Shock/Spring kits arrived from GTS Racing. Very nicely made and tuned for the Locost specifically. The front one is the longer of the two and uses an 8 inch, 275 lbf/in spring. The rear is a 7 inch, 175 lbf/in spring. They have adjustable spring seats for ride height adjustment too and were only £220 including VAT for the set. The bushes require 1/2 inch UNF bolts.
