WRX 4 pot have been proven again and again to be worse than stock (or at least, not as balanced/useful)

Just an FYI

Right, which is why I haven't put mine on yet haha.

That's why I was asking if adding the larger Legacy GT rotors would help balance it back out again. Since OP said the Z32 and 4pot were similar, and added the Legacy GT rotors with the Z32 setup, then wouldn't the larger rotors benefit the 4-pots as well?

Force via caliper *BODY* movement vs caliper *PISTON* movement is the difference. Given the same exact piston area, brake force is the exact same (everything else being equal).

The key benefits of fixed calipers are feel, modulation, and pad wear (less tapering as force is applied more evenly across the backing plates).

This is from my race car. Sliding calipers can exert PLENTY of force on the pad:



And so can the piston
Holy Shit..............!!

A little heat??

Yes, assuming you can still use the 4 pots (they would have to fit those brackets he used for the Z32 calipers).

Can't speak for any other products, from personal experience, or for their newer stuff- don't want to bad mouth, just check into it before spending $, which you're doing obviously. But check the vw forums... There are horror stories of their BBK calipers failing. The crossover simply breaking free from the caliper. Complete loss of brakes. Warranty denied. Biggest issue that everyone agreed on was crappy customer service. Perhaps not?

What about a DBA 4000 series for the LGT? Don't they have better cooling vanes? Since we have essentially determined the weight while increased, is very much negligible, (other than in your mind KNOWING it's there :P) but cooling should be better, why not just improve the good qualities you have- since removing mass from the rotor *COULD* remove cooling potential- or maybe offset by better vaning? God knows. My head hurts from this read, but thanks everyone for all the info.

More OT Crap here - - - I should also note- I'm extremely proud of myself for my calculations on my own being determined as what was right. Totally patting myself on the back, you can all hate me for it. re-reading, trying to help my buddy with his celica GT-S not have to pay for a freaking TRD bbk. *SIGH* Told him tires. Auto-x, determine next issue. Hoping to find a vented rear OE brake for it, and then use Avensis front brakes. Same piston, larger pad, larger rotor, so need to balance it out in the back. his back brakes look like my 94 Miatas... Pathetic. Then again, my 94M will stop dam good for what it is. Not... a ton of times. but once or twice :P OH yeah, *facepalm* brakes don't stop car brakes don't stop car *repeating in head*



Not a waste of time, you made this amazing thread.

You guys freaking rock. I love this forum, so much less ... abusive? than others, and I always learn something... and hopefully don't dump it later. Thanks for putting this together OP! Following closely, and if for NOTHING ELSE than cosmetics, this could be worth it to me if it doesn't make the brakes worse, I do drive hard? Spiritidly? (I've definitely cooked the stock pads before...) but when brake upgrade time comes around, might do this instead of the pads/rotors/lines with stock brakes, and just tack on a bit more, and do calipers as well.
I haven't used anything from RacingBrake. I've driven on cars with DBA 1 piece rotors but not the 2 piece setups. The 1 piece is basically like stock from what I could notice.


My brakes (and car) will be up for sale soon. Going back to MR2s.

What niche will an MR2 fill for you? Same one as the BRZ?

MR with torque and HP


And since there will be no car payment, and I'll likely buy a 94 or 95 it won't be a massively depreciating asset (just a regular one) it should be a nice change.

Wile im considering this mod, i realize that the legacy rotors are heavier, i cant for the life of me find project mu rotors for the proper legacy, i cant find dba or hawk rotors either, 294mm not 317mm is there any other rotor that can be used that might have more aftermarket options? As far as pads i can find pmu pads all day for the z32.

Sorry for digging up and old thread, but I'm looking into this for my FI build.

How'd the rear brakes work out? Did the e-brake fit into the legacy rotors ok?

I'm with ya. The 93 86,000 mile car will be going up for sale. Replacing ALL coolant lines, timing belt, water pump, etc as preventative maint first so new owner doesn't need to bother. Also tires and ignition bits.
