One thing that came to mind was that if you're upgrading to this kind of stopping power balance has more to do with your cars weight and spring rate than having matched calipers f/r. To properly use a bbk on both ends you would need some certainty about spring and weight transfer. Ergo the numerous combinations to achieve the same braking result .. pedal to piston and all the brake pads in between multiple bias adjustment. Something a twin mc top mount pedal box would be efficient at adjusting. First measure braking temps and decide if the rear is even needed. I'd love to have a huge braking kit all around but if cost vs benefit dictates the front only then that's what I'd do
Yup. I learned the hard way back in the days when I had Wilwood set me up with a custom bbk for my 93 mr2 turbo. Nobody was really running them on mr2s at the time, I think Wilwood said there was maybe 3 other mr2s in the US at the time they knew of with this kit, this was back in 1999. I was running 4 piston dynalites w/ 13"rotors, and 4 piston rear calipers with a separate e brake caliper, using a Rav 4 MC and a manual bias adjuster. I remember trying to fine tune the brakes, running hoosier 245 R comps, I hit the brakes and didnt feel like it was slowing down too much-- well when I look in my rearview there was a cloud of smoke from the rear tires locking up. Just too much brake in the rear, luckily I could play around with the bias. Even after setting it up, those brakes were crappy street driving- just tapping the brakes youd almost slam your head into the windshield,hahahaha. Even then I realized maybe 4 piston rears was too much, even considering that on those cars they have a bit more rear bias than say an evo. My nephew has an mr2, same year. Hes fabbed up a custom brake kit using front Porsche calipers and a rear fiero caliper. His setup is much better balanced than mine was.
If the evo is pretty much still full weight, and your tracking it with R comps and have over 400 whp, then I can see a 6 piston front setup with a large heatsink 14" rotor can help. If your on sticky street tires over 140 tw, with sub 400 hp at the track, then I think a 4 piston setup will do the job. If not maybe consider driving style.
So thats my thought on this, ymmv.

I know you want to stay with Stoptech, BUT... The only front kit I am aware that uses larger than 355 is Alcon Stasis kit. 6 piston front caliper using a 370 (14.5" disk).

I dont know if an 18" wheel would clear that though.
