Shocks don't really do much for body lean, not their job.

With the tires you're running, you will be limited in performance anyway so I wouldn't suggest Bilsteins.

Firmfeel sells bigger torsion bars and front/rear sway bars. But nothing is cheap, you could easily exceed the purchase price of the Doba with just new T bars, sway bars and Bilsteins. But with those the handling is done (except for better tires).
