17's on my Denali?

[petethepug]

Interesting, I stand corrected. 17’s will fit on our NNBS. My first thought was using the 17” aluminum rims off the NBS Denali. They’re tuff as nuts, aluminum and don’t deteriorate in rust belt.

The above thread has info on it. I had heard some NNBS had smaller rotors and/or calipers. They’re all 330 fr -345mm rear rotors.

The only exception is 07/08 LY2 4.8 V8 w/ rear drums. The 09 4.8L got 20mm (vs 30mm) wide discs in back that year. If you mix the 20mm w/ the 30mm you got problems

What are the pertinent differences between the front brakes on, say, a 2010 Suburban, vs a 2010 Yukon XL Denali?

There's 4 18" x 8.5" Chevy wheels:
20937769 / PZX
20937771 / RD1
23205585 / RCV
23480949 / REG

And three 18" by 8.5" GMC wheels:
20937768 / RCW
20937770 / UHN
20942022 / RT5

Previous owner of my Z71 equipped it with UHN wheels.

Forgot to mention a few things:
No Caddy Escalade 18" by 8.5" wheels. Only one Escalade 18" by 8.0" wheel, available in two finishes.
It won't handle as well as the Chevy / GMC 18" by 8.5" wheels.

The N93 / N94 17" by 7.5" Caddy wheel is a pretty durable option that'll always look great,
but there are 17" by 8.0" Chevy / GMC wheels that'll handle better, if handling is a priority.

How do I make use of Denali / Escalade brakes?

Are the Denali / Escalade front brakes functionally superior to the other GMT900 front brakes?
(Not really concerned about the rears.)

GM slapped the same front / rear brakes on all the full size 900 SUV’s. The exception being the 4.6L rear brakes.

Not sure why GM thought the same caliper / discs from a 4.6L 2WD Tahoe would be alright for a AWD 6.2L YXL Denali.
