You know the ones...KW Suspension, Belltech, ST Suspensions, as seen on most of the GTR3 cars. ...the ones that have been available to race against for many months yet cannot be purchased? How about giving these away for free to anyone who owns the relevant cars? A bit of good will and free advertising. Just an idea.
I think some of them were awards for taking part in competition. I for sure can recall Fanatec BMW M3 GT2 and KW Suspensions Corvette GT3.
