I race a 1987 Honda Prelude Si, but I upgraded front brakes (rotors, calipers, knuckle assembly, axle, etc.) to a Accord (1989) LxI....the hub, rotor, brakes are bigger
The wheel on the Prelude would snap off with the hub on the turns, happened 3? times, kinda sad when your car flies off the track and you see your tire passing you....
Now its been great....and more parts available
Rear is stock
I use EBC Yellow pads in the rear, and Hawk Blue in front (EBC Yellow in front wore out too quickly). 4 wheel disc brakes. Stops really well. The car is quite light now, so it really brakes well. I was thinking of getting an adjustable proportioning valve, but everyone that drives the car says the brakes are really well proportioned with stock valve, so I left it alone.
Otherwise, we did a brake booster delete...feels better. A bit of a project, but after lots of calculations, estimations, approximations, and, well,....guesses....we got a master cylinder off a Prius that seemed to work the best....I did not mind just unplugging the booster from the vacuum, but for some, it was a bit too difficult to brake....now its at a happy medium...
anyways, best of luck!
Cheers!
