If the wheels don't fit inside the wheel well, then it's a ******* farce. Jacking the body off the axle is illogical. On my 68 post Coro, I had 15 X 10 w/ L 50's on back with stock rear end geometry & the tires were snuggly inside wells. On front were 14 X 10 w/ 225 HR T/A's so it was a healthy nosedive, but didn't muck up the handling,, *** end was very predictable & forgiving, the car ripped it up on the corners, due in large part to being small block.
Yes, I ran the Goodrich radials in front, & the bias plies in back, but didn't have the twitchiness so often the result of radial front/bias rear because the fronts were very low profile & the wheels were wider than tires, which really stiffened the sidewalls.
