drag lites, and back calipers I have a set of 8inch wide by 15 inch tall drag lites with a 10inch DR for my 2000 camaro, and i am having trouble with getting them to clear the caliper. i have grinded the **** out of them like people say to do, and around the edge they still wont fit and i dont wanna grind so much that i have to worry about them breaking. i got the fronts to fit. but on the back i was wondering if a 04-05 caliper off a gto would work or so a 95-97 Z28/ss caliper? or do you think i would have to buy a bracket and rotor to? im throwin this out there to try to get some ideas of what to do. Thanks

well what i am wanting to know is if you guys know if a 95-97 lt1 fbodys caliper would fit over the ls1 cars rotor? and if so would i have to get a new bracket? or would i have to get a 95-97 caliper, rotor, and bracket? and if that wont work do you know if the gto caliper would work. i dont really wanna use a spacer if i dont have to because i want to suck the wheel in i dont want it to stick out. and my wheel is a 5.5 back spacing.

yeah i didnt know what all i would have to change. little more work than i was hoping and yes the ls1 brakes are bigger than the lt1. thats why i was seeing if i could switch to a lt1 brake pretty easy.

I am not going to use a spacer on the rear wheels, which have all the torque being applied to them. I'm using a 5/16" spacer on the front with no grinding.
I have a rear end sitting on my garage floor, it should be easy to pull the axles and swap the backing plates while it's out. I wanted to put a T/A cover on it anyway.

I just bought drag lights today 15x3.5-15x10 for $500 will i have an issue with fitment on a 2000 z28 as well??? My back spacing on the front is 3.5 an the back is 7.5 i was told the back will be fine and the wheels will work great, but the only thing is i don't want to run wheel spacers an be breaking studs off on the street, the car never see's the track it's a DD 408 bottled sleeper so it really has traction issues an 75 MPH an it's a M6 so a bias ply on the weekend is the warrior of choice! What did you guys use on the front for weld wheels, an what did you guys do on the back?

on the front of my camaro i have a 15x3.5 drag lite and a bit of grinding i got it to fit, and if you get your 15x7.5 back space to work on the back PM me and let me know because i will take mine back and get a 7.5BS, i dont want to use a spacer either but theres alot of grinding for a 5.5 backspace.

You have the right 7.5" backspace for a 15x10, but the rear calipers will get in the way big time on an LS1 car. Some guys here have ground them down to the point that it's scary to get the Welds to fit, other guys have ground them to the point where they got scared and quit or even ground right into the caliper pins and ruined them. It won't be easy. I haven't gotten my rears on yet, still weighing my options.

I was told that the front's have alot of grinding to be done, but they will fit without a spacer an the track officials won't kick me out for improper safety. The backs with 15x10 with a 7.5 clear fine from what PBJ in st. louis said maybe a lil rub but grind off the ribs on the caliper. You have to have a narrowed rear to run that back spacing i read a thread on it recently look up narrowed rear in the wheel section with welds an the other one was with a billet specialties. You need different back spacing. With a 6.5 you'll grind a little bit, but with a 7.5 there isn't any grind maybe scratching the surface if any. My buddy just told me that with a 8 inch wheel, 7.5 backspacing an to go with a 27/11.5/15 hoosier you should be ok. They told me the wider the wheel the more the back spacing an the wheels lip will get more shallow.

Check the backspacing on the fronts, it should be 1.75. For the fronts you can either do some grinding on the calipers (shouldn't be too drastic, there are pics on this site somewhere) or you can just use a 5/16" spacer like me and do no grinding. Definitely get longer ARP studs on all 4 corners though, either 2.5" (like mine) or 3.25", which is probably safer but twice as expensive, more of a PITA to mount and remove the wheels each time, and kinda goofy-looking when you don't have the Welds on there. The 2.5" are 1" longer than stock and a lot stronger so those should be ok. The front studs were easy to swap but the rears will be tougher, especially if you don't have traction control.
You have the right 7.5" backspace for a 15x10, but the rear calipers will get in the way big time on an LS1 car.
