I have done some searching on the Shigspeed setup and other coilover setups, and I haven't been able to find any pics or real info on them. My question is, what exactly is it that makes these particular setups different than say, a system similar to Ground Control's? Is the shock body itself threaded? If it is, how do you use inserts like the Shigspeed setup? Is it possible for me to fabricate my own setup? I can make anything I could need without problem, but is it something you need special equipment to make? Thanks.
