Unfortunately we are unable to bring the full car back to RD by request of its owner, but for those of you who downloaded it during the year or so it was available and still have it, here's a physics update to bring everything in line with modern AC and the NFS cars. Also included is a CSP extension file courtesy of @AlleyViper . Files are included for both the base model Boss 302 Laguna Seca and the HPE650 step version.

Physics changes aren't dramatic, but adjustments and refinements have been made to dampers, bumpstops, ARBs, brakes, inertia, tires, fuel consumption, autoshift timings and AI. (And possibly some other odd stuff.)

To install, simply copy the contents of this zip file into your cars folder. If you want to keep your old data.acd files, don't forget to rename them first.
