Hi guys, next step in the build is addressing the brakes. 94 that will be mostly street driven but will have the occasional autocross event. Car will be 300+ hp by spring time so I want to make sure i have adequate braking. What big brake kit do you recommend for the front? What pads for the rear? Thanks

 

My .02 cents for autocross would be stock or NB brakes; as I feel during an autocross you don't have enough time to really get the brakes that hot, as in a 20 min. track session. Properly working stock brakes, with good pads, like Porterfield R-4's, and many others work well.

 

No reason for a BBK, you only need bigger brakes if you need the heat shedding abilities which you will not. Good pads and fluid and you're good to go for 2-3 130-60 braking events in short succession , any more than that and you'll need the BBK.

 

If you stay with stock 1.8 calipers, look into Performance Friction Corporation’s compound 11. Direct fit. OG Racing usually has them in stock.

 

OEM 1.8 or sport brakes with a low operating temp pad.

 

BBKs are for track use where you need tons of heat absorption capability. If you were doing that I'd suggest TSE or StopTech.

For a high-dollar autocross build, a "little BBK" can be useful. Lightweight aluminum calipers, rotor-on-hat, but in a stock-sized package to minimize the weight of the brake package.

After owning the StopTech and seeing how they fit i'd say TSE.

 

After reading a lot about braking for NA miatas and the intended applications I think I will be going the sport brake route with good pads.

Application: Mostly Street 250-300hp and Ocassional Autox. No track days.

 

Could you elaborate on this? I'm curious on what exactly is not a good fit.

 

Street/autox: OEM Sport brakes (cheap) or TSE 11.75 w/ straight vanes (lower operating cost and better pedal feel)

Track days (NA or mild turbo, similar pace to SM): TSE 11.75 Dynapro w/ directional vanes

Track days (turbo+race, 4+sec faster than SM): TSE 11.75" Superlite

 

Also after BBK. 2001 VVT, turbocharged 250-300hp. 929 master cylinder. Will mainly do trackdays.
I am between supermiata radial dynapro or trackspeed engineering BBK. I aready have 15x9 6UL wheels for track but would like to use original 16" wheel for driving to track. As i undersand from SM their kit will require spacer for 6UL but no info on stock 16" wheel.
Anyone with similar setups or thoughts?
Best regards.

 

Don't forget the brake proportion valve. The one TSE sells has steel fittings unlike the brass fittings from other vendors.

Andrew posted recently they don't offer the steel fittings anymore due to lack of demand.
