Between the barrel and the caliper. Plenty of space between the caliper and the spokes, maybe 1/2" or more. I'm back on my stock wheels for the winter though so I can't take a picture any longer unfortunately. None of the big brake kits fit on the 17" RPF1's from what I've been told.

These wheels aren't the lightest in the 17x9" +48 offset (17.5lbs), but they claim they fit the RX-8 and there's a production run planned for Feb 2010. They also look sweet in matte bronze!

If your going with a 17x9...Why not just get the RPF1 that is only 15.9 lbs...Unless your going to get a BBK, then it will fit just fine.
If your looking to get the BBK...it will be hard to find a set of 17's that will fit. Possibly a used set of CE28N's or RE30's will fit. You can find them for good prices if you look around

At the end of the day, are these 6UL benefits worth a 1.5lb weight penalty???
I'm glad to hear you like the RX-8. I've never owned any car for more than 2 years, and I'm currently at that mark in my RX-8. However, I plan to be in this car for at least another 2 years...maybe longer!
At the end of the day, I'm doing research with an open mind and upgrading my car the way I see best. Good luck in your build #2.

The RX-8 has a Torsen, right? Have people complained of it being problematic when on-throttle mid-corner? I assume you'd move to a clutch type?
The SM2 S2000 folks I know seem to prefer the clutch-type, but they're also making a lot more grip, and so getting a lot more roll than we are.
I'd rather have a gear-type of some sort, as it'll move power rather than just limit wheelspin, but the big fat bimmers unload the inside rear wheel too much to make them work.

If I upgraded my lsd, I'd go with an OS Giken (clutch type).

They only had one set in the country. They had the guy from the warehouse send me an e-mail directly with the weight. He confirmed that it was an 18x9 +40 RP03 that he weighed (w/ centercap).

Well, with limited funds (4-5K), I've decided to focus my local STX build on the following:
I'm hoping to do at least the Peru NT in 2010. Beyond that, it'll just be local stuff for me.
- 17x9 +48 6ULR wheels
- 255/40/17 tires (undecided on brand)
- Adjustable swaybars (F&R)
- RB intake
- RB mid-pipe (with 100cpi cat & resonator added)
- Coilovers
- BHR GMC Yukon Ignition kit

Only comment I'll make is that I made my 210 rwhp with a stock intake. Eric Meyers has also said the intake is woth very little.

The world of limited slip differentials is confusing.

Case in point, the CSP Miata folk seem to like the Giken a lot. However, those cars have huge grip and the top drivers are complaining of inside wheel spin using the stock Torsen, and thus see improvement from a clutch LSD. With street tires, the grip is lower and the inside rear wheel should not be unloaded as much as a *SP application. Not to mention the fact that our cars have a wider track, which again should reduce weight transfer.
I personally have no recollection of inside wheel spin problems on my car, but then I may not be driving it fast enough. And, perhaps there are other reasons for a different diff, such as the low-speed understeer problem?

Not expecting big gains, but I wanted to get it out of the way before I get a Cobb AP and a protune. I also plan on adding a header before the protune (minimal gains also), but I'm putting this purchase off for a bit longer.
I should also add that the BHR kit isn't a true STX mod as it's stock class legal. I just didn't get around to doing it until now.

I'll be researching the diff thing some more in 2010. According to an S2000 guy and a CSP Miata guy, they both spoke highly of the OS Giken (over a Kaaz and the stock diff).

True about the alignment. I'm running -2.5/2, with (I think) good temps & even wear.
Yes, the CSP guys like the aftermarket diffs, but again they are running 275 710s on 2000 lb cars. Our cars, in STX trim, have lower peak g's and a wider track, and therefore less weight transfer, which equals more weight on the inside rear wheel at peak g's, and therefore should have less of a problem with inside wheel spin.
At least, that's the theory. Next season, I'll start paying more attention to the car's behavior and see if there is a problem to address.

Very good points George. I'll feel my car out next season and see if I think it needs one as well. I also plan to have a few other drivers try my car (Shawn, possibly Strano, and a few others) and see see if they feel it needs a better diff. However, my main priority in 2010 will be sorting out my suspension (adjuster settings, ride heights, swaybar settings, etc).
I know Karl was having some power-induced oversteer issues in my car at the last NWR event, but I think that was due to the fact that he is not used to the power delivery characteristics of the rotary (and also likely due to some ham-fisted shock tuning on my part at that particular event). I'll ask him to pay closer attention & see what he thinks. As an Evo instructory he's literally autocrossed hundereds of cars, so he should be able to pick up on these sorts of things.
