The Stovebolt Site Forums The Shop Area Engine Shop So what do you do when your wheels don't fit?

The CPP front disc brake caliper kit states "May not work with some 14" wheels" I have 15's no problem right? Wrong.

I'm assuming my only fix for this will be to find a set of 16" wheels?

You might be able to change offset to get it to work. I'm running 15 inch wheels on my disk brake equiped AD truck.

There is more than one kit, are you using the 5-lug or the 6-lug. I suspect it makes a difference.

6 lug wheels with the 3 clip style hubcaps.

I've got some 15's on my 78 3/4 4x4. Just have to get the right wheel,

Maybe spacers would help, by moving the wheel a bit away from the brakes?

What ever wheel you choose, make sure it came off a disk brake car or truck. Drum brake wheels are different then disk brake wheels. I have seen some guys grind a little off the caliper so the wheel will clear, How much space are you lacking?

Wheels intended for use with drum brakes often have the wrong internal shape to work with a disc brake setup as you have just found. I have the 6 lug CPP disc brake setup on my '50 truck, works fine with the 15" K5/Blazer wheels that the truck has on it now.

I need about 3/4 of an inch to make these 15" wheels fit. I guess I can try the spacer idea... I wonder if a 16" wheel would work...

Anyone else run into this with the CPP kit?

Spacers work well, my brother has used them on various cars to make up for a lack of backspacing on his rims. If you do use spacers, make sure you get good ones, preferably hub-centric if you can find them so all the weight isn't resting on your lug studs. 16's, 15's, and maybe even some 14's should fit, again the brakes hitting is a backspacing issue. Before you buy different rims, take a few measurements and find out what the backspacing is on the rims you are looking at so you don't run into the same problem.

i have never heard of anyone using 3/4" spacres. dont think that would be safe at all.

although my wheels are centerline 15", they work fine with my power front discs.

Good quality spacers are safe, unless you have a performance vehicle with a ton of torque, or something that handles well that you push hard. I believe 1 inch is the smallest you can get. The good ones slip over your lug studs has recessed pockets like your rims for lug nuts, and are machined to fit on the hub so all the weight isn't on the studs. Then they have full length studs mounted through to bolt the rims to. They can be very useful and are reasonably affordable, but they have their place and are not for use on certain vehicles.

wow, sure enough, they go to 1". i never knew that.
here are some spacers from speedway.

Don't use spacers if you need more then a 1/4", use a hub-centric wheel adaptor it's much safer....Joe

I had this problem trying to put 15" wheels on a '78 K25. I wouldn't try to make up all your extra space with a spacer, it puts a lot of strain on your lugs. What I did was put a smaller spacer on (3/8"), then ground down the tops of the calipers some until they would clear.

FWIW, 16" stock '53 wheels don't clear the CPP (S-10, i think)calipers - even with the supplied 3/16" spacers, it's too close and rubs the rim. Everything clears except the area where the four slots are formed and rivetted to the rim.

I am in the same boat and I will need to buy rims next year, which is what I was hoping to avoid with the six-lug brake kit - oh well...

grrr. Far as I can tell, these are original wheels... They are the 3 clip hubcap style.

The killer is that I have 8 of these wheels, all 15". It would really frost my donuts to have to buy 4 new wheels with the proper hub offset.

Secondly, I haven't been able to find any new 6 lug original looking wheels that will work... anyone know of any?

Interesting. Looks like most of those guys have the same opinion aobut spacers and adapters that I do. Especially what the one fella said "get the right wheels, you'll be happier". Good advise.
