r/CarTrackDays

NCM says for thier Intermediate 1 group, driver should have these qualifications/experience (see below). I've done a couple SCCA TNIA, been AX'ing for 25 years. Did some track days back in 2006-2010, then not again until 2024. TNIA is not listed on MSR, I don't have any "validated" exp other than being there (some photos). So, what do they really want to see other than my own opinion that I'm better than Novice? (Sent an email, waiting for reply.)

Int 1: Drivers at this level have visited different road courses, have 10 or less track days listed on MSR, and have received in-car coaching/on-track instruction. The driver has already satisfied solo qualification protocols. Driver is fluent in passing protocols.

I have a trackday planned in a couple weeks at Monza and I’m thinking about whether should I skip it cause it’s probably going to be like 35 degrees (C). It’s an open pitlane event so I can do very short stints go out cooldown the car and all that.

What are your thoughts and experiences with this kind of weather?

EDIT forgot to mention humidity in the morning when I arrive will be around 70% dropping around 50% as the day goes on

I've observed that when my AWD car is understeering badly if I apply throttle it'll rotate more. This makes sense on a loose surface like gravel or snow, but I've observed this on tarmac as well.

This goes counter to everything I've seen or read about traction. Everything I've seen or read says that applying throttle during understeer is exactly the wrong thing to do. It transfers weight off the front and puts the front tires even further outside their traction zones. Yet I keep observing this.

I can't be 100% sure at this point that the car's ESC system isn't doing something to cause this. It doesn't have any of the fancy torque vectoring differentials and I'm not noticing it doing anything, but it might be applying inside brake that I'm not noticing. Though still this seems unlikely as if it was it'd likely do it off throttle as well and it feels like the outside front is pulling not the inside dragging.

Maybe the way my AWD system works it's actually slowing the front tires relative to the rear. It's a RWD based clutch system, so applying power causes the clutch to grab. Because there's no center diff and the front tires turn a larger circle, it may actually be slowing the front and spinning the rear more. But again as I said before it feels like the outside front is pulling the nose of the car around.

Has anyone here noticed such a thing, there's quite a few here who track FWD cars. I figured maybe some FWD drivers might observe something similar.

while i understand the basics of brake in and don’t accelerate until you’re easing of your wheel one thing i don’t understand is what to do after braking and before applying throttle do i come off completely from the throttle or do i stay on it slightly for the car to not slow down as from what i understand if i let off throttle mid corner it will cause the weight to shift to the back and cause oversteer

Hi, I was looking at getting a Simpson hybrid S for the added layer of protection with my stock seatbelts. I'm not looking to implement the full HANS safety system as I want to keep some daily drivability with the car (981 cayman).

I saw someone mentioned REVX Carbon - Head and Neck Restraint as a cheaper alternative to the Simpson hybrid S.

I was wondering if anyone also uses this with street seatbelts? Is it easy to fit and comfortable in stock seats? Reading the product's description, I can't quite tell whether it is intended to work with 3-point stock seatbelts or more for harnesses.

Thank you!

I have a GoPro Hero 9 and an AiM Solo 2. Race Render is junk IMHO and Telemetry Overlay is a ripoff, so do any of you use free versions? Or are these really the only options?

Is pulling the fuse that controls the aero hydraulic pump and unplugging the actuator connectors sufficient? Should I have a shop fabricate pins or brackets? What’s the path here?

I know this isn't a big deal, but it's a goal I've been chasing for a year now, so today was a good day. I'm also happy I did 2 sub-2m laps, so it wasn't a fluke :)

Finally got to do this one after attending many races there. Stock car except for Falken RT660 245/40-18 on Enkei TS-10 18x8. This was my best lap, 1:33.85, on a wet track. Was hoping to go faster if it dried, but it only got wetter!

Lots of lift-off oversteer, so it was important to avoid trail braking. Brake in a straight line, then turn in. Stay off the curbs. Slow in, fast out. The diff was amazing on corner exits. Ran down this CTR and a GRC pretty easily.
