Yes. it surprised me. The Hankooks have very stiff sidewalls and the suspension I had on the car was perfectly matched for them. I suspect it would also work really well with R7's. The stiffness of the car tends to overwhelm the NT01's, especially in the rear, even when the dampers were softened dramatically.

I think it's more that a mismatch of spring rate and sidewall can lead to premature overheating of the tire on track .

Yes...so it is not that I'm hard on tires in the M3...it is that my NT01s were mismatched to my spring rate. ![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
I've been trying to kill the NT01s on the Miata and can't do it to save my life. Course, it would help if I could keep the car on track for a full day w/o mechanical problems....
Hoosier scrubs seem to be hit or miss. Set before NT01s were more slippery than the 2011 rain tires. Tried out a "new" set for a session and they were slightly better than the NT01s.
I've been told this is all in my imagination, though.![Roll Eyes (Sarcastic)](https://rennlist.com/forums/images/smilies/rolleyes.gif)

page 111 .. what a mommoth repository of all things racing!
I haven't posted for a while but always interested in the views expressed on these subjects so thanks.
Small question though ... seems one of the marshalls today was wearing a camera on his head - useful!
So is this a fast approach to the corner?

Yes but I should get some point for style ![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
I brake latest of all on that corner after the longer back straight ... so no denying the fast (or maybe too fast) in ... but it works for my quali lap times and passing into that corner
but it does make catching a slip stream and having enough space on the next straight (which follows that corner) to pass into the next corner harder .... swings and roundabouts I think
also it may be heating the tires up too much i.e. the late braking?

4 laps from TWS with Chin. I am in my stock 996 GT3 on AD08R tires. 295-35-18 in rear and 235-45-18 up front.
4 Videos from iPhone and one from GoPro in the car
I'm asking for general comentry; line, acceleration etc.

Just a couple of things, Tor:
-you are pinching the exit of 2...don't be in such a hurry to being the car back left for 3
-apex 3...it's important
-start your turn in for 6 a bit sooner but with more gentle steering input...round it off a bit more and use the natural camber there
-go a bit deeper after the first apex in 10, in order to make the second apex, which sets you up for a better & faster launch into and out of 11
-go up to 4th gear before 12 and use more throttle position in 12
-go up to 5th gear on the main straight
