I just replied to a different post asking "Biggest tire you can get to fit." Stock. I tried to see how my Duster's Drag race slick 30"x10.5" (actual size 29.5"x10.4") on 15 inch Weld rims line up in the wells of my street '69 GTX? And as predicted? Close, but would require some well modifications. Having drag race long lug studs? Would also present an issue getting tire on and off. This is with a Dana rear. So I can see why "Mini tub" with a 4link would be very popular. A "Full tub?" If you have the power that requires 16"+ tires? It's not a street car. Or at least has no business trying to be a street car. Our track has a class called "King street." 10.5" slick or 12.5" DOT. Racers choice. A mini tub can get a 12.5" tire to fit. Again, anything bigger? In my opinion is not street. Or over tired.
Mini tubbed to frame, Calvert Mono Springs moved in 3". 15"x12" Billet Specialties Street Lite wheels w/ 5.5" back spacing. 29"x15.0R15LT M/T Sportsman S/R tires (15" section width - 13" tread width)
THAT is a VERY NICE look!!
Back half with Alston Double Adjustables. 15x14 Weld wheels. 32" tall Hoosiers with 14" of tread. Still have room for a 15x15 wheel and bigger slicks if I want...LOL
What did you do for the rear seatbelt outboard sides?...Even though I have a cage I still want to be able to use the back seat...
If you think tubbing will get you "in trouble" you'd better not ask about traction at the launch issues with those "rubber bands" you have on the rear wheels... My sidewalls are HUGE compared to yours...
Man , that looks great, any pics of how you ran your exhaust? . I'm looking to run a stock location tank with springs inboard ,3" exhaust and mini tubbed also.
M&H cheater slick ,I think it's about 29.5 tall with a 14.5 section width.
The mini tub is fir sure easier if you dont need room for additional diameter. Heck I did a Duster along with moving the springs into the rails, metal finished in a weekend. Doug
I did move my axle back about .5 - .75 in case I wanted a taller tire down the road. Gets close at the front of the wheelwell. Slicks also tend to grow more than street tires.
Wouldn't you like to visit South Louisiana this time of year? There's a number of warm, dry blue sky days...we could mini tub my Roadrunner!
It really isn't to hard. I bought new wheeltubs when I did mine. Might be worth the money buying new inners so you wouldn't have to be so careful removing it. I will admit it was a lot tougher at 55 than 25 years of age. If you go full tubs you might have an issue with the back seats also.
I have some rust/paint issues with my trunk pan. I don't know if it warrants replacement, but if I can, I'm going to do the mini tubs and trunk pan at the same time. There was some issue with the trunk seal that I must have been able to fix without replacing the seal, it's been 7 years so I don't remember. At some point the trunk got water/moisture in it. Someone just skimmed over the rust w/bondo and painted over it.. Mini tubs are down the list, and only if I decide that I need or want more tire than I can fit.
Hi Dan, I have a fabbed Moser 8.75" rearend, a custom 21 gallon fuel tank just a little wider than the stock tank and 2.5" exhaust. Mufflers stop just in front of the axle, then the pipes go up and over and then bend outward, going through the opening between the frame and mono spring and then heading straight back. I was told it couldn't be done by a couple of muffler guys before one guy agreed to give it a shot. It's very tight but doesn't hit anywhere. 3" will be tough...
Fresh mini tubs and spring relocation. 295/65 R15s on 15x10 5.5 back space and room for a little more!
Nice set up, looks really good.
Looking good man, I’m running the moser fabbed unit too. 3” exhaust was def tight but my guys were able to snake it as well!
Mini tub no frame change, tubbed, frame change. Just remember the closer the suspension point on the rear the more body role in corners, sway bars are a must. Don’t tuck the tires too far under the car , it looks terrible imo, 14” tires are the best compromise, go for it
Think about what you want from the car long term. I knew I wanted to run multiple classes with mine. One of them had a 29.5x10.5w tire limit. The tire limit has grown over the years to a 33x10.5W which is a big tire. I still run the smaller 10.5 tire. So I mini tubbed mine. That was 20 years ago. Mine is ugly but I think you can see from this picture.
