Moving up to Street Prepared worth it?

[LAP1DOUG]

STU used to be for sport sedans until they let the C5 Corvette into STU. Otherwise STR and STU are basically the same prep except for allowable tire widths.

For stock (street), but I believe you will need to change back to the stock seats.

Original proposals for Street class allowed camber plates until SCCA figured out the P cars and BMW's would then be competitive. Then suddenly that allowance vanished.

Not sure you can win without fixing the poor front camber situation with these cars. Good luck
