Basically what I am looking for is just shocks. Tein and Ohlins might make shocks but Teins are not the highest quality and for Ohlins you are looking at $2,000 for a set of custom shocks. I need to run stock springs, so there can be no coil overs. Both the Koni and the Bilstein are revalvable. The Koni is adjustable already. I don't have the budget for Koni 2800 series shocks which are essentially old Formula One technology with aluminum bodies and such.
