xgolferdude, if it's not bodydropped yes, they should tuck.

to use a smaller booster is easy jus use a mazda GLC rear wheel drive 1978-1980 model which bolts straight
into the factory holes & is only 7" diameter instead of 9" ill get some pics up of mine
it ran 20x8.5 235/35/20 with 3" bd & 4wd sheetmetal
