depends on the amount of wear and tear they have. but, with resplining them into a new spot you can go all the way to the ground if you want. just depends on what type of ride quality you want.
take a quick look through here and see what i did with these trucks. basic 4/3 drop utilizing a b/j flip and the torsions to crank it the rest of the way up front, blocks in the rear. http://www.toyotaminis.com/forum/showthread.php?t=5784 http://www.toyotaminis.com/forum/showthread.php?t=5266
Youl go low enough to hit the bumpstop. Or your shock will bottom out. But my that time youll have no suspension...
this is with about an inch of torsion bolt left. no suspension, shocks bottomed out but scraped everything
Tires dnt look smaller than a 65 series tho, Im running 205-70s. Thats like a .125 or .25 difference i think AND HES STILL TUCKING!!!
