I've got rear spacers on and don't reckon it has improved the handing much to be honest, although I don't drive it really fast round corners but it does look better coz it's lowered on coilovers. A rally driver said to me why would seat not just increase the rear axle a little if it's gonna make the handing better? They're said thousands of pounds to design the car so surely that axle length is the best? I just thought they were for looks.
