I just received my RSC diffuser today. I was on the fence between EOS and RSC but happy with my choice. I bought some EOS boomerang and sideview mirror overlays and they were very nice with great fitment. But the RSC is on another level. Packaged so well, beautiful finish, and the surprising bit was a vanilla envelope with a folder inside containing a receipt, certificate of authenticity, and heavy duty instructions printed on card stock.
As promised…….pics. I took a couple to specifically show clearance on a stock ride height car. At first service, I’m having them lower it 1/2 to 3/4” though.
I’m the one considering the ZR1 wing. If it becomes an option you can buy from factory, I’ll feel better and pick one up from RSC. My thought is….it’s like BMW owners putting M badges on their run of the mill 330i. jmo
I just ordered the wicker bill extensions for mine. And I’ll probably order more once I figure out which direction I want to go.
I called them on the phone earlier with questions and the customer service was great. They spent a lot of time with me answering all my questions and didn’t rush me off the phone.
That diffuser is mean! Can’t wait to see pics after you get it installed.
Same on the call! TJ spent lots of time giving me a couple extra tips on the install. Amazing customer service.
I have a bunch of their stuff and everything has been perfect with no modifications needed to install. TJ is awesome. He can also drive man don't race him on go-carts he's a legit driver.

Will post pics after installed.
I like the RSC and the EOS the most for the designs. RSC is the best you can get so you did good. Is your car lowered? Been wanting to see what it looks like on a non lowered car.

Not lowered. Had to buy the 5pt torx security bit for the wing (which arrrived this morning via Amazon). Going to install it today. Will take pics.
Rsc quality is amazing! I bought higher wing stansions for the Z07 wing. Even the packaging shows how high quality this company is. The carbon fibre wing stands are made really nice. Only problem i had was after removing wing from car, I could not get stansions off wing. There are screws inside stansions that are easy to remove, but Gm also used a grey epoxy. Had to heat the crap out of them and pry them to get them to pop off. Then grind down the epoxy to get the new stands to sit right. Very happy with how it turned out. Wing is maybee two inches higher than stock.
Diffuser is on and fitment looks OE. Gaps are spot on and install was easy thanks to the comprehensive instructions. It's dark now so will post pics tomorrow when it's light out. I'm seriously considering a ZR1 wing but am torn. I don't like the Z07 high wing and want something different. I like the ZR1 wing, but I don't have a ZR1 and feel like I may be trying to emulate a car I don't have. We'll see......

I agree with your assessment about feeling like a poser with a ZR1 wing but no ZR1…. Now I’m not saying not to get it that’s completely up to you but I understand your position about getting it.
@S3ND17 Did you already have Z07 aero from the factory? If not. Then I would go ahead and get the ZR1 style wing. Why not? its not the OEM so its not a copy, and who cares what others think. This is for your cusom build. Once you do that. Just keep in mind that you will want to change out all the carbon fiber on the car to match so RSC will be getting more of your money.

Looks great! Did you have to remove the bumper to install?
Yup, but RSC includes fantastic instructions with photos of every step. It’s really quite simple. Just need two sets of hands to help hold it when pulling it on/off and disconnecting/reconnecting the electrical connections.

Cool, I need to take it off for other bits anyway.
