I put in a UAS stage 1 front upgrade setup last weekend, and I must say it's great.
Less pedal effort to stop the car and tries to lock the wheels (ABS) if you push harder (265's on 18x10 inch wheels).
I'll find out how good they are on the next track day!
I was running the standard 296mm setup with project mu 500deg pads and they worked okay on the street, but the car was honestly was under braked for the track after a couple of laps.
I'm currently running:
stock 4pot sumitomos with adapters
324mm two piece curved vane slotted rotors
goodridge braided lines
cusco master cylinder brace
project mu 500deg pads
DBA non slotted $200 each were starting to craze, then standard drilled disks $160 each, which cracked.
DBA slotted $245ish each, were still good.
Now...
