what dia t bars should I buy? & what shocks should I get?

1.14 torsion bars, hotchkis shocks.

Chassis connectors and torque boxes help HEAPS!!

And a sway bar...definitely.

I have 1.14" bars in my Duster and I'd say they're a bit much if the OP isn't trying to hit the track or do serious canyon-carving AND he'd need some wide low-profile performance tires in the front to take advantage of them anyway over smaller bars. IMO he's probably better off with 1.03-1.08" for something more street-oriented.

I second the 1.03" bars and Bilstein shocks along with sway bars.
