no you are right, I should have said:

both kits can use directional rotors.

The trackspeed kit uses a wilwood rotor, I think:

Any rotor of similar setup will work.

In my 250whp car, the straight veins are sufficient and last a long time. I expect to get 10+ days on rotors, I'm over that already on the first set. I don't think I could get 30-days on a directional rotor making the cost jump not so worth it.

So have we determined any vented rotors for the rear sport brakes? they are 10.8" right?

This is what I have found. The performance difference is small. The straight vanes are good enough by the time you get to an 11.75" size. But if you look at kit price totals directional vane rotors typically cost 3X as much. Best rotors so far I have used have been from Colman racing, but again the performance or longevity difference is nowhere near the replacement cost difference. The thing about the 8 on 7” bolt pattern is there are tons of choices for replacement friction rings, you could even go weight reduced scalloped if you want.

I plan to do this after I triple-dip gild my calipers and get that naked lady airbrushed on my hood.

I actually thought about using scaloped rotors on a dedicated SSM autocross car.

Front caliper temps went from 500*f+ on the sport brakes to 500*f on the Wilwood caliper with the TSE Corrado kit, down to 290*f with the TSE Biggest kit. The only borderline problem I struggle with is rear brake temp using the M-tuned kit. we need ducting in the rears. I will recoup the out-of-pocket on these brakes near mid-season since I'm not longer going through a set of rotors in 3 days (with damatic cracking and breaking) and a set of pads every two days.
When you had the 11" kit were you ducted at all? Are you ducted at all with the 11.75" kit? I seem to remember you are, you had some ugly *** ducts made before TSE came out with their kit...

They are 10.8, although I don't think they're vented. There's a 11" (11.75"?) RX7 rotor and caliper set that can be fab'd to fit, although Cueball1 has it and says "meh", and Sav knows about it and doesn't run it, if that tells you anything. There's also the V8R option that puts wilwoods and vented 11.75" rotors in the back, but that gets rid of the parking brake and there's no rear only option I can find.

Wasn't there a Wilwood caliper with a handbrake solution as well? I thought I've seen it somewhere, but can't recall where exactly.

Bob, do you have any pictures of the initial installation of your mini cooper wilwood kit? I'm 50/50 on it now. If the bolts are all that's to it, I'll probably pull the trigger on it.

I've always had effective ducting, today it's prettier than it was years ago.

Trying not to thread hijack but I think this is a good place to ask....I have the goodwin BBK and was thinking of upgrading to the 6 piston front and moving the 4 piston to the rear but I would need a custom mount for the rear. Is this a bad idea/overkill? There's not much here on the goodwin kit and I only got it because a local guy was selling it out of desperation and basically gave it to me.

Try to convince us that it's NOT a bad idea/overkill, and then we'll tell you why it IS a bad idea/overkill. This is not the forum to just throw out ideas without doing even the slightest modicum of research.

6 piston calipers are completely unnecessary and over kill. If you want to move wilwoods to the back, just buy another set of 4 piston.

I hate to say it, but Sav, TSE, and his black car are a great way to judge your upgrades. If he hasn't done it, it's probably not worth it. I'm not saying the rears wouldn't benefit from wilwoods, and I think Sav is still running sport rears, but 6 pistons in the front is still over kill.

Edit: sav beat me to it.

BTW, I ran 6-pots in the front for a while. I still have the calipers, they're sitting in a box. Small improvement in pedal feel (less than what we found going from 11" to 11.75") and virtually no pad life increase in exchange for a massive increase in pad cost. We'll sell you a BBK with 6-pots (it's a $325 option on top of our full $900 kit), but there's no benefit beyond the bling.

Good-win has a wilwood two piece 10.75" rear rotor and bracket to fit the stock caliper on it.

Not cheap though, comes in at ~600, which is the same price for the no-caliper TSE kit.

Yea, I would have been looking for increased pad life, feel, and bling but if the only real benefit is bling, I'll atleast pay for the shipping if you need the space

The write up I did early in 2005.

http://www.cardomain.com/ride/737924...e-2#7379240007

Since then switched to sport calipers in the rear 1.375" pistons instead of 1.25” huge improvement, the bias valve actually has a usable range of adjustment now.

switched to 1” master cylinder from a 929 slight improvement to modulation feel.

I have looked at willwood rear parking brke calipers they actually make a rear kit for the Mini. The downside is they only have them to fit vented rotors and I think the parking brake hook up is backward to fit right with stock parking brake cables on the Miata.

In my opinion and from experiance with my kit Vented rotors in the rear are unnecessary overkill. Just extra weight.
