Does Anyone now if there are front hubs that will fit the 84-87 Fiero spnidles that will give you a 4.5" bolt pattern? Irealize that you will have to do a brake upgrade, but thats OK.

Steve

Short answer: No.

Longer answer: not for certain, but I've heard of replacing the rear axle carriers & hubs with items from the front of a Chevy Cavalier/Pontiac 6000 to get that bolt pattern. I'd investigate in that area. It might take a trip to the junkyard for some first-hand research.

The rear bolt circle can be changed to the 5x115 pattern using front hub carriers bearings brakes and outer CV's from a GM A-body (Chevy Celebrity, Pontiac 6000, Olds Ciera, Buick Century), with HD brakes.

The fronts... Are you good with AutoCAD?

GM's 5x115 pattern is NOT the same as the 5x4.5 used throughout the rest of the world. Don't ask me why not, or why GM didn't use the 5x4.75 across the board.

Thanks Jim, Will

I knew I could do something with the rears. It was the fronts I was thinking about.

What if you changed the front spindles, are there any that would take a minimum of modification to fit the front suspension and then let you run hubs with a 4.5" bolt pattern?

Why 5x4.5? I know it's common, but it's not easy to get that pattern on the rears. It's easier to convert the rears to 5x115 or 5x4.75.

That's because 4.5" is 114.3mm, not 115.

Hey Steve.

I've got an ad in Sport Compact Car magazine that lists a place that will custom machine adapters if they don't already have them in stock. A place called Ricky Racer in CA. 1-949-488-0165. No web page that I could find but they carry lots of tuner stuff for imports.

I'll keep it handy if we can manage to get together this weekend.

a guy at my shop knows of a shop that will take your rotors and turn them into any bolt pattern you want . i was going to try this so i could put a set of harley edition 20 in rims on my car. untill i found out you will never be able to get them to fit in the front , due to clearance issues.

Got a link or a phone number? I was going to start looking for someone to do mine.

Umm... Duh. What I meant was that I didn't know why GM picked 5x115 instead of 5x4.5 or 5x4.75.

As for the rear, if you can find BubbaJoe's website, there is a section in there that details using the knuckles from a HD GM A-body and hub assemblies from a S-10 4WD.

You might try giving Held Motorsports a call for the front hubs.

Hope this helps

Here ya go

and... here's a comment on the setup from Will from another thread on the subject

quote Originally posted by Will: Bubba Joe half-asses it again... I went into CarQuest today and looked at hub bearings. I looked at the '83-'90 S10 bearing w/o ABS, and the '90-'96(7?) w/ ABS. There's a shoulder on the back of the mounting flange on both bearings that's slightly too large to fit into the A-body upright. If you look on this page: http://members.fortunecity.com/bubbajoexx/id205.htm and scroll down almost to the bottom, you'll see two pictures side by side labeled "upright and bearing". If you look carefully at the right picture, you'll see that there's about 1/4" gap between the mounting flange of the bearing and the upright. He just took a part that doesn't fit and used it anyway. Also, the holes in the mounting flanges of the S10 bearings are threaded. They need to be drilled out before the bearing can be used with the A-body hub carrier. I would never do this swap the way Bubba Joe did... HOWEVER, with a little lathe work on back of the bearing to turn that shoulder down it could work...

hey Will the reason for the 5 X 4.5 is I have a set of 18" X 8" Enkei EX Ageis wheels that got for a song

If your wheels will fit best without adapters or spacers the guy that wiccantoy suggested would work for you. You could have the front rotors, and the rear hubs and rotors, redrilled to the same bolt pattern as your wheels - possibly for the same price or less than adapters. Modern billet adapters are strong and reliable but they do add unsprung weight - better solution is if you can do it without 'em.

Thanks perk, redrilling to the new bolt patter sounds the best at this point. I've looked at the rear hubs and it might be tricky to find a location to drill the 4.5' bolt pattern. i have access to a local machine shop who would be willing to do the work though.
