Game keeps crashing when trying to 'live tune' or change speed card!

Thanks for your reply. I've re-installed the game several times now and rebuilt my PS4 database, this helped resolve most of the game crashes and freezes however I still have a number of cars that I can't live tune or update. I have noticed a connection, it only seems to be the cars that have the deluxe game version platinum underglow or tyre smoke applied. Unfortunately I can't uninstall the items as the game crashes but I can sell the cars as a whole, which I have done, and then re-buy, modify and upgrade to solve the problem. I just don't use the Platinum items anymore. Anyway, just thought I'd let you know. Thanks once again!
