better shocks and springs front sway bar is 24mm (same as the gsr but read on) rear sway bar on itr is 22mm (gsr one is only 15mm) the rear lower control arms are designed to deflect in a desireable (alignment way) while corning the bushings on the car are a hard rubber that is stiffer than normal bushings comes with a stiffer rear subframe a lower rear chasis brace a front upper and front lower chasis brace a trunk braceand lsd along with Bridgestone Potenza RE 010. Very well balanced car and actually handles compared to other front wheel drive cars. If you turn the steering wheel in this car at speed the car actually turns instead of continuing to go straight. It is a very easy car to get to do what you want it to do. The front brakes are 11.1 up front compared to other integras which are 10.3. The rear disc on the type r are also larger than hte other integras but cant remember the diameter. The head has been mildly hand ported better cams better valvesprings better pistons. Overall a very nice smooth well handling car even comes with Recaros.
