Hi Lyall. I appreciate the "tweet." I upgraded Scott's with the help of Greg, replacing the 450 lb/in front springs with 500 ones for crisper turn in. With the repaving of Watkins
Glen, some 944's are running 800 lb/in front springs with added 300 lb/in coil over rear springs to the 31 mm hollow torsion tube.
I upgraded race car from SP1 to SP2 by replacing front lower control arm bushings with Race Edge spherical bearing bushings, going to double adjustable front dampers and double adjustable rear dampers.
it was discovered that on the tight 180 degree turn 1 at Lime Rock, the car had severe understeer and after adjusting the original setting on rear anti-roll roll bar from 50/50 to 75/25 hard, the car was neutral and my lap time was 2 sec faster over a 1.5 mile race track w/o pushing it.
What is your race car?
Happy New Year,
Tom

Fordahl really knows how to make Porsche race cars handle and races his own 944.
My car is a 85.5 (March 1985) and converted to a race car by Fordahl winter of 2007/08, same as my buddy Mark in the Gray car. Scott, Mark and I began racing in 2008 after years of doing PCA DE's and A/X.
I've had the Elephant Poly Bronze / Spherical bushings F/R and Tarett F/R sways on my car from day one. A few of us are moving to 2x adj JRZ's this winter. We're all still 450/31 but losing the t-bars and going full coil-over with similar high spring rates is on everyone radar.
I'm still 50/50 on my rear bar but can see how the extra 50lbs upfront required a small bar change in the rear. Get ready for brain damage and a notepad when you move to double adjustable shocks.
Couple more pictures. The donor car on Christmas morning 2007 then at speed at PIR.

Here's one I've been working to get to her first track day...38 years after she was born!
#14 of 16 factory DP cars, never raced, plucked out of Vasek Polak's warehouse a few years ago. Getting close...

Like the car photos.
When increasing front spring rates, I adjusted front ARB from 50/50 to 75/25 soft to compensate for 500 lb Springs.
The car was "neutral " at Watkins Glen, 9 of 11 turns are large radius. It was understeering prior to Apex to track out on tight radius corners, double apex keyhole and carousel at Mid-Ohio and 180 Big Bend at Lime Rock.
Maybe you can query Greg F if he initially sets up his customer cars for understeer (safety for a novice race driver).

were always at the sharp end of things running PCA A/X as well. Here's some in-car from Pacific Raceways if you've never seen it... This was with SOVREN, the vintage folks.

Fordahl's setup was dialed in for Pacific Raceways and Portland and we all ran Koni Yellows. For Portland we ran 1/4 turn off full stiff 1/2 turn off full stiff for Pacific. Greg wasn't trying to keep us safe and knew us all well. We had many years of PCA DE advanced run group experience in much faster cars. 2/3rds of us were always at the sharp end of things running PCA A/X as well.

I appreciate the clarification..I enjoyed the in-car video of you racing and dicing with the Super 7 and #38.. Good clean racing and lots of fun. I believe we would have benefits sharing what we are doing on car maintenance and racing experiences, Check my PM
