How much can I grind??

I know its been asked many times but I just want to make sure..I just bought used chrome 8 hole 15x8 American Racing(It looks like the wagon wheels but chrome) wheels to go on my 10 bolt..I installed it and it I cant even turn it.Its got 4" backspacing..Is this too much backspacing?Or can I safely grind the caliper/backing plates??Ive never done this before..BTW whats the best tool to use..I have a low duty air grinder is this enough or is it much easier(or woth it) to get one of those heavy duty angle grinders??

I read in the archives to use paint to figure out where to grind but Im just afraid I might take off to much and break

OT..The 6" lift is in but I still need two rear shocks..The casualty list includes 2 flex brake hoses,4 feet of brake lines,1 rear spring pack,1 brake cylinder,1 gas line..Anybody know how to figure out the legth of shock I need?

<font color=green>Need more info - what year is the truck and what kind? 1/2 ton, 3/4 ton? The only vehicle listed in your profile is a IROC Z, and I doubt that these are going on there... You should not have to grind to fit a 15" wheel on a 6 lug, but may need to on a 8 lug. A little is OK, but I wouldn't take much off of a 1/2 or 3/4 ton caliper.

Re: How much can I grind??

You can eyeball it (which is what we've done in the past) or if it starts looking like things are getting thin you can use latex paint or water soluble lithium grease. Either one is pretty easy to get off. I've only done this on IFS trucks though.

We use a mini die grinder with a carbide bit. You can also use a disc grinder you get from harbor freight for $20.
