Interesting that you thought the Supercar had better grip than the RS4. Quite a few 1LE guys are using the RS4 in a square 305 setup and reporting quicker times. I for one will be sticking with the Supercars because I like the way they feel, both on track and in autocross.
I have not run the Supercar 3Rs on my car, only the Supercar 3s. However, I would imagine you would still be aiming for the same hot pressure of 35, starting around 28. If I remember correctly from my PP2 this was the same hot pressure as you would aim for on the Cup2s.
I really wish this thread had been around before I bought my 2018 PP2, would have stopped me dead in my tracks.
I guess the fact that my Coyote gnawed itself to bits early on was really a blessing in disguise.
Before you go this route and spend time and money, you should check with the organizers. I tried to go a similar route with the recaros in my 1LE: that is a custom anchor setup so that I could sit on the anti-subs. For NASA it was a no-go.
Ahhh my bad. They are also available in 19" sizes now too. Here is the link for the 19s:
Just to throw it out there, but you may also want to consider the OEM Camaro SS1LE tires, the Goodyear Eagle F1 Supercar 3. They are now made in the 305/30/19 sizes and hold up really well on track, even with cars as heavy as ours. Pace might be slightly slower than the RS4s. Here is the...
Should have been finishing up my 2nd or 3rd session at VIR today with NASA. In two weeks I won't be going to Dominion Raceway with SCCA either. Just got done setting up my G920 for some iRacing and Forza
I use TrackAddict with a GoPro Hero 7 and a PLX Devices Kiwi 3 for data recording. I really like the TrackAddict because it works well with RaceRender and the data from the Kiwi 3 seems spot on. Here is a video of my last outing at Dominion Raceway using this combination:
Had the same issue with my old Focus ST with Recaros. I ended up using a pair of Whiteline KLL122 Alloy Sway bar clamps (22mm size) to keep the seat from shifting side to side. There is a bar that runs perpendicular to the seat in the Focus Recaros. Might be the same setup with the Mustang...
First off, good on ya for getting to the track. It's the best way to enjoy the car at speed in a safe environment. Here are some answers to your questions:
1) When starting, do they space the cars out a bit, or do they just let a class go at a time?
NASA and SCCA, and probably most...
