Doug,
I've got the product info on Air Ride, Ground Force, and some ideas on wheels - I'll try to post tonight.
Scott is right about the changes on some of these trucks - several at SEMA had been changed to 5 bolt axles, front and rear - out of range for most of us.
As far as wheels, very little on the market to work on the SSR - different sizes, offsets, and the Trailblazer bolt pattern, so the selection available for full size GM doesn't work.
Coddington, Budnik and Bonspeed were not at SEMA, and neat wheels like the Foose Lusso and Speedster don't have the right bolt patterns, or offsets. Most manufacturers and going after the bread and butter business, and the SSR just doesn't have the numbers to justify the investment in tooling.
That's where the billet guys come in - it's pretty well all custom work, but you can expect to be in the $900 range for a 19 or 20", and possibly $1200 for a 22".
Check coloradocustom.com to see the selection available from them. The one I liked was being introduced at SEMA, so not on the website. (Photo attached) Most of their wheels are built to order, so in those cases, diameter, offset, and bolt pattern can be ordered as needed. They were very easy to talk to at SEMA, and their website has instructions on how to measure backspacing, caliper clearance, etc.
I probably won't be doing anything right away - I'd like to sell the 03, and free up the funds to build a house, then get a 6 speed 06 next fall. If the 03 doesn't go at a reasonable price, I'll hang on to it, and start some mods for next spring.
