RT660 is not as fast as the CR-1s by quite a bit, even on this cooler day. The CR-1s just had grip everywhere, no matter how quickly you loaded the tire. I felt like the RT660s got overwhelmed easily. Still gave you decent grip but not consistently. Hard to explain. 

My new 2.75" front splitter height produces way more downforce than the wing. Low speed the car understeers a bit. High speed the front end is a laser beam, and while the rear is still stable, it just doesn't have the grip to keep up. I plan on eventually ditching the APR and switching to the nine lives with the dual element upgrade to keep up with the front aero. Will definitely be making an active aero system for that second element to minimize the massive drag it'll induce.

12kg front isn't really enough to handle the 12.25" ride height and splitter position. It's okay on this track but if i want to really go curb jumping or launching over bypass i'm going to need more platform, preferably with a more race-oriented damper. I'm really not interested in dumping more money into the car though, so i think i'm just going to dial out the rake, give the car enough ride height to deal with the curbs i like to smash and try to have fun without chasing setup so much. 

Oh and i filmed a tutorial on how to make the splitter so just bug me enough and i'll get around to editing it lol
