It’s made for this Roush chin spoiler.

I understand how LVA shapes their splitters and that the Roush splitter is for that part. With how small the part I received was I'm thinking that it was actually for an OEM bumper and that the seller was mistaken.

I love the splitter bracket, keep in mind anything up front needs to be addressed at the rear of the car also.Did you get rid of those press in spacers? Because they really need to go. I'm surprised you didn't get busted at tech with them.

My car has the raised wing that was apparently an option in 2011. My understanding is that the Boss 302 Laguna Seca cars have the same wing with a splitter, so I should be fine without changing anything back there. While I do want to improve my aerodynamics as much as possible, the addition of a splitter is mostly to protect the bumper from cones that tend to jump out in front of me all the time.

I'm assuming that you are referring to the wheel spacers with pressed-in studs - no, I have not changed those out yet. I have brought them up every time that I've gone through tech (mostly autocross but one track day) and nobody has had an issue with them. I check them every time I rotate my wheels (typically every other event) and haven't ever had a loose nut. I can't speak for the Time Trials rules, but there isn't anything in SCCA's Autocross rules saying that I can't use them. Are they the best option? No, probably not. Are they wrong? Also no. However, they are still on my list of things to change.
