- Must buy IMO with caliper purchase
Super glad I picked this up along with my caliper purchase. After the rear calipers were installed, I was able to feel my rear brakes doing their job for once. Install was quick but had to bend stock brake lines ever so slightly to line up with the ports.
- Make those rear brakes do some work...
In a stock configuration, the rear brakes on an NA Miata do almost nothing (except hold the car with the e-brake). I hope you never learn why you want one of these. I was racing my '90 Miata in a World Racing League endurance race at Circuit of the Americas during a torrential downpour. The front wheels would lock up braking into every turn. I had to resort to aggressively engine braking. If I had the proportioning kit, installed at the time, I could have just dialed in more rear brakes, saved my engine, and had faster lap times!
