Ride quality even worse than expected. Advice welcome.

My son's Barracuda has 1.14" torsion bars, big sway bar front, 3/4" bar out back, heavy rear springs (cobbled up at home), short bump stops, and KYB shocks. It also has 235-60-15 tires on all four corners. Ride is great, even on bad roads. Last time I rode in the car it felt great. The tires probably do a lot to help the ride characteristics. This is also with an all-iron (except for the intake) 383 and four speed. I don't think his Barracuda rides as stiff as my 2004 330Ci with sport suspension. Then again, the BMW has extremely short sidewall tires.
