Hi, I have been running this Ultra wide set up front and back for about 6 years. On the Track I find the car can carry a higher corner speed especially at the Apex. Cooler front tyre temps, able to run a softer compound. On the road I have not noticed much different from STD set up. Not that I cover many road miles. The Quantum dampers have made a big difference to feel of the front end. Down side has been replacing the damaged parts. They are not off the shelf so take 2 ish weeks to have them remade. Merrick69
