Excited to run Laguna Seca once the traffic is gone from car week... Heading down on labor day with speedSF! Trying to get into the low 1:40 range. Mainly need to be go flatter on turn 1 (#pucker) and figure out my line for 2... Suggestions?
Speaking of aero things can you shed some light on the front splitter you have? Tangible gains? Any stability problems without rear downforce at speed?
Honestly I don't have any good data as I installed it a while back and just use Harrys with an external GPS. Aim solo is my next toy but I would say that after removing all seats the car has a tad less rear grip, I've adjusted by reducing rear tire pressure 1-2psi. This may also be a function of the front splitter?

The splitter only protrudes 3 inches as I was trying to follow (somewhat) the enthusiast class rules for Redline Time Attack. A rear wing would be great as this platforms short wheelbase is pretty twitchy
