JB1

I'm by no means an expert, but I'll give it a try. The wheelbase of the 370z is relatively shorth and for it's size, it's not a particularly light car. So to keep body roll in check, the suspention has to be rather stiff. Stiff suspention combined with short wheelbase make for a jumpy ride over un even pavement. I only had my car for a week but already experienced the backside stepping out on a bumpy
highway onramp. I had a friend who owned several lotuses ( or Loti as he would say) and I had the pleasure of trying them all: old Esprit Turbos, Excel, Elise S1, Elise S2. All these cars felt more comfortable and less "jumpy" then the 370Z. I am convinced this is due to the fact that all these cars are significantly lighter then the Z. And therefore could "get away with" a relatively softer suspention set-up.
