Got my wheels Widened! mini-tub time!
Picked them up from Wheelworks in burlington saturday. I think they came out very nicely. they were 18x8's now 18x12. Now i get to make them fit.
8.5" of BS. going to be fun
----------
and after the initial sawzall attack
Im going to end up with 9.5" of clearance from the rotor to the new wheel well, and 9.25" to the closest part of the spring. Im going to have to clearance the panhard support a bit too

Keep us updated on this!
Can you post the address/phone number of the guys who did those wheels?
Can they do stock aluminum wheels?

Re: Got my wheels Widened! mini-tub time!
Wheelworks told me he couldn't do my stock crosslaces, but I don't think he understood me right. There's nothing different about widening them, than the way those were widened.

Re: Got my wheels Widened! mini-tub time!
i think he has an issue with the wheel being cast aluminum, vs billet/spun aluminum. Cast aluminum just does not weld well and is more prone to failure than billet/spun aluminum.

its a small shop, just the owner, but he does top notch work.

imagine if your axle wasnt shortened

Re: Got my wheels Widened! mini-tub time!
Well, at first he was OK with it, and said nothing about the problem of cast vs forged. All of a sudden, he decided that the 4" lip wasn't wide enough to work with , on the center of the rim......Oh well.

Re: Got my wheels Widened! mini-tub time!
That is a sick width! What size rubber goes onto a 18x12?? Are you losing the back seats to do this? I'm curious to know more.

Re: Got my wheels Widened! mini-tub time!
*edit* i just looked the 345's up and bfg has a drag radial in the 345/30/18 size to match my kdw's. and it should fit if i wanted to use it. that just badazz
Rear seats....hmmm.... well the anchor bolt hole for the seat belts on the floor went away, so to re-install belts would require a little work. The mounts for the upper seat "pins?" disappeared too. The "tub" will end right alongside the rear shock mounts, that foam thing that covers them will still remain intact. I did have to grind the mounting flange for the rear seats back part, but that mount is still there. Im going to try my best to retain the back seat. I dont even know if the interior plastics will play nicely with the tubs either.
Its one thing at a time, I need to get a 1/8" plate cut to cap off the frame and form the inner side of the tub, them i can start rebuilding the tops and side of the tub and see where the seats/plastics land.

Re: Got my wheels Widened! mini-tub time!
8.5"
I get the tires mounted tommorow, and should have the passengerside tub finished enough to get pic of the tire mounted in the car, hopefully i dont run out of mig gas right in the middle of it, im getting a bit low...

Re: Got my wheels Widened! mini-tub time!
That is awesome! I would have gone 18x12's on my wheels but with a convertible, it's really hard to do a mini tub because the space required in the trunk for the tub is used by the top.
I had to settle for 18x11's, but it does make a big difference!
Can't wait to see the final results.

Re: Got my wheels Widened! mini-tub time!
still a ways away from being finished on the passenger side, but most of the fab is done, just need to finish a lot of welding, and clearance a couple more small areas.
I did manage to get the tire bolted on this afternoon . Some teaser pics for you enjoyment.
the 335 next to the old 245
the sweet tuckage
excuse the excessive mess and dirty car
clearance from the panhard bar, needs a little work
I have 3/4" from the side of the tire to my tubs. which should be plenty. Steve Spohn says i should expect to see my offset control arms Monday or Tuesday, at that point, its drivable, but only with the passenger side started.

Sheesh, with the stock tire you could put 2 of them on 1 rim when compared to the new tire...lol

Re: Got my wheels Widened! mini-tub time!
Just curious why didn't you jus buy rims with that width, then you wouldn't have to tub your rear with the right offsets? Don't get me wrong they look sick, good luck with everything.

Re: Got my wheels Widened! mini-tub time!
awsome project but thats alot of work to maintain that back spacing, thats why we love our garages i guess i did the same thing used different back spacing but still had to remove the stock bump stops great look, oh yeah i have to admit if the car launchs hard to the right i did get a small rub 5lbs brass hammer took care of that though.

Re: Got my wheels Widened! mini-tub time!
karl's-92'-z28 - if you want to fit a 12" wide wheel, you're gonna do what he's doing. There is no backspace that will fit under the car. - yes, if he had planned to go this far from the git-go, he could have bought the wheels in a 12" width, but he'd still be doing the "mini tub" job to fit them.
2fast4u92z - it's the pic. The factory suspension class cars are running a wider section width(315/60/15) than his and they clear with the offset arms.

Re: Got my wheels Widened! mini-tub time!
also you can get any back spacing you want with american racing wheels not sure about other companies out there it cost alittle more an you can get 11.5 inches of rubber on the ground. but the 12in thing is very cool all im sayin is its very labor intence. when the car is done id love to see a pic from the rear ill post one of mine for comparison. cool project i just opted for a different lazy approach.lol

Re: Got my wheels Widened! mini-tub time!
----------
The widest i could have bought in this style is 9.5, that all centerline makes. I didnt intend to do this 4 years ago when i bought the wheels. Even if i did buy a 12" rim, it would still have the same backspacing so i would still be tubbing, unless i wanted the tire sticking 3" out past the fender

Re: Got my wheels Widened! mini-tub time!
Those wheels/tires look awesome! Definitely cooler that they're nice and tucked in too. So, I'm not fully sure what's involved in a mini-tub, are your interior pieces going to fit in after it's all done?

Re: Got my wheels Widened! mini-tub time!
Cool, pics installed please. I will be doing this mod next time I rip into the car.
I am an engineer and from that stand point that arm makes me go Wooaaah!
Those welds are going to be under a lot of shear as one tube reacs on the other.
I guess if the car doesn't have a crap load of power or super sticky tires it might not matter.
What kind of power is this car making and what is it used for?
Love the look though.

