Amazing Build!

Very nice build. I was looking at the AP Motorsport GT4 front splitter, Im now aware of this other option from Slon and the extra work required. Thank you very much.

Do you by chance have a part number for the GT4 radiator mounts required to fit the splitter?

I do, however I ordered them from everywhere online I could find and nobody was able to source them, so best of luck! Ended up modifying a standard set.

17-11-8-431-150 Bracket Oilcooler Right 9100000F82

This looks great. What spring rates did you pair up with the additional aero? Any issues at full compression?

Whats the latest on this...is that front splitter stret friendly at all? I feel this would get torn the fawk while slammed on 18s.

Thanks man, sorry for the delay. I increased them to 11k/16k and haven't had any issues at full compression. I may have gone stiffer but would have required a re-valve so I only increased them as much as KW said would be ok for stock valving.

Still running strong! Don't really drive it on the street though haha, only to/from the track. When I do take it around town I am pretty careful since it'll scrape just about all driveways even at an angle and I'm fairly paranoid I'll hit a dip or pothole that will destroy it. I put slip-lo strips on the leading edge to try to help it slide over driveways without scrapping up the carbon but if they catch an edge (like a sidewalk seam) they come right off. Keep in mind I'm also not that slammed, ideally I would run a bit lower on the 18's but I'm fine trading off some performance for a bit of clearance.

As mentioned they still need some adjustments but functionally they worked great together, much better balance in the high speed double apex's of Chuckwalla where under steer is normally very prevalent. Plus got a great response from all of my Bimmer Challenge buds in the paddock!

Did you buy a new trunk to install that wing?

Yep of course. Normal M4 trunk is exactly the same, just had to cut the holes for the uprights.
