of these rotors here,there has been a lot of threads here recently about rotors and these look like nice rotors and a good price free shipping to boot.

You have to make sure they're sending you front and rear rotors. the rear rotors have a slightly different offset and the additional holes for the parking brake adjuster.
Email the seller first, describe the difference between F and R and get their confirmation that they're going to send you two fronts and two rears.... if they still send you four front rotors call the credit card company, fax them a copy of the email to the seller and have them get the money back for you....

I ordered a set too, from "rotorstop inc" on Fleebay..... can't wait to see what I'm getting (I have their email stating I'll get F and R rotors and two different part numbers for F and R) ;)

Here's a pretty good install video that also shows the problems you can run into:

I measured the offset on the rotors that were on my car. Front and rear were the same. I measured another set on a car, offset was the same front and rear. And yes, the rears had the park brake adjustment hole and the fronts did not.

Maybe the slightly different offset is an urban legend.

NO it is NOT, the rears have a thinner flange/Face where the studs stick through...you can measure the hat from outside and it's all identical....but the thickness of that mounting face the hub/wheel sandwich with is different, the fronts are thicker by almost a 1/8 inch....maybe a 1/16, but it's enough to mess up the brake pads.....

I chaulk it off to one end not talking to the other when designing the car...at the engineering lab...so they too the easy way out when the problem turned up, and they had too many calipers mount brackets, so just ordered more rotors for whatever end, and 'fixed' the problem with another part #....

:bounce::bump:
 
I stand corrected!

The offset is 1.85 on both BUT the flange on the front is .38 thick and the flange on the rear is .28 thick as you describe.
 
Is anything wrong with shimming the caliper or the rotor get the rotor centered between the caliper halves ??

Yea But,

if the measurement from the inside of the flange (mounting surface) is the same who cares. That just means the wheel is 0.1 further out.
 
The inside measurement is .100" different (from inboard side of rotor down to the mating surface for the spindle or hub).


Did you order your rotors ??

Apparently, GM. Since they love standardization, I would imagine there IS a reason.
 
when i get ready to order them i will call them and ask the these questions to make sure they have ft rotors and rear rotors that are correct. Do they look like they should be good rotors and is the price reasonable?
