I recently completed my brake upgrades on my RS. I collected parts over a long period of time, picking and choosing my deals, and did everything at once. My brakes now have awesome pedal feel and stopping power is great, though I haven't really pushed them to the limits yet.
Here's my setup:
- Single Stage Booster from '95 L model
- 1 1/16" bore Master Cylinder (origin unknown)
- ATE Super Blue Fluid
- Stoptech Stainless Steel lines
- WRX front setup (WRX caliper brackets, stock WRX rotors for now)
- Stock rear setup (stock WRX rear rotors, same as RS)
- Axxis Ultimate pads all around
- SpeedBleeders
Let me tell you something about SpeedBleeders. They are worth the small price you pay for them. I had never bled brakes before doing this job, and except for a little help from the wife when priming the master cylinder, I bled the whole system myself in a very short amount of time. And that was a full flush of the old fluid replacing it with the Super Blue. Speed bleeders work. Period.
The RS comes with a 1" bore Master Cylinder stock, but the '99 MC cannot be used with the Single Stage booster because the design is not compatible. I received a 15/16" bore MC with the SS Booster, but opted to use the 1 1/16" bore MC to reduce pedal travel a bit more. I still have the 15/16" MC and will sell it to anyone interested for $35 shipped.
As for the Master cylinder bracket I've read about, I haven't been convinced that it would be worth the money. And with my current setup, I don't even feel that I would need anything else anyway.
