Complete adjustable brake proportioning kit
- Product Review (submitted on February 21, 2017):
- 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!