Re: Got my wheels Widened! mini-tub time!
Oh now I see.... I thought when you said "offset LCA" you meant only the billet bushings would be offset. Take would only buy you a extra like 1".
Those do scare me I wonder why they can't bend that out of one tube?
As far as money into project cars it is best not to count at all.
Cuz I think I am in the top 10 on this site with over $100,000 So that also make me the bigest loser. Or at least the poorest person now LOL.

Re: Got my wheels Widened! mini-tub time!
wow that is crazy...i also ponder why its not a 1 piece type bend. should look interesting under the car tho
i think a better bet is to fab up a new mounting point for the LCA assembly. Build a extension of the factory subframe and move the LCA mounting point inward on the car and the rearend. Therefore you dont need offset LCAs

Re: Got my wheels Widened! mini-tub time!
----------
the engine dynoed at 501hp and 520lb/ft
as for the 3 pc design, i dont see where the strength issue is. Its a relatively short piece, it faces compression forces, no twisting or anything, the welds are pretty serious, i dont see how they would break any easyer than these aluminum arms that are around or the craptastic stockers. Ive seen stock arms, rusted completely through and not broken. isnt the majority of the axles torque delivered to the torque arm anyway?
I dont know.....if they break i will be the first to know and i will report in.
I need to get more welding gas and i can start on the driver side tub

Re: Got my wheels Widened! mini-tub time!
----------
can't disclose that info, but Steve Spohn made me a great deal
you guys are sure doing a great job of not making me feel all warm and fuzzy about these things I'll just have to keep an eye on them and see how they hold up.

Re: Got my wheels Widened! mini-tub time!
i think they will handle that car just fine, especially street use. Spohn stuff is strong, and even welded like that, it will hold.
at the track they may experience a bit of twisting forces when u launch off the line, but the shocks and torque arm really eat that up.
i'm just thinking it would look "cleaner" with a one piece bend, not like a hacked welded together thing lol but its definately a trick piece and will interest alot of ppl

Re: Got my wheels Widened! mini-tub time!
The twist/traction is handled by the tq arm, the forward motion is all in the control arms. - That said, those don't scary me at your power level, the only thing I would have done differently would have been to add 4 small plates, welded top and bottom where the pipes overlapped. That would have added 4 more welds per joint to aid the shear load. For higher power you could even add a long tapered gusset(triangle) from the bushing ends to the outer edge of the offset pipe. - All in all, they're not a bad design for keeping a poly bushing. - Steve knows his stuff, I'm sure the material is heavy enough and I'm sure he welded them properly.
Really, a bend would tend to have been weaker. Once you bend a material any direction, it takes much less force to continue that bend.
Just for note, I run 17x11's with an 8" bs(4th gen rear). 315/35/17's. - There's several pics of my car floating around this forum. They're just under the upper lip, no rub issues. I rolled the wheel lip slightly and cut the corners off the bumpstops, which only contacted with the suspension at full droop(hanging on the lift).

Re: Got my wheels Widened! mini-tub time!
wow, shagwell and Orr89RocZ, the only slightly positive feedback ive gotten yet. .
I was kinda wondering, since shagwell brought it up. How much does the axle move side to side when you drop it? Im wondering if i will have to remove my tire everytime i need to drop the rear for whatever reason .
as for track use, I would probably pickup a set of bigs and little for that, and run the regular type control arms. the tires im running cost a bit more that i would want beat on at the track. Im sure i could fit a nice sized slick back in there.

Re: Got my wheels Widened! mini-tub time!
this is where i think some people are missing a little. The poly bushing side is one thing, i could gusset it up on the sides like that. I still have the clearance the floor a bit near the body mount so the offset does not hit the floor. On the axle side, with the rod end, the offset tube is real close to the coil-over setup and the adjuster ****, i will have to get a pic, but this arm is made to fit tightly in a really tight area and the dimensions we not just arbitrarily chosen, i mean, the arm sits INSIDE the wheel on the axle side.

Re: Got my wheels Widened! mini-tub time!
[QUOTE=//<86TA>\\;3630304]wow, shagwell and Orr89RocZ, the only slightly positive feedback ive gotten yet.
i was only asking the price as i might be interested in a set in the future.
i emailed steve and he said he is going to manufacture future sets and sell them for 295.00+shipping.
i guess he gave you a deal, and didnt realize the extra amount of work put into the arm.
as shagwell said, id have them plated or gussetted for higher power, but you are never gonna hurt them, unless weld penetration wasnt good. it would only then fail from fatigue of time and time again of abuse.
you arent going to hit the gas and go around the corner and them break on a maiden voyage.

Re: Got my wheels Widened! mini-tub time!
As for the extra work involved in the fitment, I told steve i was mini-tubbing the car to make the wheels fit, and anybody with a tapemeasure can figure that you need more than a hammer to make room. And they probably wont work with regular coil springs either.
In the end they are just pieces in a larger puzzle.
I guess its not a big deal, I dont think Steve will hunt me down and take me head for spilling the beans. I paid just under 200 for the set, which is a great price for a 1-off set of arms.

Re: Got my wheels Widened! mini-tub time!
as far as side to side movement, i dont think it will move that much. the panhard bar controls that. the way the shocks and lca's are bolted on the rear, as well as the dirveshaft and torque arm, its not suppose to move side to side.
i dropped my rear many times and dont recall much movement.

The panhard isn't supposed to control side to side. It controls pinion angle. The panhard is what controls side to side,
