For those wanting the DP4, you'll have to order without calipers and source the DP4's elsewhere.

Will an adjustable proportioning valve be required? I already lock up my fronts well before the rears. I don't do any real racing, but these are cheaper than replacing stock parts, so I'd like to order a set. How will having larger front rotors upset the already strange brake balance (front rotors are smaller than rears with the sport brakes on my 01)

Prop valve is always a good idea, no matter how balanced or imbalanced your system is. Conditions change so no one setting or system config will be 100% perfect for every condition.

As we mentioned on another forum, there are a few very fast track cars running 11" BBK's up front with either our rear BRK using port Brake rotors or just stock 1.8 brakes and the same aggressive pad they might use for front Wilwood caliper. When have a rear kit ready, the advantage will be a significant weight savings but the rotors won't be much larger that current. Brake torque isn't much an issue provided you have the right pads for the job.

Wilwood kit installed
 

This kit will be standard equipment on the SuperMiata.

For those that will inevitably ask, the ducting came from HRP World. Giant zip ties from HD Motorsports.
