Built my Mardave out of the box (using a bit of my long 12th experience, I admit) and it's just down to finding tyres that work for me. One kit, one £7 spring set, one diff and it's good to go. Raced at the Club last week and was bumper to bumper with someone who had built a Supastox out of the box, fiddled with the O rings and added a diff. Not much in it in our view.
I think we'll both find subtleties in tuning the cars up - which pan car doesn't have its hidden gems that you find and keep to yourself while you're waiting for others to catch up! Pan cars are all tuned differently to suit the driver, and one person's oversteering monster is another's understeering pig!
IMHO a SupaStox is easier to build and get running for those who haven't run pan cars before, and the Mardave is the more interesting to run and race as it has more tuning options and is ride-height adjustable. You pays your money and you takes your choice...
One is not better than the other, but the GT12 class is one of the best pan car classes.
