Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

Ok Guys "WARNING" These wheels are not for the faint of heart!!!!

I just bought these for my 66 burb. The good- They fit and look great on the rear. The Bad, (I do have disc brake conversion.) In order to make these fit on the front the snout of the rotor will need to be machined down, and not just a little! You will need to find someone who can cone the end of the hub to fit into the two step downs in the wheel , then the fun begins, you will need to trim the spindle down as far as possible and re drill the cotter pin hole. Then you will need to cut the end off the dust cap untill it is a 1/16 from the spindle and then weld a cover (i used a fender washer) to fill the giant hole in the dust cap . next you will need to break off the tabs from the BOSS cap and test fit it over the spindle with the wheel installed,and then silicone it to the wheel, you may still need very thin spacer behind the wheel. If the guy in the pics didnt go through this he must have some other front end like a Camaro or Mustang II. Good luck if you buy these wheels.

Hick-up Pick-up, thanks for the detail. You're right sounds like a lot! Your Burb looks sweet!

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

Hickup pickup,... the '68 swb that I posted had a stock C10 pickup front suspension (bagged).
If I had known of all the problems,... I would have asked him for details.
I was looking on the Boss Wheel website and checked out the "accessories section". They show all the different centercaps for all the Boss and Eagle Alloy wheels. I'm trying to determine if the centercap from a Boss 304 wheel will work. (part#3148-06) These are more "round" instead of flat like on the 338's.

So if anyone has a set of Boss 301, 303, 304, 306, 307, or 308's,... could you please pull the centercap off and measure cap, or the bore of the wheel so I can see if these will interchange. I have sent an email to Boss Wheels,... but have not heard back from them.
Thanks again for your detailed input. This is a little more complicated than the "Coy's cap spacer issue".

The wheels look great. I'd be interested in hearing from some more people who have installed these on our trucks. It does sound like some work is needed. If its do-able, i'd be interested in a group buy also.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

The cap selection may help the dust cover a little but, stock it is nearly 3/4 of an inch that needs to be eliminated and the machining of the rotor will still need to be done. The reason I indicate the cone shape is to keep the streangth in the hub, if you step machine it it will be very thin around the race and may break. Also you will still need to remove any clips and silicone the cap on, there is no room for the clips unless you run a thick spacer. I looked at other caps from BOSS and none will give you enough room.

I am not trying to scare you off these wheels (they are *****en) I am just trying to eliminate your futue frustration after a costly purchase. I paid $177.00 each for mine and was able to do the mods myself.

What about using spacers on the front? It sounds like a lot less hassle than stated above if they will work...

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

they would need to be nearly 3/4 of an inch thick. plus I have a PB crossmember which pulls the wheels in about 2 inches per side and I have had to trim my fenders beyond the lip just to get them to clear when the bags are deflated so there is not much room for a spacer let alone a 3/4 inch spacer. Sorry to be the bearer of bad news but this is kinda what this website is all about!

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

Have you got any close up pics of your rotors clearenced or the wheel on the rotor without the cap so we can see a little better about where the problem is? I have a '71 with a 4.5" static drop. I don't have a dropmember, so could I get a spacer and get a wheel with a bigger offset? Just curious.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

I got an email back from Boss Wheels tonight. They said that they are working on a new cap design,... but it won't be available for 4-6 weeks.
Maybe if everyone sends them an email,... they will correct the design flaws of this wheel.

The problem is they don't see it as a design flaw. They see it as us using their wheels on the wrong application.

BTW- For those that argued with me about these not being available in a 5x5 pattern.....I told ya so...

As far as the Coys wheels go, I believe the problem with fitting comes when you do an after market disc brake upgrade. I have a 71 with 2.5 "drop spindles and had no issues. They went on with no mods. The same could apply to Boss wheels.

Do you think there would be a problem with an 18x5 rim or just the 20's

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

I applaud your persistance in this endeavor. That being said, will the center caps attached w/silicone be able to withstand the heat generated by front disc brakes & remain attached?

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5

I will be puting a nitrogen infused intercooler to disipate the generated heat transduced through a ridgid Kenuter valve perpetuated into a Flux capacitor.thus cooling the center cap.


I think the PLASTIC cap would melt long before the silicone.
