I went 2mph faster without it.
I'm fairly consistent in my laps and have hard data from my AIM solo to back up laps broken down by each section, so it would be easy for me to see if the GTS or GT4 aero was actually working for that matter. I'm inclined to try, but it's a big spend on parts that might do nothing. I'm not super interested in having a full, massive aero TA car at this time. Small OE-like aero also accrues less penalty points in Bimmer Challenge.

For you, if you're making the jump, the M235ir wing I think would look best. It looks more at home on this car at the taller height.
I'm genuinely curious how much faster the GT4 splitter+wing are vs the GTS splitter+wing. It's something I'd like to explore myself at some point down the road but it would be easy to make the adjustable splitter portion of the GTS lip larger than it is.

I actually think the GTS lip with a nicely extended splitter would be much MORE effective than the GT4 lip. This is because the brake duct holes are hurting the aero benefit. Any hole in the front of the car for air to go through will make the splitter less effective. BimmerWorld offers a really cool GT4-esque front lip and splitter combo without the holes. That's what I'd run if I was ready to go all out aero on this car.
The M235iR wing is kind of cool, but the uprights a bit skinny and dainty and I'm not sure I love them either. Paired with the height, it's a little off to me. I still vibe most with the smallest GT4 wing at GTS height. There are so many companies that offer this, though, and I don't know which is which. Would love it in more of a satin/matte carbon.
