Frequently Asked Questions:

Whats the biggest wheel and tire i can fit after installing a mini-tub and spring relocation?

Its hard to give sizes that are concrete due to the shape of the wheelhouse, ride height, and wheelbase. You will have 15" clearance between the frame and the outer quarter panel lip in the center of the tire. You can even roll the lip for more room, but 15" is an enormous amount of room. When our mini-tub kit is installed with our rear spring relocation kit, this will allow for maximum tire size. The actual size tire that can be fit in the wheelhouse will depend on many factors including wheelhouse shape, size, ride height of vehicle, wheel backspace, wheel diameter, tire diameter, tire width, axle width. All these play an important part in selecting the correct size for your application.

Examples of tire size and wheel combinations we have used on E-bodies:

1971 Plymouth Cuda: 355x30x19 Tire

Does the rear end need to be shortened?

The rear may need to be shortened depending on your wheel offset, this will require mock-up and measuring to be correct.

Will the rear seat still fit?

The rear seat may need modification along with the inner quarter window interior panel.

Do the seat belts still work?

The outboard seat belt anchor will move inboard with the inner wheelhouse and the seat belts will continue to work.

Does this require different shock?

If you narrow the rear, the shocks would ideally need to be shorter and will also depend on ride height, so mock up and measurement is required to get the right length.

Do you install these for customers?

Yes we do, just give us a call to schedule an installation appointment.

How much work is required for the install?

We allow 4 days to perform a complete mini tub installation in our install center.
