New 15x8 wheel coming!

[nineohfour]

It shouldn't be significantly more, I think he quote me $230 for a custom made 17 x 9.

I "think", not positive, they should be in the $140ish range? Not bad considering all the 15 x 8s available right now are the wrong offset and would need hub rings ($20ish) and spacers ($150-300) and the 949 and UL wheels are all $150-160 for 15 x 8.

So a direct fit for $150ish shipped would still be a good deal.

I'll respond in this thread, or start another, as soon as I get some more info for everyone.

so the 15 x 8 with ET20 would be a direct fit that wouldn't need a spacer to clear the strut? cool! i would assume the fenders would probably still need to be rolled. correct me if im wrong.

Spoke with Paul, Lee was correct, TD does not have a 15 x 8 wheel at the moment.

He said they can do custom made Braid rally wheels, but they are heavy and $400+ each, so not what we are looking for.

I'm going to go with the 15 x 8 TRM wheel.

Does anyone have pictures of the TR motorsport 15x8's on thier car appart from the red car on page 27 of this thread;;;;;;;
Please post em up....

Sorry if I missed it in this massive thread but what is the biggest brakes available from lee that will fit behind the trm 15x8 wheels?

SkinnyVT mentionned in the "other thread" that the Sport kit (300mm x 32mm) only requires a bit of shaving on the calipers.

The street kit seems like it is going to fit no easily. And that will still be a nice upgrade.

The 280mm Street kit will fit many more wheels and is indeed a major improvement over stock brakes. It is strong enough to be tracked with appropriate B compound pads. It will not offer the caliper stiffness of a Superlite, nor the cooling ability of rotors with directional vanes, but it will satisfy the needs of 80% of e30 owners. And those of you who fancy the two-piece rotor look, then RacingBrake offers a pair of Corrado rotors for about $500usd per pair while replacement rings are $360 per pair. Will it bring anything more? Nop. Just looks, and slight weight loss.



BTW Being perhaps the only available 15" x 8" wheel at decent price, I will buy a set for my 2002 racecar.

Lee,

I ran those GENUINE REAL-LIFE FLOATING rotors with my FD RX7 calipers, and I promise you they are worth every penny.

Chris, I would love for you to expand on this a bit. What improvements did you find with the 2 piece rotors over the 1 piece? I looked at them, but it is a pretty serious price increase over the cast rotors. Even the rering cost is a big jump. We PM'd a bit about this at tech, but I never saw a sum up of the improvements.

Thanks!

[Massive Lee]

BTW I have no formal experience with those two-piece rotors. They were suggested to me by a member of the e30tech forum.

All I know is that the replacement rings are $180 each. I have no idea if cooling vanes are straight or directional (should be directional for improved cooling, at that price). The drive-pins for the float seem good, but I don't know what type of floating/play to expect. Please, as you have a set, CBi, share our experience with us. If those two-piece rotors are indeed worth the extra $, then maybe I can deal someting with RacingBakes, or supply my own units. I wonder though if people are ready to pay that much extra.

Let's share our experiences.

Brian, Lee:

I decided to buy a set of the RB floating rotors after I found some information online regarding stock Corrado rotors breaking apart at the track. I was initally shocked at the price of the rotors, but after studying their design, I felt they were worth the money. The drive pin hardware is well-designed, and the rotors have no play or slop. I wasn't crazy about the slots, but they didn't seem to cause any problems other than minor noise and requiring occasional cleaning.

Where the rotors really shined was pedal feel. No matter how hot the brakes got, the pedal always felt the same, which was rock-solid. With a floating rotor, the rotor ring can expand freely in the radial plane without any distortion (which a non-floating rotor CANNOT do), which keeps pad-to-rotor clearance at a minimum, which in turn keeps the brake pedal feel consistent. This was the greatest redeeming quality about the rotors.

I was skeptical about RB as a company, and I had a discussion with Dave Zeckhausen about them. Some of RB's other products seemed kind of gimmicky, and I have read about STi/Evo rotor failures. However, the Corrado rotor is unique, and it is not designed like any of RB's other floating rotors, and after having a set in my hands and examining them, I felt there was little chance of failure by design.

I beat the crap out of those rotors for almost 2 years, and I never had a single problem with them. They held up to heat very well, and seemed to stabilize after developing the initial heat-checking.

I'm not sure the RB floating rotors would appeal to anyone purchasing the Massive "budget" BBK using the Corrado rotor. I think it would be a HUGE waste of money, and the caliper provided with the kit would never stack up to the FD RX7 caliper, in terms of strength (caliper flex). But buyers of the budget kit are looking for a "stage 1" type upgrade for their brakes, and I think it is fine with the 1-piece rotor.

IMO, I think the Massive E30 Race kit with the rotors and hats converted over to floating hardware would be a great setup for a track/race E30, if not overkill. Those huge beefy rotors could take some serious abuse. However, in the final development days of my RX7/Corrado setup, I was totally satisfied with the braking performance and didn't feel a larger rotor was really necessary, and would have been just adding unsprung weight.

Thanks for the explanation Chris, that makes a lot of sense. Did you ever take temp readings of the brake rotors? What pads were you running?

I remember reading about some of the other issues that RB had, which is another reason I wanted some feedback on your experience. So in the 2 years you used the rotors, you didn't have to change the rings (friction surface)?

I'm not sure the RB floating rotors would appeal to anyone purchasing the Massive "budget" BBK using the Corrado rotor.

I'm not going to get into the caliper stiffness issue other than to say Wilwood calipers have their share of both detractors and proponents. For what I will be using the brakes for, I think your statement is correct, in that stepping up to the 2 piece rotors would not be a cost effective step. I'm looking forward to running the final setup I've chosen, all I have to do is get the calipers and it'll be on the car.

Thanks for the insight Chris. Sorry for the hijack, guys.

The TRM fits the Race kit, like I've stated many times and doesn't require "significant" grinding. Fronts need an 8mm spacer to clear the spokes and F/R need a little material removed from the caliper end.

Post a picture so I can see how much material you took off compared to what I took off to clear the TD 1.2's and D-Force LTWs.
