Re: urq brake UPGRADE! was Re: '82 urq: Uneven Brake Pad Wear (right to left)
Thanks for your input, Mike! I'm running these 3 combinations: 205/50/15
on 15x8 Ronals, 205/55/16 on 16x7 Speedlines (A8 wheels), and 225/45/16 on
16x8 BBS's. The tests were run with the 205/50/15's installed. The crappy
Yoko 403's were on the back so that the car would oversteer a bit on the
track (on purpose), but I felt similar lock with the good SP8000s on
BTW, another data point: I'm running Porterfield R4 carbon kevlar pads up
front and Ferrodo carbon metallic pads on the rear. The rear has slotted,
non-vented rotors; the front OE ventilated rotors (new). Braided steel
lines all around with Girling DOT 5.1 (non-silicon) brake fluid (new).

Do NOT use this master cylinder if you're buying one new. Use the '90 200q
one intead! Same specs; though 4 brakeline connections vs. 2!
