2 things I've noticed 1. take the front strut brace off and drive it you can feel the difference in stiffness and 2. my new gt has 50 profile tyres on it so cant wind the coilovers as far down as on the black gt which had 45;s. them few inches higher makes a lot of difference it doesnt feel as planted just goes to show that a little difference can completely change the rigidity of your car lol
