Need some help with making some aero decisions

[OCONNOR394]

Im planning on essentially replicating the aero from the E92 M3 GTS as ive found i need a bit more rear end grip on the fast sweeping corners. I've found a GTS rear wing, still trying to find an oem GTS splitter. I've gone for this setup as in australia the legality of rear wings is very strict and essentially the GTS wing is the only legal one I can put on if I want to drive it on the road frequently.

My main question is will this setup produce even a small amount of downforce and if so will the GTS lip be enough to balance out said downforce. I'm assuming yes as it will essentially be a copy of the GTS car. if the GTS splitter isnt enough what other splitters would you guys recommend that arent to big.

this is discussed in pretty good detail in this thread. if there is anything beyond this, just ask.

Have you considered paying for some aero consulting with CFD analysis? It's what I had to do since the front splitter selection was so poor, and no one was making matching rear wings to maintain aero balance. Generating downforce at the front of the car is a lot harder than at the rear, as I understand it.

Also, there are ways to generate more downforce besides splitters and wings...like underbody diffusers.
