The "deep lip" on the wheel won't change with a minitub. It's determined by your axle width. The minitub will let you run a larger tire, though.

I did it and it was a lot of work for me. It took me several weekends to finish but I know a guy who did it in one weekend. My car is finished and I don't think it's all that visible of a mod and wouldn't do it again if I did another car. Too much work and doesn't get that much notice. It does allow a 315 size tire though if that's what you're after.

My question is; Is rust an issue? If you have to replace some metal back there to begin with,I'd go for it but if it's solid ,and I didn't REALLY need bigger tire size,I wouldn't do it JMO.

With a 56-7/8" axle and a 10" rim, you're just about on the limit of truly needing a mini-tub. If you don't, you're going to need a shallow backspace wheel and it's going to have to be precisely measured and spec'd for you to run even a 275 wide tire. But you could do it. You would be limited to the 275 tire, which is really too narrow for a 10" rim.

You gain only 3/4" per side by doing a pocket kit. You can gain 2-1/4" per side, putting the tubs right against the frame, if you tub AND do the pocket kit. The bonus is you won't have any problems with tire to fender or tire to tub clearance until you get to a 335 or so tire width if you do the backspacing correctly.

Doing a mini tub is not as difficult as it is time consuming, especially if you want to finish it to look like it was made that way.

I did a mini-tub on mine using a pocket kit, a 58-1/2" axle, 8-1/2" rims with 4-3/4" backspacing, and 275 tires, and I have no regrets. I could put a 315 or 335 tire in there if I wanted.

IM IN THE PROCESS OF DOING ONE RIGHT NOW, SLOW GOING AT IT, TO ME ITS A NO BRAINER IF YA DO THE SPRING POCKET KIT AND NOT DO MINI TUB U DO NOT GAIN MUCH. ITS NOT THAT HARD ITS A LOT OF LABOR AND TIME CONSUMING WELDING & GRINDING TO ME ITS WORTH THE TIME FOR THE SIZE TIRE JMO

It was a lot more work than I thought it would be, but now that it's done I'm glad I did it.

Lots of room for big tires.

:happy0030: I recently finished installing air rides 4 link and mini tubbed on my own. First one and it took quite some time for me. Mounted some MT 315/60/15's and MAN WAS I STOKED! To see the car with a 13.9" section width looks toooooooo Bitchin! and it's gonna grab the road. Worth the work for sure.:tu

I never regret the mini tub..with a 11" deep dish wheel / 345 tire the housing was 50-1/4" disc to disc:)

Very similar to my 55s combo, 56 inch Dana 60, 8.5 Torque Thrust 3.75 BS, 275/60/15BFGs and I like it. It is easy to get tires on and off and no rub issues.

If I wanted wider tires I'd just TUB it narrow the frame and geter done. I run M/Ts on my 57, 12" wide no tub usind back space but radiused wheel wells. My nova has 29x15.5x15 I tubed that and if I chose I can go wider

Like what has been already said, a big, time consuming job but well worth it.
Just make sure you've got a decent welder, i did mine with a cheap mini mig and it was **** but now i'm going to get something decent to put the 4 link kit in.
I went with 15x10 and 29 x 12.5 Hoosiers and i love the way it looks now with heaps of room to spare aswell.

To mini or not.....

Hi - If you are apart already and have the pocket kit installed then it is absolutely the right time to do the mini tub. It is a fair amount of metal working to get it nice, but well worth the effort..!!! I'm running Mickey T's 30X12.00R15LT that have 10+ inches of tread on the road with 10 inch wheels and 6 inch deep reverse. They are 12 inch wide at sidewall and I still have a bit of room to go bigger if I want to. You cant get that look without the minitub..!! Good Luck

JMHO.....DK
