So while I am waiting to get the stuff together for my engine build I have been looking at my brakes as I need to spend money on something to feed the beast that is my addiction.
currently I have an MSM so sport brakes with the FM upgraded performance friction rotors front and back, porterfield pads and SS lines.
I have been looking at the new Dynapro 6 piston calipers from Goodwin racing to go with either their ver 3 or 4 four wheel kit(two piece rotors all around-those DBA rotors are hot-Kangaroo paw? that's just gotta be awesome right?)

Admittedly getting the 6 piston calipers is more for just bling than anything I suppose and the pad size might limit pad choice a bit, but the 4 piston Wilwoods just look so tiny you know? I cant help but think how good the 6 pistons will look in red with VR paint.
Ok so I am sick. Has anyone else invested in these brakes? Would it be wise to get the wilwood proportioning valve or is the bias ok as it comes?

If you get the Goodwin kit the bias should be great. They are well designed, thought out and created as a package. I've been researching brakes to death and that 6 piston caliper is just pure sex. It's not just bling. You have a whole lot more pad in those, will get longer wear and more even wear. Pads are about the same price as for our cars too. The Dynapro 4 piston doesn't look small the same way the dynalight does though.

Here's a link to a guy's page where he DIY'd his set up by slightly modding the Mini front and civic rear kits.

Ask Brian if a new prop valve is necessary, and do what he says. I think the Dynapro caliper is more rigid than the Dynalite caliper, and the pad is larger. I switched from billet to forged Dynalite calipers on my car and noticed an improved pedal. I have a Panache BBK, 11" 2-piece Wilwood rotors all around. With street pads, the car stops like you won't believe with Hankook RS2 tires. Tires have a significant impact on brake performance. If you don't have the tires to handle a brake system such as any of the Goodwin BBKs, you're wasting your money.

Oh I know tires are the end determination of how fast you can stop.
My street tires are Dunlop star specs and I am debating on R888s or NT01s for track tires
The six piston calipers are probably overkill for how good a driver I really am. I try to be realistic and not be a poser but I simply like how they look relative to the Dynalite calipers. The lack of pad selection is a bit of a concern.
For street I would probably run the BP10s over the wilwood Q pads with the porterfield R4s that I have now on the back.
For track pads with R compounds do people here use the Wilwood H pads? I haven't tracked the car yet but for my ability I thing the R4s in back would be ok. Do lots of folks use the porterfield R4 race pad in back or other pads?

usually people stick to the same brand on all four corners. We'll generally swap compounds between front and back to change the bias to better suit our driving style and the track we're on. I think the most popular pad choice is Carbotech xp8, xp10, and xp12's. I have Porterfield RS4 race pads on all four corners now, however my first track experience with them is not until May 17th. I haven't heard of many others on Porterfield pads.

Read some reviews on the R888 from spec miata drivers, they're toast pretty damn quick. A lot of drivers are mad at the regulation change because their tire budget will have to at least double to be competitive on the R888s.

I was just reading that. Some pretty pissed racers out there. Shame because there was some pretty good hype early on on how it was going to actually SAVE tires.

Yep R888s suck, they are ruining several NASA classes like AI/CMC...guys are moving to ST2 and PT classes so they can run hoosiers and get a REAL contingency...

FWIW I brake -1.2G on the regular Wilwood kit w/Porterfields on R888s..
