No idea on how much downforce, but I'm somewhere between 3200 and 3300lbs with me and half a tank of gas in the car- Casey had it weigh in at 3315lbs when he did my corner balance, but the car has lost some weight since then (and it was done with the stock 19s on the car, not my apexs)

Too much back-pressure from the prototype exhaust I had on.

I swapped exhaust the day before I was going to take it in to get looked at, and figured why not clear the codes and give it a shot. It pulled all the way to redline and didn't throw any codes. I've tracked it 2-3 times since then and zero issues.

Were there any other problems with too much backpressure? Any engine damage or harm?

Not that I know of. My friend that is a bmw master tech thought I bent a valve or something, which was causing the error code, but there is no way of knowing unless we take the engine apart. Considering the car is running great now with no issues, I don't see myself taking it apart until I do rod bearings.

I'll let you know if anything shows up in the future

Could have sworn I replied earlier but just noticed I didn't.

Casey at Racewerkz had a lot of stuff left over from their shop car. The lexan windows, carbon doors, SPL components, differential, and rear wing are all from that car

Would you mind posting some photos of how the swan neck uprights are mounted in the trunk?

Thanks!

Suspension update: I swapped out the front springs a few months ago for shorter Swift springs.

Feels great to be able to run wider tires now. For anyone with the perch issue, like on KWs, I would definitely recommend this for the peace of mind. Pic attached is 305/645/18 Pirelli DH on 18x10et25 with NO SPACER

This is a lot of questions, but what length spring and spring rate, do you still have the KW helper spring setup, and do you have photos of the ride height?

I'm still trying to figure out what specs to use for my KW CS setup, which currently has the 110n/mm stock KW setup.

I did the Eibach spring conversion that is mentioned on a few threads. It’s probably the best “easy button” option to the wheel clearance dilemma.

6 inch spring (down from 7), I'm pretty sure the spring rate is 728lbs, never had a helper spring, and I'll upload a ride height pic when I get her ready for the track tomorrow. Raised both front and rear a little after doing the spring swap
