Anybody try these out?
They look like a decent deal at $60/side.
If you want to do the more challenging Auto-X courses or road races, you've picked the wrong vehicle. As well, I doubt those rotors would be any good on a proper race vehicle.
They are most likely, cheapo replacement rotors that a fly-by-night company bought up, sent to a machine shop to have holes drilled in them and slots cut into the surface.
That is the ABSOLUTE WRONG WAY to make SLOTTED AND DRILLED ROTORS. Most Porsche racing teams, when they get a new Porsche, take the OEM slotted & drilled rotors (made the right way) off and put on solid rotors. In many race conditions, the effects of the holes and slots hurt more than they help, some race conditions they do help more, but its usually the more severe race conditions.
On the street, they are nothing but show. The only thing the drilling and cutting has done to that replacement rotor, that was NEVER Designed to be drilled or cut, is too reduce the mass (a direct relationship to the heat absorption) and hurt performance and weaken the structure, making it more likely to warp or crack.
Warping rotors come from either inferior rotors or overheating the good rotors. Riding brakes down mountain sides, or standing on the brakes after you overheat them, so the pressure deforms the softened metal, etc.
Get good quality replacement rotors, no holes or slots. NAPA sells them for like $60 a side, never tried them, but I have YET to receive an inferior quality part from NAPA, something you can NOT say about Auto-Zone, AdvanceAuto or CarQuest.
As far as pads, I get the NAPA "AE" pads, about $55. "AE" is in the part number, they call them "Premium", but its their mid-level pad, not the cheapest not the most expensive. It comes with the anti-rattle shims, etc.
There is also a new, supposedly impartial, certification,
DEA3? for brake parts, If it gets the certification it means the parts will perform as well or better than OEM on the vehicle. The pads/rotors I buy all have that certification on the box. I did some reading about it a few years ago, seemed like a good idea, but I don't really look it when selecting pads/shoes, it just seems that I see it always on the box for the pads/shoes I buy. Funny, the only set of pads I've bought that did NOT have that seal on the box, a cheapo auto-zone set I put on my Neon R/T, performed horribly, definitely longer stop distance than OEM. So, that seal just might mean something, seems every brake part I've been pleased with the performance had the seal, every part I was disappointed did NOT have the seal. Yes, antidiotal, but it appears to be something to look for when buying pads.
