I don't know this is a better solution for those who cannot get in touch with the Serpent shock tower as a replacement........you can buy 2 3racings shock towers from EBAY/DINBALL.........I think for the price of 2, is a little bit less then one stock tower from Serpent (I believed they are $40 from Serpent each)....
On top of that..........you can pick the SSG version for ALL SHOW and NO GO route. I usually won't recomment 3rd market parts for Serpent, but shock towers is not something that important, also, the price of 2 to 1, it is a bargain.
What is odd is....they have only 2 shock positions....why? and what happened to the rest?
