Have you tried rockauto for the calapers? Looks like their $75 for loaded calapers and the rotors are about 35. That should help shave alittle cash.

I upgraded my rear brakes and the best deal was a result of buying loaded calipers from rockauto and rotors from Advance Auto Parts. Twas pretty cheap...

I went with the dimpled and slotted from brakeperformance.....

If it was me, i wouldnt mess with drilled rotors.. gettem just hot enough and they'll crack and warp pretty easy.. At the MAX i would do slotted, but if i was buying them to go on my truck i would just stick with the plain rotors.. But thats just my opinion.. I would deff check rock auto though, they have great prices.

Did the 05+ calipers ($40 at local auto yard, IIRC), powerslot rotors all around, hydroboost conversion (cost $80 at the auto yard, thanks Atomic for the step by step guide), and Goodrich stainless lines all at once. Night and day difference, didn't know a 5000+lb SUV could stop this well.

Personally, I would do hydroboost first, then go from there. Hydroboost makes a significant difference in stopping power and required effort. You might be happy after that alone, and save yourself a few hundred dollars over going with bigger rotors.

The most bang for your buck upgrade I did was Slotted rotors from fleabay. Did nothing else and cut 60-0 by 30%. 250.00 or less and plated so they look nice for a long time. All 4.

I was looking at the calipers for the suburban with 9900 gvw. I'll get part numbers when I get home.

Ok I so the quote doesn't have it labeled fr and rr, but the calipers for the front are from an 05 Silverado and the rear are from a 3/4 Suburban 4x4 same year. They are new Wagner wih thermo-quite pads w/ bracket. Ok here are e part numbers with prices:
Calipers
TQ25433- $73.70
TQ25432- $73.70
TQ25365- $79.80
TQ25364- $79.80
Rotors- house brand
2x 580279RGS- $94.22 for both
2x 580165RGS- $76.56 for both
For a total of $477.78, I think he did it under a shop prices but not sure.
All part numbers are from Orielly auto parts.
Hopes this helps out.

Rear rotors are 6lug

Not on a 3/4 ton.

So '05 front calipers and rotors are 13", and 99-02 are 12"?

What about using eBay rotors? They are decent looking and pretty cheap.
