When did everybody start talking in kg/mm instead of pounds, for goodness sake?

Geez.

A celebrated combination for a DC2 is Ground Control with 400# F and 500# R, together with Bilsteins. Don't drop the ride height too much. Just bring it down to ITR level or maybe 1/2 inch lower...that's all.

If you want something longer term or you think you're going to end up racing, then go with Koni Yellow but know that you'll have to revalve them at some point in the future if your spring rates go up.

The suspension dynamics of the DC2, IMHO, require the heavy springs in the rear unless you are prepared to go the JDM route with camber kits and a heavy bar in the rear. IMHO, it's just cheaper to put the heavy springs in the rear to start with.

What's this car going to be used for?
