I finally got my laptop and MoTeC data from our CotA trip for the PCA club race in March. I managed a PB of 2:30.4 on my first (and only good weather) day.

And here is a PB from my home track, Thunderhill, at this past weekend's club race. This is the 3 mile Cyclone course. It was my first time in this car at TH. I did a 1:59.9. Plenty more to be found. I'm still trying to grapple with moving from a rear engine Cup car to a mid-engine street car with 50 or so less horsepower and less aero.

My car has the stock engine and exhaust. The tires are well worn Hoosier R7's. The suspension is all monoball.

VIR, 2:12:05 (video says 2:11:9), 3/19/2017. Stock wheels, Cup 2s. Stock suspension, max camber (-1.7 F / -1.5 R). Max stock aero (wing & remove spoilers). Fabspeed sport headers. Using Porsche Track Precision App (with Dual precision GPS):



I didn't realize my fastest lap included two passes. The first pass caused me to screw up turns 3 and 4 because there's no way that was the fast line through there!

Nice lap! In case you want more rear downforce, since you already have the wing risers, I was thinking there's enough room for an extension on the rear ducktail to be effective. RSS has one for $700, which is silly money for that part, but I'm sure something else could be made to achieve the same function.

Great weather this past weekend at COTA! Same setup with bald RE71Rs and a lift to let the Wolf by: 2:31.9. Thumbs up to the driver of the white GT4 if you are on Rennlist!

Maybe me - with the fancy blue painter's tape numbers?

(edit - watched the video, I see the painter's tape... guilty as charged!)

COTA - 2:31.50 - 100% stock car, stock brakes, stock alignment with stock 20" wheels and RE71R

I tell you what, once you get the lumbar dialed in for the 18 way sofa sports seats... it's worth close to a second per lap!

I was at Thunderhill this weekend running my GT3. Got a new PB in the GT3 there by 0.2 seconds, so I was itching to try another PB in the GT4. Unfortunately, I didn't bring my car. So, I swapped cars with doborder instead and beat my prior best time..... by a measly 0.04 seconds. LOL!

Doborder's car is pretty much the identical setup with mine except he doesn't have the DSC unit. RE71R tires on their last day. You can hear me swear to myself after screwing up T11 and then the disappointment after crossing the line. LOL

2:00.14 with me driving doborder's car

Nice job, Lar! It was fun getting sandwiched by you and Mooty on Friday. You should do a write up on your car. It's a pretty amazing and unique setup that people will 'wow' over.

Which begs the question, were you able to discern any difference without the DSC?

No. I think the springs negate the the DSC benefits.

Don't let Orthojoe drive your car....He will make you want to go out and do more sessions because he can cut two seconds off your best time... in your car ....

Thanks, it was a great weekend! I love running with Chin, but I can't make it that weekend. A bunch of folks are going, so you guys should have a blast, I'm jealous!

Nice time, especially with essentially a stock GT4! I need the 18 way lumbar secret, I'm flying around all over the place and want a real seat and harness.

Thank you. I had the seat re-upholstered with velcro, and have a matching velcro suit.
