LOLL "pretty multi-vented yellow Boxster". Danger com'onnnn you have to admit this is a good one mate
OP - RE the rear spoiler. They are used for high speed cornering. If I were you, I'd do a Before & After trial at your nearest circuit before tossing it away. Those spoiler provide amazing downforce if I am correct. The one you have is a generic spoiler and fit any car. However it is shaped as it was designed by a serious performance professional. Drop by the circuit during the next open track day and bring it over to the car guys. Some there pays very good money for those
And avoid posting anything other than sporty show-off Bling Blings on 986forum in the future
Otherwise it creates problems
