Gentlemen, these Progress coilovers are simply kick-ass. I have never read a bad thing about the product. One person had an issue with service, and more than a few folks did not like the wait-time for the product. Other than that? Rave reviews.

A very high quality, off the shelf, coilover system. Workable as a daily driver, excellent for auto-cross or road racing. It comes pre-set up from the factory, damping is non-adjustable. Bolt it on and go. Very quickly.

To that end, we contributed our SE-R and our calibrated asses to a several-monthlong development process that resulted in a truly amazing suspension.
There's nothing particularly special about how Progress coil-overs are made. They're heavy steel with internals you might find in an O.E. shock. But it isn't fancy parts that make a suspension good, it's the tuning. After several iterations, the Progress coil-overs are tuned for an amazing balance of ride quality and ridiculous handling.

These two quotes sum up the "adjustability" or "no adjustability" discussion:

I know that I don't have the lap time and stuff to make adjustments and re-run/make adjustments again/re-run/make sway bar adjustment/re-run and so on before an event. I am a noob to racing though, so who knows? I like the progress setup because they work damn well, price is good, quality is great! Brent

You just have to like the way Jared and I are going to set up the damping and spring rates.
MSRP: $1,499.00
Per Progress sales staff: Yes, these are compatible with the Ground Control camber plates. There is hardware available from Progress to make them copasetic.

That means you are
literally buying a product "preset-up" by Mike Kojima and "Jared" (Holstien maybe from SCC?)
And GregV is a great seller. Just did business with him recently, I just haven't done the excellent feedback thing. He took very good care of me and my order.
Free bump for Greg.
