Got the front of the car up on stands and popped off the left front wheel to begin to figure out the 4 lug to wide 5 lug conversion that is on the car now.

 

I knew there obviously were adapters to the wide five configuration,

 

I noticed what appeared to be a seam in the adapter, and that the adapter measured 3/4/' thick, which seemed awfully thick.

 

I popped off the adapter to find a spacer behind it, the combination of which created the apparent seam.

 

So what I have, as illustrated in the pictures below is the four bolt disc brake - four bolt spacer - wide five adapter - wheel.

Back to the notion of shorter studs from the brake thru the spacer and adapter and counter sunk, shallower nuts to hold the adapter and spacer to the brake which should provide an almost flat surface to accommodate drumskins.

 

The studs just came out of the brake with an allen wrench so now I need to go find shorter ones as well as matching shallow lug nuts.

If you really want a flat surface, go find (fastenal.com, etc) some Class 12.9 flat-head socket cap screws in either 12mm or 14mm (or whatever matches your stud threads into the discs). Then have a machine shop change the existing taper of the 4 lug nut recesses on the adapter to match the angle of the screw's head. Bolt it on with red loctite and you'll have all the inner bolt heads recessed with a fully flat area to mount the drumskins.

 

I'm not sure you'll find lug nuts that will ever be short enough to fit under anything.

May well come to that, buddy.

 

I wanted to day the same thing, but I didn't want to be a total downer. I think the Wide 5 disk brake kit would be the safest and quickest way to get the look you want. What's it going to cost to get everything tapered, cut, chamfered, etc? I don't think the drum skin is going to look 'right' on top of the two adapters. With the thickness of the adapters, I think the center 'cap' will be recessed back further than it should be.

 

That being said, an innovator should always exhaust all options. If everyone listened to us naysayers, we'd never have anything cool or new to marvel at.

 

Keep us posted, but don't risk safety for a few extra bucks.

 

I'll go back to the naysayers union hall now... you have to attend the meetings or they won't let you stay.

You have a point with the center's being further recessed. However, if he were to use ones like this: http://www.cbperformance.com/P...asp?ProductCode=4430 the front skin has no center opening so it wouldn't matter how far back it was recessed. Since he already has wide-five drums on the back, they will look normal too.

 

They look to be the same ones on Todd's car here: https://www.speedsterowners.com...68#11145799296150668

 

I've seen several example too that paint just the center nipple on the fronts black to match the exposed axle nut in the rear to emulate a separate hub dust cover.

Bob-

 

I've got Airkewld brakes on my bus, and I've dealt with Pete. What you want is not a specialty part-- it's just specialty hardware, and you can get that from McMaster Carr or Fastenal. If Pete had it, he'd most likely be buying it from McMaster Carr or Fastenal.

 

Art's link is actually a fantastic deal-- it's $13 or so for a pack of 100. I'd pay attention to the head size, you want a reasonably big head to get a good bite on the spacer.

 

McMaster Carr has everything you need. They have the bolts in any length you might need. I got the part numbers for the bolts, the countersink, the whole shooting match last fall. You can buy in quantities of 5 for $12.14. The P/N for the M14 (2.0) x 40 is 91294A414. The link is here (Link to 14 mm Flathead Screws) I don't think 40 mm is going to be long enough for you to use your spacers, but thats OK-- they've got longer ones as well. They ship from Chicago, and will be here in the AM if you order before 7 PM or so.

 

Fastenal has a branch in every town with more than 35 people in America, but none of them stock anything. Fastenal will be slower and cost more than McMaster Carr.

 

The whole thing would take an afternoon, and you'd be ready for drumskins (which I'd buy from CB for $100- Here is the Link to the Drumskins). The painted (non-chrome) wheels are the hard part-- fopr some reason, they only come in about once a year from China. CIP had them last fall, and still lists them on the website for $50/. (The Link to the Wheels is Here). I'd get a set before they are NLA for another 6 months.

 

50 bucks would take you all the way with McMaster Carr, tool and freight and a trip to Perdue's included. A Benjamin gets you the drumskins, 2 more get you the wheels. You can countersink your adapters on my drill press so the labor is free. That's as far as I can take you, my friend-- this is by far, the least expensive way to get to wide 5s there is out there.

Yes, they are $275 after delivery. For 4 wheels. That's as cheap as it's ever going to get, unless you live on the left coast.

Yeah, and in all fairness - that's not a bad price for a really great improvement to the looks of your car. It looks like Bob could go pick up a set and save the shipping.


How's the quality? thin? crappy paint? or good stuff?

 

If I had a car, Id be thinking long and hard about them.

Bob lives in Peoria. That's a long haul from CIP1. The quality is like everything else from China-- it's what we've got to work with, unless you want something fully custom that costs 10x as much.

 

I've got a set of Biven's Aluminum wide 5s, brushed and clear powder-coated. I've got every bit of 10x as much as the Chinese steelies in my wheels. Sometimes, if you ant to play, you've got to pay.

 

In this case, not so much. This is as close to free as any major upgrade will ever be.
