I'm slightly less than 5'9" so in the same boat as you. Guess HANS wouldn't be ideal for me either.

Interesting. I've met many Boxster owners using HANS on the track and have not personally heard them complain about using the stock roll bar. However, from your description it sounds like the protection level offered would not be ideal in the event of a crash. I suspect it'll still work; just not as well as intended and designed for. Thanks for the info.

Looking good, Joe! I enjoyed running with you and Ben during the early sessions. I may have some video.

Next time indeed. Send me some links when you get the videos up. Hopefully I didn't hold you up too much! Lots of great drivers out there that day.

Ortho,

Are you using the Smarty Cam HD for your camera and data overlay?

The microphone works really well.

Peter,

While I'm using the AiM solo DL for datalogging, I am not using the smartycamHD for data overlay. A few of my friends do, and I've found that the video quality isn't nearly as good as gopro, and the audio is horrific:




My setup involves gopro cameras linked via wifi remote, an external mic placed behind the rear license plate, AiM Solo DL, and trackvision software to overlay the data.

Hey, Joe. Not a lot of footage. . . We were both still warming up the tires here so I didn't bother with loading the data too.https://vimeo.com/95239044

Thanks for the link! I remember this session. I have to admit, me and my friend riding shotgun with me at the time were wondering why you pointed me by a few laps later. You were clearly much faster than me. I think I pulled off right afterwards because I had a scheduled C7 drive I didn't want to miss

Did you drive the C7 too? What did you think?

Hmmm. Must have been the 59 car. Only the radicals and the big winged 914 passed me. I wasn't impressed by the vette. Steering feel was lifeless and that auto rev match was silly. Definitely not for me.

Whoops! I guess that means there were 2 dark colored RSs much faster than me that day!

I couldn't tell that the auto rev match was working. Agree on the steering. Again, glad to hear that my impressions are being echoed by others. I sometimes wonder if I really know what I'm talking about or not. LOL.

Yes. The 59 car is a 997 GT3 with some RS parts (e.g., wing).

And. . . From what I can tell, you know more than most here, including me. Carry on

Joe

good observation and looks like corvette done nothing to the C7 compare to C6 to correct it's inherent instability coming off T9. These corvette have mushmellow engine and tranny mounts designed to offer plush ride. What happen when you accerating coming off T9 the whole drivetrain slam to one side and cause enough weight transfer to destabilize the car. When I drove my Z06 in stock form coming off T9 I almost lost the car! Once I change to solid engine mounts and add rear wing the car is as stable can be through off camber T5 bypass and T9.

That center console issue is retarded - you need to have it removed or modify if you get a C7. Not allowing you to rev pass 5000 RPM .... that's BS! I rev my Z06 pass 6500 RPM first time at the track after logging couple hundred street miles. Auto blip switch position is not good. Power? really not much to speak of unless you have over 500 Hp/Tq and can be easily gain from intake, software and exhaust

I would be as nice as you with my feedback if they only allow me doing 2:20+ parade lap. I would have said "man, after driving this pos I decided to get a cayman"

stock black rubber tranny mounts vs aftermarket solid mounts

Thanks, mike. Very interesting to have you confirm that the instability of the car is an issue even with prior generations of the corvette.
