[s-cars] Slotted vs. Drilled (was - Link to slotted rear Zimmerman Rotors)

[Frank Amoroso]

Nothing standard about coleman rotor patters vis-a-vis the 993tt rotor
bolt pattern.

BTW, my cross-drilled, directionally vented, 330x32 (31.75 really) or in
'Mericun: 13.0 x 1.25" Coleman rotors performed flawlessly while I had
them. Including some heavy track days, as well as some good ol' fashined
F'ing around, putting passengers into their seatbelts, HARD, without any
warning. I've made more than a few grown men get really nervous about
quickly reducing stopping distances at very high speeds.
