Re: Driving in the Rain

Paul, The miata has an incredible amount of roll stiffness - I'm guessing pound for pound, it's significantly stiffer in roll than your GT3. So, as David pointed out, you *really* need to disconnect at least your rear swaybar and preferably both swaybars for a "full rain" setup. Also, if you're runn...

Re: Congrats Laura and Dean: Lemon win!!!

Thanks, Trista! Coming down to a wheel to wheel battle after 14 hours of racing was pretty cool, especially since we ended up in the front at the checker :) It was great to see you taking that step into racing, and I'm glad you had fun. The path from Autocross to DE/TT to racing is a great way to go...

Re: 2009 Proposal: Revert Classification System

Strangely enough, there's one thing front wheel drive cars and 911's have in common. If you start to lose the back end in a high speed turn, YOU CAN'T LIFT!!!!! This is a textbook example. :) Happy Holidays! Dean BTW - The driver in this video was totally fine and the car was rebuilt and raced in th...

Re: GGR Members win the 25hours of Thunderhill AGAIN!

Nice pics, Trek! It was great to see you out there at the 25. Thanks for coming by to say hello and for snapping some great photos of our team, too. I should have acknowledged you along with the other GGR attendees in my first post, but I always think of you in the context of Trackmasters, etc., not...

Re: GGR Members win the 25hours of Thunderhill AGAIN!

I'll make sure Laura see's the congratulations, guys. She doesn't patrol the forums like I do :) I'm very excited for Laura and Juan and the 3 other drivers in that car. They did a fantastic job and deserve the win. As for my own experience... while I'm disappointed with our result, it was almost wo...

I'm very tempted to take up the fight and argue for reverting to the old system, just for my own amusement.

Re: Cutting Springs

Anyone willing to lie and cheat to this extent is probably also pretty creative. I think he'd find other ways to cheat more effectively with other modifications that are likely to actually make an appreciable performance difference. :) And to clarify an earlier point, cutting a spring that sits in-b...

TT#4 - An Outstanding Event!

I'd like to thank and congratulate Andrew, Gary, Dan, Ken, Paulette, Jay and the many others behind the scenes responsible for a great event this past weekend at Thunderhill. From my perspective, everything ran pretty much like clockwork. We stuck to the schedule, there were very few offs/spins/mech...

Re: TH: Faster or Slower after repaving?

Early reports say that the new surface itself it absolutely beautiful, but they have installed some steep (and high) apex curbs at T3, T6, T8 (!) and T10 that no one seems to be a fan of. There's already talk of them "shaving" down these berms. The apex of T14 is a work of art. They got rid of that ...

Re: San Mateo Mechanic

I've had very good experiences with Carrera Motors on Claremont in San Mateo. Adam and Bogey are honest, fair and very talented at working on Porsches.

Good luck.

Re: experience with GPS based lap timer system

Chris,

That's very cool, and a fraction of the price of an all-in-one data acquisition system.

Looks like you had a couple nasty 4-wheels-off incidents between turns 3 and 4, though! :)

Cheers,

Anyone care to do the math of what the spread is within a class? Most are 50 points, right, so for a 60 second course, what's the difference between the top and bottom of the class as a PAX result if it were based on actual points? Just wondering...

Oh, one other thing that I wanted to comment on. Grant - the fact that you feel you could jump in a Cayman S and do really well in PAX might be more a factor of the Cayman S being in the wrong class than the PAX index for the Cayman's class being wrong. I know there was a LOT of discussion about tha...

OK, now I do remember at least having the discussion. We considered whether PAX should be based on the EXACT number of points declared for a car or based on the top or bottom number of points in the class. The *right* way to do it would be to base it on the number of points declared for the car, but...

John,

That is GREAT STUFF. Thanks so much for taking the time to post it. As you point out, this should be a good indication that Porsche trusts its safety systems in the scenarios that it mentions over and over - on the track.

Bob, I don't know for sure if the TT class at NASA is run exclusively at their race weekends... They do have HPDE-only weekends, but I haven't been to one of them in a long time. It's possible that race insurance covers it (and DE insurance doesn't). But if so, that muddies the waters even more, sin...

Neil, I don't mean to be inflammatory, but your logic just doesn't make sense to me. You seem to be extremely safety concious, which I ABSOLUTELY agree with. But you seem to have drawn a line in the sand implying that in DE cars aren't in danger yet in a TT they are in GRAVE DANGER and likely to bur...

NASA has also been running a very successful time trial series for 4 years now. Theirs includes OPEN PASSING in a 20 minute session with transponders on all cars. Trophies are awarded per class per event and drivers accumulate points for year end awards. The preparation is the same as HPDE - no harn...
