I got them from Rishie at Auto RND.

I'm not sure if you were talking to me or someone else, but I assume it was me. No, it's going to be more for street use, but I do want to get it on the track someday just for fun probably. I'd rather build one without a sunroof for a track car.

Turbo23- That FC is HOT. I love it.

 

thanks should look better when fenders are painted

 

Speedjunkie. How much clearance is there between the caliper and spokes with the 18x9.5 +45 offset? I'd like to know if they'd work with a BBK. Any chance you can post a pic?

 

It's kinda hard to tell from the pic but the inner part of the spoke is about 3/8" away from the caliper, and the outer part of the spoke is about 1/2" away. So it might be kinda tight. I know the StopTechs are HUGE, most of the caliper is on the outside of the rotor so those would definitely not work. I'd have to see some other kits though to tell on these.

 

I didn't realize that those sizes were available, they look great. I lot of folks should consider these if they're on a bit of a budget.

FWIW, you're not maximizing the rim with those sizes... try 255/35 front, 275/35 rear next time...or maybe you'll want to stay 265/35 for fender clearance. +38 on a 10" rear ought to be TIGHT.... may come down to tire brand.

 

Thanks, I like them too. And they price was great too. They were special order from Japan because of the width of the rear (10 is only normally available in Japan I believe) and they only came out to about $1200.

I did pick these sizes because of fitment. I wasn't sure if it would fit going any larger, and now I'm wishing I had. Rishie suggested I go with anything from 235-255 for the front and 265-285 for the rear. I tried the smallest first to see what it would be like, I'm definitely going wider next time. And maybe a bit thicker on the rear too.

 

Thanks for the pics speedjunkie. The spoke to caliper clearance looks to be an RCH better then my old 17x9 +45 RPF's, which did not fit the StopTech or AP racing template. The ST template wasn't even close. If I remember correctly, the reinforcment rib behind the spokes was the major interferance with the AP template. The 18's may fair better, but I doubt it. Damn.
For tire size, 255's would be perfect on the front. I've run 275's on 9.5" +38 and 10" +42 on the rear of mine. I think you could fit 275's on your rims with just a slight fender roll.

 

^no problem. Yeah I'll have to see what works for tires next time. I might go ahead and make the jump to 245/275 or maybe even 10mm more on each next time. I was going to try for a BBK but decided not too for a couple reasons...one being lack of money, haha. Oh, I already have my fenders rolled too, I did that before I even dropped the car. I used a bat and it turned out pretty well considering, but it's not completely rolled so I'm going to finish with an actual roller.

 

You might want to double check and make sure before making such a claim. I run the 17x8.5 +40's up front, and they clear the Stoptech's just fine. The closest component is the inside of the rim to the outside of the caliper, 18's would given even more room. Spoke clearance isn't much of an issue. I called a guy at Enkei America, emailed him the Stoptech template and he was able to give me an answer right over the phone.

 

YOU might want to double check my size and offset. It's obviously not the same offset as yours. I didn't claim that NO RPF1 will fit, I was referring to MY wheel. I've seen a Stoptech caliper, and considering how little room I have, it WILL NOT fit with my wheel. Just compare your wheel to mine, how deep the center of yours is compared to mine. See the difference? Numbers on paper can say anything, but actually take a look and compare. I didn't have another RPF1 to measure, so how the hell would I know, HAHA.

 

Project Mu or Endless?

 

I did look at your size and offset. Eventhough you're running 5mm more offset, the outside of the rim would still be ~7mm out further than on a 17x8.5 +40. The difference is obviously in the spoke design (17X8.5 +40 comes out and curves back in more) which can be seen in the pictures. I didn't look at the pictures closely, thus, my bad At any rate, it's a great wheel for the money, and Rishie is a good guy to work with.

 

Don't just eyeball it... Stop Tech has a template to download on their website. You print it out actual size and cut it out, and it will tell you exactly. I've got 9" +42's, and they fit by a mile.... but the 8.5" +37.5's I had (Fikse) didn't by about 1 mm.

 

^I'm not even looking at BBKs, so I'm not worried about it. I was just telling him that my wheel isn't exactly the same, so you can tell by looking at and comparing the two that it would work for his and not for mine. I would definitely get the template if I was getting them, I'm not going to leave something as expensive as that to a guess.

All I did was tell Rishie was I was looking for (which was for both front and rear wheels to be concave) and he complied. I agree, he is a great guy to work with, always very helpful. In fact, Michael at Auto RND is the same way, just seems like a good group of guys there. And I also agree it is absolutely a great wheel for the money.

 

Ya doubtful that this will clear Stoptechs BBK at all.

I'm seriously thinking you need to stick with a one piece rotor system like the one Endless offers to make this happen.

However, Racing brake, a new company we distribute for made a BBK for the RPF1 to WORK on the RX8's. I know they can do that for the FD as well but would require a minimum qty. I'll see what that qty is from them.

Most important thing is to keep that rotor hat or bell housing pretty tall to allow that caliper to be offset more inwards to the suspension.

I'm going to compare the Endless systems right now and see if there's a big difference. I know they produce one piece systems.

Thanks, Rishie

 

Just to let you guys know 18/9.5 +45 will clear stoptech BBK..thats what I have..

^Damn for real?! Wow, I'd seen the Stoptechs and how LITTLE room I had with mine with stock brakes, I just didn't think it would work. I stand corrected.
