i heard Suspension Techniques are good...any other good, reputable, companies?

 

tanabe just came out with the rear sway bar i think.

 

Leave the front stock and upgrade the rear with a ST.

 

Neuspeed, Eibach, and Progress Technology also make sway bars for these cars.

Mugen did at one time, but you'd probably be lucky to find a used set now.

Saner Performance, a company that does custom/semi-custom bars, has already done a 1" rear.
