Axle shortening

[Silverhatch]

What is the point of shortening the rear when minitubbing? Are there no wheels available with enough backspace? Does a deeper rim interfere with brake lines etc.?( on initial inspection on my car, it doesn't look to be a major obstacle).

I think shorter axle tubes have less deflection. Also, I believe less backspacing helps plant the tires better.

shorter axles will be stronger too ?

I agree with the above but I think its mainly for wheel selection. You minitub to run a wider wheel/tire and most of the wide wheels commonly have less BS.
I just put 12" wheels with 7.5" BS on my car and luckily they were available with that BS, most have a max of 6" range in that size.

So, you didn't shorten the rearend? What lca are you using?

[biminiLX]

Rear was shortened 1.5" per side from standard Fox width.
Used to have 15x10" 6.5" BS wheels with stock rear, changed to 15x10" 5.5" after I shortened the rear and then just went to the 12" with the 2" added to the BS for 7.5".
Bill, call me whenever today.

so 1.5 " off the rear is a good amount ?

go with 2.5, you may like better

i ment per side ? just to clearify

[biminiLX]

We did 1.5" on mine to try and keep the 6.5" BS wheels I had but when it was done they looked too set-in so I went with 5.5" BS.
I really think shortening EACH side from 1.5-3" does what you want and will keep you in the range of most common wheel sizes.
I wanted mine to sit real close to the flush on the fender, I like how it turned out:




I gotta get some pics of the new 12" wheels and 315/60/15 DRs mounted on the car up at Street Lethal.
