Don't mean to get too far off topic, but...

The RA-1's are far better than regular street tires in any of these 3 criteria. However, as BB once said, they wear out like a drunk at a sit down dinner. On the autocross circuit, they are not the fastest tire out there but I'm out to have fun, not be nationally competitive. On the track, they are not the fastest tire out there but I'm out to have fun, not be nationally competitive.
On the street, when they get to about 2/16 of tread rain becomes an issue. I'm there right now after 9 months of use (it would have been sooner is some of my track days weren't in the rain/snow!) so that was one thing prompting me to buy some new "rain tires."I imagine the Pilot Sport Cups are very similar under these criteria but are perhaps faster on the track. They are also much more expensive, so pick your poison I guess. Anyway, the heat cycling from street use will degrade the performance of any R compound tire AFAIK, but after all this time my RA-1's are still far ahead of any regular street tire I've used, including the RE71's.

Sounds like the tire I'll end up using for track/autocross next season. We have very similar outlooks on performance driving...fun, but we're not too serious. I plan to use my current Integrals and P6000s for road work, and swapping wheels/tires for the event. Thanks for the review!

You can also try karting. My FD is my fun street car and occasional track day fun. Nothing beats the rush from wheel to wheel racing like in karting and its cheap. check out ekartingnews.com for some info if interested. Also arrive and drive programs are nice if you gots $$.

I'm think i'd rather just show up and drive Barber's open wheel cars. Blow a motor? who cares, its not my dime. Plus, i think their advanced cars are faster than all but the most extreme track FD's.

Yeah, we have a couple of karting facilities here in Indy. Racers at Union Station was the best, but they went belly-up, and still owes the city money from the failed business. That leaves us with Stephan Johanson, Whiteland Raceway, and Fast Times. I agree that wheel-to-wheel kart racing is a BLAST.

Mine are on US soil!
OK, my RG-Rs are in from Japan and at Wheel Source. These were purchased thanks to following SleepR1 in his search for the Perfect Wheel. I elected to go with the 8.5f, 9.5r setup just as described by SleepR1. They will be shod with Toyo Proxes T1-S.
The wheels took ~ 10 weeks to come from Japan. You gotta be patient on this purchase. I figure to have them in my possession in ~ 1 more week, then I'll put them on. I have a red R1 so I'll post pics to satisfy SleepR1.

Re: BBS RG-R Follow-up
Manny,
I was just looking at the diagram of the new Stop-Tech kit on their website. According to their drawing, the distance from the mounting surface of the rotor hat to the outside of the caliper is 23.25 mm. They recommend an extra 2 mm of clearance, so you'd only need a clearance of 25.25 mm.
Are the brake clearances you listed for the wheels a measurement from the mounting surface of the wheel, to the innermost point of spokes? If so, it may be time to revisit these wheels. Could the Stop tech kit really be that much more compact than the RZs?

This is a follow-up thread to the BBS RG-R thread Rishie started a while ago. Rishie was supposed to follow-up with BBS Japan to see what the brake clearances were for the "Sleeper" fitment, but I have never seen a follow-up.
I've been in contact with Mr. Yamaguchi-san of BBS-Japan. Turns out that the "Sleeper" fitment in the BBS RG-R will not be available for Rx7 Type FD3S because the front brake caliper clearance is not adequate. The 17 x 9, 42-mm offset has brake clearance of 24 mm. Clearly inadequate, since I measured the front brake clearance with my Type RS brakes to need at least 40 mm. My SSR Integral A2s in 17 x 9, 45-mm offset has 45 mm of front brake clearance.
Below is the transcript of Mr. Yamaguchi-san's email replies to my inquiries regarding BBS RG-Rs for Type FD3S Rx7s: [quote]
Dear Mr.Lozano-san,
Thank you for your e-mail.
Sorry, we do not sale to overseas our products.
We announce you conformity size of FD3S/Type RS.
Front&Rear : RG-R722 (17x8.5 Offset+37 Hole5 PCD114.3)
Rear only : RG-R726 (17x9.5 Offset+38 Hole5 PCD114.3)
Brake clearance (Height of a wheel attachment side)
RG-R722 is +43mm.
RG-R726 is +26mm.
(Caution !)
These size is not applied for normal car.
Especially, would be side overhang a frontfender.
Sincerely yours.

Dear Mr. Lozano-san,
Thank you for your e-mail.
We do not have a data that RG-R724(17x9.0 Offset42 Hole 5 PCD114.3)
would be equipped on the RX-7/FD3S.
RG-R724 for TOYOTA/ARISTO's rear only size. (Brake clearance+24mm)
Sincerely yours.

