How much will a 27×10.5 slick grow?

Thanks, I had not taken into account the rear squatting on launch. Nor had I thought about just lifting the rear up to fit a taller tire.

I may just put my spring sliders on 2x3 stock to make up for the loss of shackles.

I like the rake I have and was kinda bumbed to loose it whit the lower height of the sliders.

Thanks again for all the help and advice.

If you are running leaf springs it should not squat when you leave the starting line. Leaf spring cars rise in the back at the hit.
