Resurrecting thread to correct Misinformation. Just because the S 197 is stronger than previous models does not mean that it cannot benefit from subframe connectors. The first thing a race team does with the chassis is seam weld it. If it was so strong why would they bother? Chassis stiffness is key to handling and it really cannot be too stiff and compared to german cars our chassis are marshmallows. Who cares if a guy runs in the 9's without them. You can't say he would not be faster with them. Stiffler makes subframe connectors that are less than 40lbs. Well worth the weight.
