Function/Form are cheaper if you buy them directly from the dealer. They aren't bad.

Even at that price point you could get what I have, progress CS-II.

Made by a company who holds records in SCCA. They do TONS of in house RND, and unlike the Function/form you have multiple options for spring rates. Replacement shocks are like $63 directly from Progress Auto if one blows out of the warranty. If you want to change the spring-rate new springs cost $90 shipped.

Bisimoto uses their products. That should be enough, lol.

They aren't flashy, but they have a solid company with tons of Research and Development and knowledgeable racers working at their facility. They even produce a sway bar with special mounting brackets for 96-00 civics so that you don't need an expensive ASR brace. Been using mine for 3 months and no problems.
