RX 7 turbo brakes

[socorob]

I had a lot of free time today, so I went to the brembo link and found 22mm rotors. These will fit inside the rx7 turbo II calipers. I only looked at 10-11.25 inch diameters. I was looking for what would fit in 15 inch wheels. Now some of these years and models may have only had 1 certain package that had the right rotor, so if anyone is using this, do the proper research before buying anything. I was mainly looking for a rotor to use with the rx7 caliper for a sunbeam alpine brake upgrade. Looks like an 88 Mazda B2600 truck or 85 300 ZX rotor may be the best fit for the way it mounts. Heres what I came up with, the last number is backspacing approximate in inches.
85-91 rx7 2.1
84-89 300zx 1.05
90-97 infiniti g20 1.64
88-00 maxima 1.64
87-91 camry 1.66
85-89 celica 1.66
07+ corolla 1.58
99-04 ford focus 1.34
99-05 fusion 1.34
94-98 mazda 323 1.54
91-97 mx3 1.54
88-84 nissan 240sx 1.64
200sx 1.64
91-94 celica 1.58
87-02 corolla 1.66
87-98 mazda b series .54?
83-86 nissan pickup .39 but the rotor is less than 10"
83-92 nissan 4wd pickup .87

Lots of other cars, hyundais, audi,bmw,vw,mini and volvo use the same thickness rotor, but i was trying to find ones mainstream as possible, with a lot of cars on the road still using them.

Robbie, 84-85 300zx non turbo is used by Datsun Z guys with aluminum adapter plate. Yours would be similar but smaller center hole and dual pattern.

[socorob]

Do te z guys use Mazda calipers or mainly Toyota ones? It looks like all they need is a spacer so 1 hole pattern.

Does Brembo list 24mm rotors? I've been looking for a scalloped 24 that uses a hat. something in the 11-12" range maybe, although 22's would work.

Robbie, How bout a "pic" of those series II Turbo RX7 calipers ? I have pleny of the aluminum 4 pots, but don't know for sure if their Turbo. Thanks, roverman.

Jim,
I saw some hondas and acuras use 23mm rotors, I don't know if that helps any.

This is where I searched for the info. It makes you choose 2 fields, so I picked 22mm and then went thru 4,5,& 6 lug since the bolt pattern doesn't matter for the way I'm planning on mounting them.  I'll probably get an adapter machined like the guy did on www.myturboalpine.com did who is on the sunbeam board.

Robbie,the Z guys luck out with same pattern. They use the Toyota calipers. I would use the spacer/adapter on  the other side of the rotor with the smaller Sunbeam pattern between the rotor pattern.

Art, there are pics of the earlier Turbo II finned calipers and newer smooth aluminum calipers on previous threads. They use the same pads and rebuild kits. If you want performance pads specify the 93-95  newer ones. Here are more pics:

Yep, them be the one's. $7 ea at pic-a-part, 1/2 off days. To re-cap, why don't we use a $30 Wilwood, lightweight, .810" thick rotor + aluminum hat to dissipate heat  ? Thanks, roverman.

[socorob]

because .810 is only 20.5 mm and the mazda needs 22mm. Id go that route if i could find the right rotor, but i dont think wilwood or outtlaw makes any that size.

What about making a spacer shim to fit behind each pad? That would effectively reduce the rotor gap enough to work with the .810 rotor  yet keep the pistons in the correct position in the calipers. I've been thinking about this option so that I could use different calipers on my Midget's .38" rotors. Easier than having the caliper halves machined to narrow them. Still might have to do that for wheel clearance, but that's the plan for now.
