I was wonderign what is avaible for a rear brake upgrade that you can still fit 15 inch drag rims over. I wasnt sure what calipers from other cars or kits or anything like that, that can clear a 15.

Im working on my fronts now 13 or 14 inch rotors and 4 pot wilwood calipers
Give ArizonaPerformance a looksee - they've got a nice rear setup availble that will go with this wilwood fronts.
Maybe the mkiv rear brakes will fit (your wheels)? They fit the mk3 with a little modification, it'll come up in search if interested in this.

Thats what i was looking at was mk4 tt rear calipers do you know any one who has done it?
How does the na MKIV rear brakes compare to the MKIII rear breaks? If they are still an upgrade that may be a choice and they will fit with a set of 15in drag wheels.
Doesn't look like they'll fit 15's because they say they wont fit the stock sawblade thats a 16.
I wonder how they perform compared to stock aswell. seems like a nice cheap easy upgrade if they perform well.

Your best bet would be a brake system designed for NASCAR rims.. They are 15" IIRC, and the way they got better brakes unside the smaller rims was by going with thicker rotors with more vanes to disperse as much heat as possible. (Also larger calipers and pads..)
Wilwood has many options for 12x1.38 heavy rotors with lots of vanes, and either 4 or 6 piston calipers that should fit inside of a 15" drag rim.
However, if your just going to be drag racing, the stock brakes do not suck that much. (They will stop you just fine once or twice in my opinion between cool down periods...) Especially the rear brakes in this condition.
Where I think the front and rear upgrade really plays out is when you use them on a track, autocross or just heavy street running around, and stop from high speeds mulitiple times in say 5 min or less from 140mph or more down to zero or just a few mph... Then the stock setup can't handle the heat dispersion needs, and they fail/fade.
My brakes will not fit 15" rims. (Heck, both rotors are 14" by themselves, and I've yet to find a caliper that mounts up that thin..)
I suppose you could try reverse mount brakes like Buel uses on his front motorcycle wheel, but I've never seen a viable car version of that design. (The rotor is mounted to the wheel, and the caliper is mounted to the hub/fork from inside the rotor.. v/s over the outside of it... ) Would be no fun to change a wheel.. You'd have to pull the caliper first.

Some of the JDM MA70's came with 15" wheels so for a one stop type race (drag) those in good condition would be ample.
