A fellow car guy told me about these a while back. After some research, I decided to give them a try and see if I could mount a set of 4x108 Mustang wheels on a 4x110 1st gen RX-7. I had to make some centering rings to adapt the wheel center to the hub on the Mazda, no one makes them the right size. But low and behold they bolted up and run fine. The bolts came from Lakeshore Wheel and Tire. http://www.lakeshorewheelandtire.com/

The bolts can make up a 2.4 mm difference in diameter. BTW they aren't cheap. A set of 20 will set you back about $60.00. But they do work. They will also open up a whole realm of wheels for us poor fools that have 1st gen RX-7s.

Edit : I'll add photos as soon as I down size them some.

Have you done any run-out testing, other than saying they run fine?

I dunno, i'm pretty skeptic.

i lost a wheel on a 1st gen before, so things like this make me nervous.

Those hub rings better be dead on... these make me really nervous.

Those bolts are designed for steel wheels that must be trued up to a center hub before cinching down.

I can almost guarantee you that you're going to have bolt breakage within a few hundred miles, and it should be spectacular...

There's a YouBoob video out there of a 3rd Gen owner that thought these would be cool to use on his car to fit wheels for Autocross racing. Once he gets to the first turn, all 4 wheels fly off the car. I would have been pissing my pants laughing.

Don't be 'that' guy. Good luck with those bolts of yours...

Here you go, dude: http://www.youtube.com/watch?v=kyMDNzhfwn0

Watch and learn.

There are things you can fudge, and things you really shouldn't.

Brakes, and anything that holds the wheels on the car, fall into the second category.

It's funny at the autocross track... until you realize that this guy probably drove to the track thru freeway traffic with the exact same rig. Not quite so funny then.

True that....... leave the 108s to the mustang guys.

The topic has been discussed several times in this section alone. You may not have have found it searching because they were called "loose head bolts" Here is the thread:

loose head bolts?



Oh no not again ----v

This has been nominated for the most-reposted video on RX-7club.com. Guess there will always be people who haven't seen it though.

Sorry, but no shortcuts when it comes to critical stuff like wheels and brakes. Cheap solutions usually end up costing a lot more in the long run that doing it right the first time does.

But pioneers have often been criticized in the past, so feel free to keep us updated on how this works out for you...

And here I thought FDs used lug nuts rather than bolts..... That FD used 1/2-13 nuts on 12mm studs. Your point's well-taken but there's no sense in finding false data.

Not going to say they won't work, since that's exactly what they're designed for. But personally, I'd feel safer with a set of these:

Or if you'd prefer 4x108 or 4x100, you can custom order a set:

I'm not willing to sacrifice safety for a set of ugly rims like that.

I'd rather sell them and buy some 4x110mm rims, wheel studs, and lug nuts.

Toyman01

We'll have to see. Hub rings are dead on. I couldn't find any the correct size commercially so I fired up the lathe and made them myself. Torque will be checked regularly for the first several months. Autocross duty will happen mid next month. I will keep you guys posted as far as problems and issues but I really don't expect any. The bolts don't have any side load on them only tension. There was no binding when tightening, and they torqued normally.

The main reason I was interested in trying these is the limited availability of 4X110 wheel and the abundance of 4X108 wheels. Not to mention the cost difference. The mustang wheels are what I had, left over from last years dead LeMons race car. They make good test wheels.

Kentetsu

Well, I guess you do have a point. Since the rims are hub-centric, the only stress the bolts will receive will be linear. The weight of the car is not actually riding on the bolts, but on the hub. Who knows? I'll be interested to hear how they hold up under the stresses of autocross...

4x110 wheels are abundant too. You have to look. Just from the picture that dust cap looks off centered from the wheel so it makes it look like they're mounted crooked. It would be safer to just bore out the bolt holes on the wheels (not really that safe at all actually...) or even better take the hubs to a machine shop and have them re drill the bolt pattern to 4x100 or something. You can do an FC hub and brake upgrade pretty easily for about $200.

PercentSevenC

Really? How?

And I would certainly not call 4x110 wheels "abundant". Unless you're talking about Australia or something. The only new ones you can get are Panasport knockoffs, which I don't care for, and the very occasional used set. 4x108 aren't particularly common either, but they're far more available than 4x110.

does that conical washer slide off that bolt?

When you get to the autocross track, be sure that somebody has their video camera rolling.

Thanks, and let us know how it works out,

Kentetsu

For wheels, check out Revolution. They are a British company, so I would look for used. I have the 13x8 and love them!

NCross

iTrader: (18)

People are pretty much giving FC chasis away so you can find a parts car for $200-300. Or you can buy the hubs and brakes for $100 each used.

rotaryPOWAH

You know, you've posted about revolution wheels before. I can NEVER seem to find any. I've tried to contact them through their website, but i haven't gotten a response yet.

How'd you get yours? how much did they set you back? (i can't imagine that they'd go for any less then a grip of ben franklins)

PercentSevenC

No, I mean how do you convert to FC hubs and brakes without the ReSpeed kit?

Interesting. If these do work I would have killed for a set a few years ago so I could run my 5x112 Work Ewings that no one would redrill. I hated getting rid of them.
