    Is a car faster without back seats AND no bulkhead or was Feb 2021 a coincidence?

    I think it was the event after this I bought my 10hz GPS thingy too.

    I definitely considered the data glitching to give me a 2:12 but elsewehre on youtube I have a 12 minute or so clip of me running consistent 2:12s much like the consistent 2:13s.

    2:11.045 with 1hz gps on the 2:12s day.heres an overlay of 2:13.1 with a wing amd re71r vs 2:12.079 on hankooks last year. the wing seems to add a little drag but faster than i was a month earlier without it net lap time.

    I think you put way too much faith in that gps being accurate...

    No difference in corner exit speeds. I don't think the difference was weight. I know the aero made my head buffer around without a back seat. I'm wondering if this somehow reduced the drag coefficient of the car

    Clarification, I've been in the zone since and still get 2:13s.I just looked over more data and noticed....The top speed was higher than day on the straightaway. My data shows the Re71R just a hair faster in several key corners a few weeks back, but on Feb 6 2021, the car just had top...

    Looking for Reviews of Michelin Slicks SM9+ specifically

    I may have a chance to get some 27/65R18 Michelin SM9+ tires. That narrow, it would seem that its likely a TCR car. Does anyone have info like....What "publically available" tire does it drive like? How do they wear? (sessions/days I can expect) Do they heat cycle or wear out first?

    On RS4 tires on a cool February day, after VIR has had little to no traffic in awhile, I ran a 2:12.078 at VIR. I was elated. The tires were brand new, a taller profile, and I was in the zone. 2 months later, I was back to 2:14s. The chief instructor of the group I ran with in February since...

    Anyone like damp sessions? I ended up on track with some RE71R for a light rain that had the track pretty greasy.

    How much time are curbs worth at VIR? Watch to see. I ran these 2 laps 5 minutes apart.
