"?Curious as to what brand of shocks people are using, and the settings, on the rear of your Spitfire Race Cars?" I'm running SPAX shocks in my 63 Spit 3 or 4 clicks softer than the front shocks. I've had SPAX shocks break the ends off from off roading and impact but not leak. They've behaved on my street Spits/GT6 too. mike h
