Wheels for Racing

haha, well I am glad to know I could fit my brakes on a 17x9, but its a different story trying to fit brakes under a 15x9 or 15x8. Its safe to say the RPF1s are not ideal for fitting big brakes on a miata.
I gotta say I love how boost_joose and 2Bit have been marked for negative props.

I will repeat myself: What benefit is there? People run staggered wheels with square tires on AWD cars because you have to run the same tire height on them to keep from frying the center diff, and running a mildly pinched tire on the rear keeps the tire height the same while slightly reducing rear contact patch to improve rotation/ breakaway characteristics.
What benefit would there be in doing this on a RWD car? What tires would you run? Like Curly said, you shouldn't run a 225 on a 7" wheel. You might as well put a 205 on it, because that's all the tire you'll have on the ground.
Sell your staggered wheels on Club Roadster, and buy something with a purpose.

I've owned and abused a bunch of RPF1s myself, and have been in close contact with dozens of autocrossed/ track day-ed sets over the years, and have never, EVER heard of someone cracking one. In fact, the only bent RPF1s I've seen were on a THOROUGHLY wrecked S2000 that went end over end through a gravel trap. You couldn't possibly choose a tougher wheel.
I have absolutely beat the crap out of several sets of Enkie RP-F1 wheels for many, many seasons. So have several friends. I have yet to see one crack. These wheels are awesome. That said, I have had a couple of minor bends and one major, all 100% my fault and the dents were tiny compared to the damage I expected.
I have seen cracked wheels, including 6ULs, Kosei K1's, and others.
We had a Miata rollover at an event due to a cracked wheel breaking. High g-load right-hander with sharp bump @ the apex, outside left-wheel sheared at the spokes. Post roll-over inspection showed that several of that car's wheels had small, hairline cracks.
I run Enkie RP-F1 (15x7"), Enkie PF-01 (15x8"), and 6UL (15x9"). All of these have been good to me. If RP-F1s came in 15x8 and/or 15x9 and allowed for bigger than stock calipers, then that's all I'd run.
What ever you do run...check them closely. The cracks you are looking for are (hopefully!) very small.
You don't want this happening to you...

No "before" picture, but here's an "after".
PS. Hard Dog roll bars freakin' WORK! Driver walked away. First day wearing his HANS.

they look like regular old NB 15x6s. The only other 5 spoke 15x6 was the enkei and the center doesn't look the same at all.
If you remove the center cap from the NB 15x6 (second picture), its pretty obvious. Matter of fact, I got a set sitting in my garage right now lol.
Plus the lip on the enkeis is concave down, while the lip on the broken wheel is concave up (NB style).

+1 for the above being an NB 15x6. I'm running those with SDrives right now for rain. Good to know they go pop...
I've read the easiest way to check for a cracked rim (other than visual inspection or phosphorescent dye) is to pull the tire off and lightly rap the rim with wooden object, like the handle of a hammer. If it rings like a bell, good to go. If it buzzes or clunks (or does anything other than ring) you should probably discontinue use. Any comments or other quick tips?

I am surprised though, I couldn't find a lot of comments about this.
