Congratulations on the new driver! That's a nice looking car.
IMO...I'd keep the wheels and the ride height. Ditching the Lean Burn, especially if it is a acting up, is a must. If not, you can plan that as a future upgrade.
I'd second the vote for some immediate repairs to the trunk floor/rear frame rails.
