DC5 is the chassis code for the RSX/Honda Integra 2002+. DC2 is the chassis code for the Integra 94-01, DC4 is the chassis code for the Integra 94-01 with a B18B engine.

The chassis code is the code for the physical skeleton of the car, the metal unibody welded together to form the vehicle's structure.


The A-Spec kit includes a body kit (front lip, rear lip, side skirts, high wing), different 17" rims with performance tires (I forget which but I think they're Yokohamas), 1 inch lower springs and modified struts both of which were designed by the NSX Nurburgring team, A-Spec badging, titanium interior trim kit, and I think that's it. Its not worth it. Its a better value to get everything aftermarket, the suspension is a good piece though, some dealers sell just the A-Spec suspension on eBay.
