Ok I got bored with FCR NASCAR sorry guys but being a true blooded Parma parts user and believing in there C.O. I hope this will catch on.... Take a look at the Parma FCR pan I came up with. I call it Parma retro.
Taking the FCR pan modding it to fit retro F1 Truescale, O/S body F1 and many others it works great.
All parts from org. FCR Pan. Wheels cut down so clearance is 1/16 under pan to track makes this little bugger scream around the track.
