Just to reiterate Croc’s spot-on comments.
Yes! Yes! Yes!
Enough cant be said about the importance each of these, especially corner weighting. I can tell you from personal experience that proper corner weighting can make a huge difference in your getting through a ‘corner’ quickly, and safely.
Proper tire pressures...ranks right up there with corner weighting.
I’m not saying to put a wing on your car, but adding this in because I do drive a Stalker. And I run with front and rear wings when on track. FWIW, with my current staggered wheel/tire setup, when running on slicks on a damp/slightly wet track (yes, with slicks), my car absolutely pushes through the turns. This not to say that I don’t get oversteer as well (Croc can verify ), only that the tendency is for understeer. Example; I did a two-day event at COTA in November. It rained the entire two days and the temperature never got above 50 (proper tire pressure comes back into play here, as well). During those two days, I had more predictability with my slicks and would simply drove (guided) the car through the corners using throttle (more throttle, more push....less throttle, less push).
in short, pay close attention to what Croc is saying...it’s gold.
