I remember hearing somewhere the euro x308 hand stiffer suspension than US. Is this true? I just went to test drive on 02 xj8 sport and absolutely loved it, except for the suspension, far too soft. I noticed this in a straight line, I wasn't even cornering. Lowering isn't an option because I plan on fitting 20's. I'm this close to buying it and getting rid of my xk8. Definitely would go with bilstein heavy duty shocks. Is there an option an option to stiffen up the suspension without lowering?
