I'm running 225 all round on AD08R. I wouldn't go to 215 on the Integra. I've ran 215 in the past and the car felt soft and the tyres always looked flat. Stick to 225 and get some decent rubber. As above I've just changed from chunky Bridgestone RE070's and they were 225 but too heavy. I've now got 225 AD08R all round and they are much lighter and turn in is far sharper. They are awful from cold though, even worse than the Bridgestone were and the tread on the RE070's was almost semi slick. Lots of choice out there but AD08R when up to temperature are supposed to be fantastic and a great all rounder. Hope that helps!
