Lap time details

rollercoaster of emotions in this weekend . many things happened . very bad and very good.
I'm rusty. made mistakes ( huge one in t6) but fuxx it is good to be back racing!
many 1:20 predicted so it is doable.
Car still need lots of adjustments.
35mph headwind didn't help but the car is really draggy now. I might lower the aero next time. we will see . enjoy!

I saw 1.93 sustained G's in that right hander.. man that car is a grip king!

what specific parts made it the most draggy and tell me about that sweet front splitter.. dissecting your build thread today.

I need to update the builf thread. I'll try to put some pics our today. Compare to 2 years ago my top speeds are down by 4 or 5 mph
But 2 years ago I had a way less efficient splitter and wing at 3deg.

To balance my actual splitter I need the wing at 7deg and I believe the diffuser Increased the drag too. But i will test with and without again soon to prove one way or the other.

But on the other hand the car after lots of adjustments (new suspensions. Different Aero. ) was really Planted. Maybe too planted so i might be able to reduce aero and drag to maximize speeds.

Excellent, i suppose you have a boat load of spring choices.. stiffest i got with pure stock aero is 500 front 300 rear (s197). Thanks for updating the build thread.
