There is less brake fade.

I look at it this way: these caliper + rotor assemblies come on vehicles that have been tested time and time again so I don't see much of a performance loss.

I should have been more clear, I meant strictly speed-wise. I would hate to be losing tenths, but isn't the rotor only a pound heavier per side more than stock?

GT500 front rotor: 26.2lbs - GXP front rotor: 24lbs

2009+ CTS-V/2010+ Camaro SS rear rotor: 24.05lbs - GXP rear rotor: 15lbs

Front CTS-V calipers weigh about the same as the GXP front calipers; I've weighed these personally. No clue on the rears.

You can use your stock GXP banjo bolts, but you either need to double up the thin copper washers or get extra thick ones - take another look at the pics.

Gotcha, that'll do it then.

And for the Caliper bolts, did you mess around with CTS-V bolts, or just use M12 x 1.75 x 60mm bolts?

Use the V bolts since they're the bolts that are made for the calipers.

You just need to use those sleeves. I have some extra sleeves if you want to buy them.

Looks like GXP25 has you covered - I ordered the M12 bolts and sleeves from McMaster-Carr. The sleeves keep it all centered, so they're a must unless you want to drill and tap the calipers for M14 bolts and you can use your GXP ones.

I can't locate the cts-v bolts online. I saw a thread on a Cadillac forum where a guy actually used a m12x1.75 60mm, because he didn't want to wait. Gxp25 do you know where I can order some online?

P/N 18041878 - M12x1.75x55

You need four.

EDIT: You can get them at any dealership. I tend to get most of my GM parts from the dealership if it's reasonable enough. That way I don't have to deal with shipping costs. I only do that after checking their advertised price versus GM's true online price.

If I find myself being gouged, I tend to buy from http://www.group1autoparts.com

They tend to have some of the best prices and cheap shipping.

Yes, it works great - waiting till I need tires for the smokey white burnout! I still need to get to the track for a test & tune, but after a ride - my trans builder wants to use them in all his performance builds.
