What's everyone doing for blank face rotors when needed? I'm not thrilled about a pretty lean list of 'affordable' replacements since even the OEM pads showed noticable rotor wear on just one set. So I'm trying to find something that works for frequent replacement (ie cheap) and won't fail at the track under intermediate HPDE speeds.

I saw something called "Winhere" brand at partsgeeks that explicitly list the Evo X GSR/MR support, but I couldn't find any comments anywhere, so I thought maybe this crowd had some experience.

(The price looked crazy low compared to MSRP as well as other published prices from performance outlets.)

 

Look into girodisc

 

this

 

Uh... those girodisc two piece rotors are like $750... he said affordable.

 

i say go with the centric premiums

 

For a little background, track rotors are great, but out of my 31,000 on the odometer, about 600 miles are from four track days. I'm not wanting to know the great steel and $ from quality race rotors are falling away just on the DD. I'd not enjoy any benefits from that increased cost except for the track time. I did 4 full HPDE days last year, getting some speed, but until I get the frequency of time, say 8-10 days a year, I should be fine with heavy wear at the track on cheapies.

I was curious if anyone had tried these low cost things? For $190 for all four, I'm about to pull the trigger, just to see.

As long as the manufacturing process is modern, allowing good alloy mixture in molten state (lots of heat and time to powderize some of those), the worst case is cheap materials (too much ferrous iron, not enough carbon, Ti, other hardeners) they'll wear fast(er). Being a ME with a materials emphasis, I know I'm getting into risky areas because if not mixed slowly and well, the "combining" (think food network chefs) will leave particle too large in size to provide even material strength properties throughout.

Really, $190 for all around. Seems too good to be true. I sort of used to rotors being a significantly lower cost mro item in cost of ownership compared to tires; I'd hate to think this has to have the same budget carved for rotors as the tires, which are not cheap if you run the miles I do.

 

I was planning on going with a pair of slotted rotorpros (they come in to just under 300 bucks for all 4), from what Ive heard theyre awesome. I dont road course my car its just my daily driver/street machine. Supposedly the rotorpros are blanks supplied by centric too. Some people say theyre terrible, but they were all people who track their car aggressively from what I saw.

Just suggesting another option if other people say the ones you mentioned were complete garbage.

 

I think I see maybe why the track-heads are down on those you mentioned, at least what I saw; are they all cross drilled? Slotted isnt' bad on the track, but to drill a blank that wasn't designed with higher strength material weakens it, leaving that 'uneven' strength of material problem unevenly. So it weakens it at the points its been drilled. Grooves are not that bad, but the drilling is what I have read (and know as an engr) that's not safe to hit the streets with. But this is a definite lead. Thanks.

 

1+ lol

 

Centric Premiums are in stock.

They adhere to the industry standard G30/G3000 spec for rotor gray iron. (120 series)

Not quite that cheap though.

 

Dang, in March, 31k, here in Sept, 42K miles. So far, the Winhere held up to the nasty temps of bedding in with DTC60's. Absolutely no run in, impressed with them so far... I'll keep my infrared temp gun handy for Saturday post session. I'll let yall know the temps the Winheres are or are not able to handle with these pads and my OEM advan's back on for their last hurrah.

 

Centric lists them in standard series as well at right around that price.

We keep the premiums on hand back when they didn't have standards. We'll see if that has changed.

 

I've only ever seen Centric premiums. Where can one find a standard series centric rotor? The Winhere seem ok so far; machining is good quality, no runout at all and they were obviously turned in both directions.

And DANG, those OEM rotors were no lighter than the Winhere. I have all four in a box to reinstall after I beat on the Winhere's at the track. The box is about 100lbs!

 

I just have a p/n and price. I emailed to see if it's actually an active number.

It's over 13" so that makes it difficult/impossible to make on some of the commonly used automated casting equipment. Being what chinese sourcing is though - if Winhere gets it I'd guess Centric may be able to as well.

 

^RockAuto has these winhere's also; both places online show the retail price before their discount (MSRP) in line with competition grade. RockAuto does show a budget-budget product, and lists the winhere in a way as to include it in the 'budget performance' sort of category. Hopefully it's not too budget; "performance" can be ok, I'm not running r-comps yet so there's only so much grip I'm gonna be able to get so heat and torque aren't too extreme (yet)!
