What we have here are MONOPRO AND DUALTECH by HSD.
Tried and tested, we even run these on our own cars!!!
These are run on our green mk1. We run the Standard spring rates. Being compliant enough to allow alot of grip mid corner as well as soft/smooth enough to be comfortable on the road.
This is the next level of shock design. Using all the same features as the DUALTECH but with a upgraded monotube damper design. This further increases the overall strength and performance of the shock. We are currently running these on our white MK1 (Unicorn Miata).
