I basicly use the stock tcs rebuild as a back up spare now. The stock rebuild seems to fade on some of the long races I do, although I like the way it performs until it just gets too hot. I keep switching back and forth between the stock link set up and the elka link set up. Think I might be finally leaning more toward the elka link set up even though it tends to bottom out more, the elka link actually increase the amount of up travel you have too. I've been haveing problems with one of my elka shocks and its been making things difficult to decide which feels better the stock or elka link due to the elka shock I have set up for the stock link not working properly. When its time for my shocks to be rebuilt I send them to TCS/Race Tech, elka's included. Except for the elka i have been having problems with it was still under warranty, although it cost me over $100.00 to send it to them due to some kind of b.s. brokerage fees.
