i am running in my first Rennlist track day near Toronto on Thurs. Its a long day ie 30 mins track time per hour from 9-5. I have read lots of threads on tips etc. One question that still has me a bit uncertain. I have the Hankook v12's and usually run the recommend street tire pressures. I have read that I should keep them below 40 on the track. So should i just show up with my regular pressure and adjust accordingly or start lower ? I am a beginner so not sure the tire temps will make the slightest bit of difference

Just obsessing as i am a bit excited about the whole thing. Thanks for any advice!

You will have blast.
I would start at 33lbs cold. Bleed off pressure at the end of a run to 36f-38r.

If this helps, I run fast street tires on the track (Dunlop Direzza Star Spec), not R compounds, but pretty good.

On street tires, I shoot for 36/38 front rear HOT. Depending on the weather, that could mean 8-10 less PSI cold if you're really moving. I assume a 2 PSI drop between cool-down lap and measurement in the pits.

If temps are cool, and you're just getting started, you might try 36/38 less 4 PSI cold. Once you come off track, take a hot reading, and reduce pressure as necessary.

Have fun!

That's a lot of track time.

Please make sure yer brakes have been bled, eat enough and stay hydrated.

Have fun!!!

+964 on the hydration statement. Also, if you feel yourself having a really sloppy session, consider skipping one session. That's a lot of track time right out of the gate for a beginner, and I always found that when I was starting out, I would get really sloppy, and have the most issues/mistakes in the last session. I agree with matt on pressures, try that.

I'll be there, too. Have you been to Mosport, before?

I would suggest sun protection, something to sit on, and snacks that meet your normal dietary requirements. I find that it's really easy to feel off there if I'm not eating well. And don't overdo it on the coffee -- it's a long walk to the washroom!

Thanks all. It is a lot of driving and I will be cognizent of skipping a session if tired. Pontifex4, I have been to Mosport before but not on the big track. Look forward to meeting you and I will stay away from the coffee!

Full report when you're back, please!

take it easy and be aware of yourself...if you start making mistakes or getting sloppy get off track and skip a session. Drink lots of water, no soda or coffee...and have tons of fun!

Just reporting back after my day. It was perfect; sunny and warm. I ran 6-30 min sessions with the green group over the day and really enjoyed it (had to fill up halfway through). Had a great instructor for a couple of sessions which was very helpful.

I ran 32/24 cold which seemed to work well (i stayed on the track) although one guy ran 38/44 cold (i think he reduced it after we spoke). In the last couple of sessions I took it easier and watched the other drivers more (as I had plenty of time as they passed me!!) and work on my line etc.

I was quite surprised by the grip and the speed these cars can carry through the corners. It was pretty addictive as we picked up the pace and I will be back for other events!

Thanks again for the suggestions.
