those brakes. If there's a big gap between your front rotors and the inside of the front wheels, you're not being optimal

Tony just liked this pic, reminded me to comment. Took the wheel off the other day. A rock got caught in between the caliper and inside wheel. Cut the **** out of it all the way around the whole thing. Wheels dipped so that's an easy fix but the caliper I'm . At least you can't see it. I'm just worried about salt in winter time eating the powder coat off entering through the cut.

That's the issue I foresaw with my RPF1's (Thanks Mike) and my AP BBK. They were not touching but a piece of pine straw would catch when I was free spinning the wheels. That's how close mine was. So I'm running a 5mm spacer. It was that or grind down the caliper a little. It puts the wheels out there but I'm ok with it. Hopefully one day I'll run wider fenders.

You go with 18x9.5 +15? Now you have +10?

Yes. I like it. With -3.2 camber also. Not cause of rubbing issues. It clears by miles.

Good. I'll check pics. I want to switch to that wheel instead.

When I ran the brembo 6 pistons, I would get rocks caught between the barrel and the top of the caliper. I had about 1mm clearance after grinding a couple mm off of the ends of the calipers. I actually got black flagged a couple times because the noise could be so loud.

Ok I have a problem with the 18s. Due to the little clearance and heat from brakes, all my wheel weights have fallen off. Anyone have a solution to the problem?

Race bikes we all duck taped them on. Might work. As duck tape heats up its becomes more sticky. If it doesn't work you'll be forced to use the clamp weights that will jack your wheels up.

Then clean your wheels first . Use a 2x4" piece or however big you need to cover a few weights and see if it sticks. If the tape falls off and the weights fall off you have one choice.

Use heat tape to keep the weights on. It is reflective on one side to reject heat. If you are really pimp use the gold tape.
