I know it's probably not the right setup, but the nitrous and 4.2 liter cheater motor I run helps me overcome the lack of grip.
Yep, thats the setup I run. I am not a suspension guru so I really don't know why is works.
When I bought the car from Mike Levitas at TPC this is how he recommended that I run the car as an amateur. He indicated that I would be leaving a bit on the table but that it was a more conservative setup. This is the setup I have run in every race.
Perhaps I will try a new setup during Friday at R Atlanta.

I raced a cup car setup like that, and it really didn't work that well. I started dialing out the understeer, but was so new to the car, and so unfamiliar with the way it should handle that I didn't go very far with the adjustments. If/when I get a chance to race another one, I know exactly what I want it to do.

Well that's really interesting Chris. I'm not an expert by any means, but that combination of full stiff/front, full soft/rear, should give you massive understeer and all but eliminate any chance of snap-oversteer. Your cup should turn in like the QE2 yet it obviously doesn't based on your very successful past year. It makes me want to soften my full-stiff rear bar and see what happens. I remember you posting that you experienced snap-oversteer at Sebring with the Michelin Blues and stating that had never occured before. I wonder what would happen if you stiffened the rear and soften the front a notch. Hell you might be running with Leh....

Now, I don't know enough about the front strut on the Porsche, or the geometry changes made to the suspension on the Cup cars, to know if this might be a similar situation, but it seems like a possible explanation. Has anyone else seen this trend in Porsche's?

Bryan, wouldn't this all predicate very heavy spring rates? I know on my M3, I do not have enough spring rate for this set up to work, but for the guys running 900 pound + springs, it seems to work great.

OK, follow-up.
I ran two weekends back-to-back at Thunderhill, PRC the first and a SCCA Double National the second.
In PRC I finished 8th of 10 Cup cars in the first race and 7th of 7 in the second race (after a little incident). Fast lap for the weekend was a 1:58.6.
On Thursday of the following week we worked all day on the set-up and found a 'better' set of used tires for the weekend (Why can't anyone deliver Cup tires???).
For the SCCA weekend we had 6 cars in the GT2 class - 3 Cup cars and 3 other cars. Saturdays race ended in a second place finish and Sundays race was my first ever racing win! Fast lap was a 1:56.6 which is within 1/2 a second of the fastest Cup cars from the PRC weekend.
Whooohaaaa - I'm now the North Pacific division SCCA GT2 points leader! Maybe I should plan for the Runoffs where Analog Mike took 6th place in 2005 with my car. Still lots to learn but it sounds like fun.
I love driving this car!

Awesome!!
Glad you are getting the hang of it! Sorry the setup was off, it was professionally aligned with no track time on the new alignment after the bodywork was completed.
I just got back from several days in the FL Keys, will answer your email asap.
Have fun and hope the car gets it's 2nd SCCA divisional championship this year!