As quoted above the only acceptable BBS RG-R fitment for Rx7 Type FD3S is 17 x 8.5, 37-mm offset part number RGR-722 for front; and 17 x 9.5, 38-mm offset part number RGR-726.
http://www.bbs-japan.co.jp/appli/appli_i09.html
FWIW I calculated the rim lip depths for the above fitments, based on the brake caliper clearance Mr. Yamaguchi provided. 17 x 8.5 fronts will have 41 mm (1.6 inches) rim lip depth; 17 x 9.5 rears will have a massive deep-dish effect of 69 mm (2.7 inches).
Tire Rack doesn't stock 17-inch diameter RG-Rs for FD3S Rx7--only 18s. Tire Rack's fitments are 7.5 and 10 inch wide x 18, fr/rr, respectively.
Wheel Source of Dayton Ohio stocks 17-inch diameter BBS RG-Rs in the widths and offsets needed for Type FD3S Rx7. Here are their prices:
http://www.wheel1.com/shopping/PartD...archtype=wheel
http://www.wheel1.com/shopping/PartD...archtype=wheel
These prices are already discounted from BBS USA's MSRP.
Only DBK, Diamond Black, finish is available from Wheel Source (Dayton OH).
If you want DSK, Diamond Silver, you'll need to order from Wheel Experts. They will not discount for special orders.
http://www.wheelexperts.com/wheelexp...s/bbs/line.asp
Wheel Expert's approximate MSRP for RG-R for FD3S Rx7 is $500 each.
BTW, the weights for RGR-722, 17 x 8.5, 37-mm offset is 8.3 Kg (18.3 lbs); RGR-726, 17 x 9.5, 38-mm offset is 8.1 Kg (17.8 lbs).
PS you can also contact Rishie to order BBS RG-Rs, now that we know what 17-inch size will work. He's been scarce on the forum recently.

Manny asked and now receives.....pictures
Well, one picture anyway. Manny wanted to see the RG-Rs on a red R1, so here you go. This is my Beast with her new shoes. I did have to raise the suspension about a 1/4" to eliminate hard bump rubbing on the outer lip of the front tires.
Manny, there seems to be a LOT of room between the front stock caliper and the insides of the spokes. I didn't measure it, but I think it's about 'two fingers' (as in two fingers of booze in a glass).
In order to get down to the 100K file size limit I had to sacrifice a little picture quality. The edges are a bit fuzzy - the original photo has excellent quality. I am very pleased with the look and feel. My white side stickers don't match up very well with this more steal blue color (double black) - if I'm going to have stickers they now need to be more of the same color (gray or steel). I'll probably pull them off now.

Sweet! Fabulous! Enjoy! Glad you had adjustable suspension. 235/45-17 was pushing the limit with clearance because the tires are slightly taller than stock. I'm glad you're happy with your setup!

Of course it's real....
WTH?
Yes, I took that photo last Saturday after I raised the collars on my coilovers one turn and hand cleaned each wheel, treated the tires, then washed the car, engine bay, and treated the engine bay with C2 protective resin. The only thing I had to do was edit the picture quality down in pixels using my Kodak software because the original is 2MB and you can't upload anything over 100K.
My bank account is certainly lower - they'd better be real.
Toyo Proxes T1's.
Specs:
235/45-17 for BBS RG-R Type 722--8.5 x 17, 37-mm offset fronts; 265/40-17 for BBS RG-R Type 726--9.5 x 17, 38-mm offset rears
I'm not Amur - no photochoping for me. Manny helped me pick these out after a year of hunting around, and asked me to supply photos once they came in (he had a couple of threads on these wheels over the last year).

Beast, take Peter's comment as a compliment. Your car looks so good, it almost looks "too good", like the pic was forged LOL 
The setup looks great, and the BBS RG-Rs are light to boot Enjoy, Eric! FWIW, I copied the pic, and added it to my FD wheel pics archives LOL

I got confirmation back from Stop Tech, the brakes only need 25 mm or so clearance.

Oops...I'm giving away free advice again. I'm never going to collect enough money to buy those new SSR GT2s/P-Zeros the way I'm going--dammit!
Good luck, Peter!

So, next stop (no pun intended) is brakes....
Yeah, now that I've got the wheels, I'm seriously considering the RZ brakes and rotors for the front and back. I get a pretty generous discount with my Mazdacomp account. Are they a guaranteed fit with this?
As appealing as the other kits are (AP, Brembo, Stoptech, etc.), I'd like to use Mazda components whenever possible. Are they already red in color, or will I have to paint them?
Now I wish I DID have photoshop - I'd love to chop them into the pics I have to see how they'd look. Yummy with a red car, I bet.

Thanks, Manny!
I did a search and came up with the various threads on this. Looks like the way to go is the RS brakes with high-temp red paint. Yummy!
Another grand soon to be spent. I'll never get to my paint at this rate. That picture makes the paint look better than it really is - the roof is very discolored and the fading is spreading to the rear hatch.

According to your specs at the begining of the thread Manny, the 17x9 +42 (or 18x9 +42) would clear the Stop Tech caliper by 3/4 of a millimeter!!
Hope they don't flex!!

Ten year anniversary topic resurrection. So i have been searching, and I'm sure someone will be able to link something simple i overlooked, but I figured i'd ask anyway. I'm looking at the RGR in 17x8 +40 and 17x9 +42 (RG724-DBK and RG720-DBK) I found a member who is running the 17x8 with the 40mm offset on all four corners of his FD. https://www.rx7club.com/ne-sale-want...-tires-923749/
So is there any reason the combo i mentioned would not work on a 94 R2 with stock brakes and suspension? thanks for any help or advice you guys can give.

looks promising. if you scroll down to Mazda the 3rd gen rx7 has a check mark for both the RG720 and the RG724 with a note for the 724 being a rear only application.
