May seem strange, but bear with me......
Building a little autoX car known as a Seven, or a locost. Mine will be about 150bhp (to start) and 1300lbs. Some guys use bike engines in them even (if they get the weight down). Turbo busas are popular.
What I am after, is a pair of common (IE cheap and plentiful) bike coilovers, 350-500lbs/inch, has a common spring so replacement is easy. Id pay more to get dual adjustable shocks though. Mounting shouldn't be an issue as they are inboard shocks (pushrod with rocker arm).
I am wondering what the best OEM bike to look for these from would be? Do smaller displacement bikes tend to have softer rear springs?
Thanks for any help guys.
