well there ya have it
just a quick bolt together with what I had kicking around to show exactly what Im on about...
this picture is a little misleading.
#1 the rotor is resting on the very back of the caliper hanger which has a bit of a step in it. really there is only about a 1/4" difference between the hanger and rotor widths.
#2 the rotor is sitting at a bit of a slant (theres that 3/8" more backspacing I was talking about)
and lastly
there are a lot of gaps everywhere because nothing is really clamped down yet
However this quick little mock up told me a lot about this theory, namely the distance between the center of the hub and hanger was right where I expected it to be and it all seems very plosable.
So taking advantage of autozones 20% off online orders over $100 I ordered up a c6 zo6 355mm rotor.

sweet, the C6 rotor is not as deep. So between that, and you may be able to move the bracket to the other side and get it to line up nice. Oh, and the holes look bad *ss. 😀
as stated before, if the thickenss of the mounting surfaces of the rotors are the same from c6 to jimmy than based on the dimensions I have found on line Im expecting the see 3/8" more room between the spindle and rotor. Picture is funkey because there are gaps anywhere and nothing is too tight but I think I am good shape as this is all based on the dust shield being in place. so if i need to move the pab out I can take out the dustshield, if I need to move it out more I can shim between the PAB and the bracket I made. If I have to move the PAB in all I have to do is shim between the hub and spindle.liquidh8 said:
the 355mm rotor cant get here soon enough!

bad news bubba...liquidh8 said:
started looking at the rear disc conversion. Because the ls1 PABs bolt to the outside of the backer (opposite of the front brakes, the pab has a thru hole an the backer plate has a threaded hole) it wont work unless we make custom backer plates.
basically what is happening is the zo6 rotor is thinner than the ls1 rotor so the PAB needs to be relocated 1/2" away from center of car and out 0.695" from the center of axle.
Because the PAB bolts to the backer plate with the PAB to the center of the car side of the backer plate moving it away from the center of the car would require it being moved at least 1" out from the center of the axle.
this would require a 14" (355.6mm) rotor
So far the CTSv is the only sutible replacement asside of the 6 lug vs 5. I will look to the trucks after lunch
Either way it looks like it will have to be a trick fully custom backer to keep the ebrake
*edit*
My life moves just this fast!
2010 camero SS has a 365mm rear rotor with the proper 5 lug pattern. The only issue is the center bore will need to be opend up 3mm on the diameter to mount. Same "clamping area" thickness of the LS1 approximatly 3/4" thinner in profile than the ls1 rotor so plenty of room for an adaptor plate.
However, you will really need to step up your rims and your rear rotors will way bigger than your fronts! LMAO

I did some digging last night at the end of the day in work here, and came to a similar conclusion. To do anything with the LS1 rear, to keep the ebrake, would require a custom backing plate. :?
well if you have no desire to run the 2010+ camero rear disc than as I stated before, Im fine with less breaking in the rear as I feel they will be prone to locking any how.liquidh8 said:
I did the grun work and worked out a prototype bracket for the swap, some one hit me up if they want a set to test out the theory.

I would run one, I need to keep the ebrake though. I think the we could make a custom rear bracket, that goes between the housing flange and the backing plate. It would also act as a spacer to space out the ebrake shoe. Then, just cut the ears off of the ls1 back plate.
Thoughts?
