I drive a base model 2003 Silver Z, the car is bone stock except Nismo LSD(only good for drifting!haha) My best lap at thunderhill April 2, 2006 was 2:11 in semi wet condition with HAnkook RS2 street tires. Btw, it was a tight battle jason! We should do that more often!

I was at the NCRC yesterday and luckily the sun was out for 70% of the day. Portions of the track were still a little damp (edges of the track) but the racing line was dry...during the time trail I clocked a 2:14s (running with the cyclone). The RA-1's hold so much more than the OE tires! I carried enough speed through turns that I was hitting 105MPH before turn 9 & 10, and 120 before turn 1...I still have so much room to improve on turn 1 - it's just so scary going into that turn [usually by the apex, I wish I had been going faster]

Dave, good call on the raybesto pads - my biggest problem was that I would tend to use the same braking points from last time, so I would finish breaking well before my turn in points...hopefully I can pick up a few seconds just in better breaking. (I also realized why I melted my brakes so badly last time; when I would start breaking before a turn, I would be near 100%, but as my speed dropped and I realized that I still had some extra breaking zone, I would drop by breaking to 50% [or around there] until my turn in point...this time I was trying to go 100% until my speed was correct for the turn, then hold my speed until with the throttle until the turn-in point)

I'm thinking of going back to T-hill Friday, March 5th w/ NCRC...speed is adicting

Peter,

Great driving out there! A few months ago, you and I were clocking about the same lap times. This time, I couldn't even come close to keeping up! The weather did turn out WAY NICER than I expected, and I was very happy with the day.

In the end, I still ended up with 2:19 on the same street tires. I've hit a "wall" on my lap times, and will seek more instruction on where I can improve my driving. I did notice my ABS would trigger more than usual and had to brake sooner. My increased camber (-2.75 degrees) up front effected my braking a bit more than I expected, but I had much better grip and balance in turns.

I think where I can make up the most time now is T9 as I'm not slipping and sliding there yet. I feel like I really pushed T1 and T8 enough where gaining more time there wouldn't be worth it. The car just bounces around on T1 & T8 with a short screach and rotation every time the suspension unloaded.

Did you check out the lap times on the stock C6 Z06? I timed one of his laps at 2:07. Holy cripes!

was that the yellow C6? During the time trials, my last lap I was going into turn 10 with no one in my mirrors, between 13 &14 (back straight) I saw him gaining very quickly - it was scary how much quicker he was!

Yes, that was him. From what I hear, that was his first time out at Thill with that car. What a monster! Looks like Chevrolet really got this one right. The spec sheet looks as good as the car looks in person; simply amazing. I can't believe how something like that can get into almost anyone's hands nowadays. I'm not even comfortable tossing the Z around yet, so I can't even conceive the thought of learing how to toss one of those monsters around the track. I'm thinking that he hits ~145mph on the front straight. I know the GT3 Cup hits 149mph from a motec printout.

Did you see the Silver Porsche GT2? That car was shod with 285/315 MPSC tires on Fikse wheels, Moton Clubsports, and ceramic-composite rotor/brake package. Talk about throwing money at a car! I think his tires still looked brand new by the end of the day though

haha..Charles!! We did have a good run!
Cant believe one of my laps i got 2:12... Thanks for the pressure!!

Well, I just returned from a thunderhill track day with the Shelby Club. I decided to scrap my hot lap timer, and do the timing myself with the in-dash stopwatch. And, you wouldn't believe it....but I did 2:04 on street tires and stock suspension!!!

I'm never going to use that hot lap timer again since it's inaccurate as hell. All that time, I was breaking records, and I didn't even know it...

iTrader: (24)

2:04?!?!?!? Wow! Great lap time Don! Were you running the cyclone? Do you think you were running those lap times when we were at NCRC on April 16th?

-Peter

iTrader: (3)

2:04 is hella FAST! I did 2:10-11 in semi wet and I thought i did quite well. If there is a chance, you should definitely show me how to drive, I wanna learn from you!

Bringing this thread back from the dead...

I just did thunderhill on Friday the 20th and was able to hit 2:12's on the stock bridgestones RE040's. One of the rears chunked a bit but besides that they held fine.

I can't wait to throw on some sticky tires and good brake pads. I would say low 11's or high 10's are doable with these tires but good brakes.

I can attest to mistoco's times. He was very quick! We did Thill with the bypass. Good driving out there, and great meeting you.

I ran 2:12 over the top at T5 but I have V710's. I am just starting to push the car. I am the limiting factor right now. This was during a race with Checkered Flag Racing Association. It was a beautiful day in the mid 80's and only 20 cars per run group. The fast gus were running 2:06's in a s2000 with a wing and no engine mods. This guy is an experienced racer.

Heh, heh... 1:58s in my old 240Z with Lampe driving, 2:02s with me driving. Bobcat beat those times time in stock engined S2K when he laid down a bunch of 1:57s. Thunderhill is more about the driver then the car.

Here are the official track records at thunderhill. They look to be a little outdated though. I know the T2 record has been recently broken.
I find it hard to believe a stock engine s2k will break the 2 min mark, even with slicks regardless of the driver.

nice times mistico!

too bad I moved to Seattle...T-hill was a lot of fun.
