'17 Impreza Sport, '15 OB 3.6R
Hey all, just wondering, for those of you who have Porterfield's R4-S (Street compound) pads, what kind of life expectancy can be expected.
I'm a pretty normal driver I guess, I mean I'm more aggressive than your average Camry driver, but that's about it. When I get the chance I do two autocrosses per year (averaging two runs per), but I didn't get to go to any this year at all. So, no I'm not a racer.
Another possible factor... I am using OEM rotors, but today ordered some new front rotors, as I had a steering wheel shudder at high speed when braking. Warpage. Brought the car into a very nearby brake/muffler shop that charges $15/ea. to resurface rotors. I was hoping they could, but the guy called and said there's "about 1/4 inch of warpage, if we turn them they'd just warp in a couple weeks."
So, had to order new ones. I could've gotten new OEMs really cheap from Exeter Subaru (www.subaruwrxparts.com), since they sell front WRX pairs for $100 (no sales tax either), but I opted for some Brembo solid cryogenically-treated versions from www.FrozenRotors.com . OEM size, no cross-drilling or slotting.
$84/each, pricey but I've heard tremendous things about cryo treatment.
Anyway!! With the new rotors, maybe that'd be a factor, maybe not. I have the pads on all four corners. Rears are still OEM, they're in good shape according to the shop.
