Ok,

I've searched and I can't seem to find the info I need and figured I could appeal to the good folks on here.

Are the hub centers for the older FB's with the 4x110 bolt pattern the same as the later SE's with the 4x4.5 bolt patterns.

Reason I ask is because I have the later 85 SE front suspension going on my car with the 4.5 pattern but the rear axle is still a 4x110.

CCW can drill two bolt patterns in the same rim and I'd like to be able to swap them axle to axle without adapters.

Any thoughts?

Thanks

 

I don't know about the hub diameters but the offsets are different, so the rear wheels would need spacers.

 

110mm = 4.33 inches, so no.

4.5 inches = 114.3 mm

 

He's talking about the diameter of the hub center that fits onto the wheel to keep the wheel centered.

Frankenmazda: If they are different, you could always have a ring made to correct for any difference.

 

The SE rear axles are longer than the non-SE axles. You would need spacers on the rear to use the same offset wheels as the front. The difference in offset is around 20mm.
With a spacer that thick, I would advise using long screw in studs on the rear axles, to insure a secure mounting of the wheels. Either that, or have the axles drilled to accept press in studs, and use studs long enough to allow the lugs to have at least 3/4" of threads to hold the wheel on. If you are going to the extreme of redrilling the axles, it may be best to just have them drilled for the 4.5 pattern.

 

One reason our wheels are hub centric is to aide in mounting since we have lug bolts instead of studs. Many aftermarket wheels aren't hub centric, yet seem to work fine. Rings will work, you may need to find the specs or measure both hubs, then have rings made. Personally, I'd locate a pair of front SE struts and not deal with the dual patterns or offsets.

 

I do have SE struts for the front hence the differing bolt pattern. CCW street wheels have hubcentric centercaps. I can measure the fronts since I have both the SE and FB struts. The rear though I can't because I have the 81 GSL rear axle. I was trying to keep everything hubcentric and but I guess it really doesn't matter. I am going to screw in studs/lugnuts because I hate the lug bolts anyway. If I have a problem I just won't use the CCW centercaps.

thanks for the answers

 

Keeping hubcentric will help to keep your balance correct. Relying on the lugs to center the wheel can give you problems. Since your going to need spacers as I noted anyway, you can get hubcentric spacers and make sure you don't get annoying vibrations.

 

My bad; short attention span.

 

You may have another option. Have the axle flanges drilled for the SE bolt pattern and install pull through/knurled studs. Then all you may need is shims for the difference in offset.

 

He 'might' still see balance problems. The hub ring makes sure the wheel is centered in the hub, it's harder to be sure of that by relying on the studs and chamfers in the wheel holes.
