i was wondering how exactly the RS (Y3F) Camaro 3 piece spoiler attaches to the car? i am going to be installing one within the next couple weeks so any information is helpful.

 

For the center section I think there is two studs at either end and one in the middle behind the brakelight. The two ends have three studs a piece and those use special speednuts with sealant on them. The spoiler is also held on by double sided tape. Now this is the factory one so I wouldn't know about a rk sport replica or any other aftermarket one.
