WEll, I did this amp install the other day on a Corolla XRS. I was poking around the car after the install and found this car has very similar underpinnings as the xA and xB. Matter of fact, the rear axle is the same except the XRS has a coilover setup like the tC. With this in mind, I began to wonder if the engine(2ZZ-GE) would fit too. This would get us a buck 70 in HP AND a six speed. As for the brakes, This car had giant front rotors. They barely fit inside the stock 16 inch wheel. Any feedback on this matter?
