My Crossfire is a 2005 base model. I have installed K&N air filters, H&R 30mm front anti-sway bar, 17x7.5 front Sparco rims, 18x9 Sparco rear rims, 225/45 Bridgestone Potenza RE71 front tires, 255/40 Bridgestone Potenza RE71 rear tires, custom cat back, and Koni Sport shocks. It's a manual transmission. I purchased the base model because it's lighter and has fewer frills.
