Ok i was installing my LS1 rear brake setup this weekend and i ran into a problem
i think i know what the problem is but im hoping someone can confirm it for me
when i go to bolt the caliper bracket/caliper on it doesn' fit, it hits on the roter.. and after looking at it i think the place i bought disks from sent me C5 rear disks instead of fbody ones

these ones seem to have 3/4 - 1 inch back spacing and i think the fbody ones should be more than that.. can someone confirm if they have ls1 rears if there should be more backspacing than this? if so i need to get ahold of the company asap to get this straightened out

An here is a quick pick of the rear, of course i cant bolt the caliper up since it hits the rotor :rant:
but i had to see how it would sit
i have belltech leafs and 1inch blocks, i was actualy expecting it to sit lower but i guess it still might settle a bit still, and the rims are hyper black 18" c6 z06's tho thats a bad pic and they almost look chrome in the picture

And i still need to finish doing my C5 front conversion, before its back on the road
my truck hasn't spent more than a few mins on jack stands until now..
im afraid its starting to like sitting on jack stands and that scares me :lol:

Re: Rear disk help!!!!

Your in luck. I just happen to have a set of 99ish f body rotors in my basement.

Took some quick pics,

Looks like around 1 7/16 by the way you measured and around 2 1/4 on the backside.

The truck is looking good, when are you going to bring it back out this way?

Re: Rear disk help!!!!

thanks for the pics Tony,
the ones they sent me are about 3/4 of an inch so they are defiantly the wrong ones..
as soon as i put them on the truck i knew they had to be C5 ones but then i started questioning myself thinking i did something else wrong.. so i wanted to double check with someone with some Ls1 brakes :lol:

No idea when ill be back out that way, would like to come up for the canadian syty nationals but we will see how my schedule works out this year :oops:
