Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Unless I am blind, this does not apply to the model of trucks, such as my son's 86 Silverado. The 18 X 8" wheel appeared to seat directly onto the front disc brake hub without issue, except the center cap clearance. The 20 X 10" wide rear wheel seats well up against the drum and the backspacing looks good to align with the springs and the inner fenderwells on this year of truck. We seated the front wheel with a 3/16" thin spacer, just to make sure the cap would seat right. I am going to look again, but I thought we covered every angle the first day.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
So a quick recap... Looking at these wheels in 20x8.5 and 20x10 for my '68 SWB Fleetside with a 12 bolt rear with drums/'87 front with discs with a 5 on 5" bolt pattern.
I am unsure if the set up is with a 1" or 1.25" thick rotor, but if it is 1" everything should work just fine up front? It is dropped ~5" with spindles and springs up front as seen here... But if they are the 1.25" thick rotors, then I will need to change out rotors, calipers, spindles, balljoints, etc. just to get the wheels to fit up front...? Or shave down the "dust cap" area on the rotor every time? Sorry if it has been mentioned before, it's just after reading through a billion pages about "new style" 338s, 1" this, 1.25" that... My brain just got a little fried. Thanks, -Tyler Last edited by spazzyfry123; 01-06-2011 at 04:16 PM. |

Up front, you can (1) use 1/4" spacers (which will push the wheels too far out to look "right"), (2) machine down the hubs (exact dimensions are provided with a mechanical drawing elsewhere in this thread, probably somewhere in the last 10 pages or so), or (3) swap in light-duty (1") rotors, which will also require different spindles, calipers and anything else associated with that downgrade. You sure you don't want to consider something else that's designed to fit? Would probably be less expensive when you add it all up and would definitely be a lot easier.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
I really like the style of these wheels, they look great on what rides have managed to accomodate them and Ive read through all 37 pages of posts but curious what the big difference between the Boss 338 and AR Torq Thrust II's or the AR Torq Thrust C100's?
Is cost the biggest deciding factor since they look very similar? |

I bought all 4 of my 20" 338's for a little less than $700. 20" Torque Thrust IIs' are between $450-$500 each.

Now if there's something out there that's similar but actually fits, speak to me! I really like the grey-centers... Not big into either chrome or glossy centers. Also if it makes any difference, the truck is tubbed in the rear. Thanks, -Tyler Posted via Mobile Device |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Here is my question, my truck is going to be a resto-mod, nowhere near fully stock, I plan to put big drilled and slotted rotors and six piston calipers on my truck, I havnt decided on a paticular set yet but I really like these 338's and I want to know if anyone knows a good brake setup to use without modifying anything, I'm also thinking about using airbag suspension, so with aftermarket brakes air bag suspension and maybe spacers what is my cheapest and easiest way to use these wheels, im not like hellbent on these so if it comes right down to it i might just get some really nice TT's and save money on brakes and suspension, any advice?

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
just machine down the hubs on the 1.25 rotors like mike said, and glue the dust cap on and your good to go. its not that hard. no spacers either. I converted mine to rear disc maybe thats why didn't need spacers.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Ok well the question now is machine it how how and does taking away that material weaken the hub?

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
I had a local machine shop do it. Is it weaker than it was? sure, but theres still plenty of material there. if it ever fails, it wont be because of that.

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
Thanks for the info, Do you remember the measurements on how much they took off and how far they went in toward the hub? Im wondering if anyone makes a rotor that is thin enough, I wont be buying the wheels or brakes for a long while so if I can buy a certain brand of brakes I'll save the money up and have my eye on what I need, if I'm wrong correct me but it looks like you've done your conversion with stock replacement parts, I plan on puttin 5 years of work into my truck at least so if i drive around on stock steel wheels for the next 7 years thats no big deal to me lol

Weaken the hub? I don't think so. I can have my mechanical engineer friends do some calculations but I be the answer is going to be no, not enough to matter. Take a look at your rotor, it's pretty beefy. |

Re: Got some new wheels: Boss 338's in 20x10 and 20x8.5
We do not have the 1" front hubs. They are the 1.25 brakes and believe me, the wheel fits right onto the hub and seats up against the flat surface that the bolts are mounted. The deal that we noted was the dust cap on the center hob pushed the center cap on the wheel out about 3/16". We did not have to force it, in any way shape or form. This whole discussion kind of confuses me, so far. Been turning wrenches for a few years, too. Need to go look some more.

I trust you know what rotors you have. I wonder which revision of wheels you have? Mine were made early last year, I think around Jan.-Feb.? I would like to know what is different about yours? I'm thinking about getting another set, the gray center this time. It would be cool if they would just bolt on. |
