Race Tracking Your Supra - Information exchange

[Evolution]

Adding to last post. We got shut down in the morning thanks to thick fog. Also, I do not like waking up at 4am.

And lastly, poor s2k..... lots of cars off the track today.

Gt3rs not getting away video incoming.

Spoiler, he loses it twice.

*I* did 1'57" with a stock Supra. I could do a 1'56". You BETTER be sub 2s with all your stuffs.
Do I need to come out there and give you a hand? I promise you we will get you sub twos.
I WOULD go out there for some instruction, if you don't mind.
Plus, I can bring Sophia.
Your car will do a 1'53"-1'54".

i use to have a turbo ap1 s2k for almost 10 years,

in so many ways i fell like the supra is a modern s2k.

to see a broken s2k always hurts me.

Surprised you didn't let your race shop set up the garmin.

Duuuuuuuddddde….. Coulda, shoulda, woulda
I still put in my own gas, hahaha.

I tried searching this thread but with 155 pages its a lot to go through. I'm a total rookie on a track, other than a couple of autocross events in a Miata.

I'm ready to book my complimentary HPDE-Intro track day, but could use some sound advice from anyone who is experienced. In my head I'm one and done, but I know me... will likely want to do more.

I'd be going to Mid-Ohio racetrack. Available dates are in April, May, and August. Is there a temperature preference for this? Any advice on prepping the car... or myself? Thanks!

You definitely don’t need 155 pages here or an oil thread review. After a while you’re looking for something to pick at. Anything that might shave off that one hundredth of a second. Just go out and have fun!! Below is a nice little list from Chin Motorsport:

NASA is very similar. Flags are the same. As long as you’re willing to listen to your instructor & others, it’ll be a great experience. Worst problem would be someone that knows it all or blames others for their mediocre lap times. That’s rare & doubt that’s you, lol. The majority of the peeps out there are just like us. Love cars and actually driving them

and maybe don’t follow others this close (45 seconds in - tailpipe colonoscopy being preformed)

Went off at the end of riverside.... probably going 100. The dirt is soft so it caught and rolled. So don't do that today and good luck on the 1:55!

So how did 275's work out for U compared to 305?

They actually got up to temp! Because of that, I would say more grip than the 315s. Car also felt a little bit more alive since I dropped a few lbs per corner. They did get greasy towards the end of the sessions so I think 295s are going to be perfect.

I think a spring rate bump is in the near future. There was one turn that I would come into around 100 and you could hear the splitter scraping the ground.

Stretched tire will perform much better than pinched tires… contact patch size in this scenario is determined by tire pressure anyway so the wider tires probably aren’t even providing more grip

What Your take on 275 vs 295 Kyle? 400whp
18x9.5 wheel vs 18x10.5 ( Dunlop recommended sizes for Direzza Z03G, narrower/wider works too but they recommend as above to be best performing)

295 is not optimal on a 10.5. Like Kyle stated, it will be pinched, not stretched.

So U say Dunlop themselves are wrong recommending wheels size for their own tire? Coz its their idea + confirmed by biggest tire shop here in PL who sells tons of motorsport tires.
Im thinking between 265 vs 295 (so irl 279 vs 299)

You can see that from EVERY tire manufacture, just because it technically fits, doesn't mean it's optimal.

Sure, but those mid values are Dunlop recommended, confiremd with tire supplier.

Sounds like you have it figured out. Why ask the question?

Coz I wonder if 295 is faster and should move to it, but have no expeience with bigger tire so I ask ppl who had? I'm not asking for wheels size.
