I also have the wing higher with the BBI wing uprights so I'm very curious how much more speed I'll get in the fast sweeping turns. I didn't add any canards for the front, I'll see how the car feels and if I'm getting more understeer than normal I'll install some canards on the front.

Post production is a total PITA the first few times you do it. I have templates now, and I've done it so many times that it takes little time and effort to make them now. There is a steep learning curve though.

I took a quick screenshot of the time difference I noticed. There's a couple seconds between the phone on the dash and the timer on the left of the YouTube (post production) frame, not the Solo. Just curious. Awesome driving as usual.

I'm sorry, this screenshot contains a vehicle with an automatic transmission.

Unacceptable.

That is because the start/stop marker that the track app uses is different than what is set on the solo, which is what the video timer is based off of.

Lol, but it is an awesome transmission. Don't knock it until you've driven it! Given the option, I choose PDK-S for a track car.

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.

Attachment 1146744

My car has the stock engine and exhaust. The tires are well worn Hoosier R7's. The suspension is all monoball.
Impressive 24 Chromium! And Congratulations for have the BEST TRACK TIME at Thunderhill - sub 2 minutes is an accomplishment!

Thanks! I'm curious as to who holds the record for the most number of track records on your list. I'll have to manually search it when I have free time.

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!
I enjoyed your video aryork - seems Guards Red GT4s are just a wee bit faster than other colors! On the board!

EDIT: Oops - I see that trebien edged you back one spot Mike - but still on the board!

Nice driving Mike. Appeared whitey GT4 had stickier tires, but your shortened the course in several places and kept close - very nice! Moved up 1 spot on the board.

Sweet! Looks like I hold that record with six tracks. And in the next couple of months I'll be adding a few more!

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!
You kept electron mike behind you, nice driving! Your turn ins were wicked quick. Impressive lap time, moved up a spot on the board!

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
Oh so very close to breaking 2 minutes. But, not bad considering you were driving a yellow car Always a pleasure watching your videos! THE fastest hands in a GT4!!!

Couple of "stock cars", race GT3s and a GT3 RS in my run group. Very fun. I'll have to find some videos of the stock cars passing me -- my ears were ringing.

Ended up with a fast lap of 2:09.74 on the full course.

At NJMP I play with a lot of 997 and 991 GT3s and never really felt under powered. However, following this 991 GT3 RS really makes me want a boost feature on the straights.

You guys running 2:03s have some serious speed. I believe I have about 2 secs left but beyond that, my pucker factor would be way too high.

(BTW - Matt - my NJMP Thunderbolt time of 1:29.86 (see post #550) still need to be added.)
Got you updated now John - both with at VIR and NJMP. Still the fastest there is at NJMP!!!

Ha, sounds like the gauntlet has been thrown down!

Nordschleife - 8:23.13 (stock car off the factory floor, first day at the 'Ring)
MSR Houston CCW - 1.46.01 (100% stock car, 20" OEM wheels with RE71R, first day at MSRH)
Sebring - 2:25.87 (100% stock car, 20" OEM wheels with RE71R, first day at Sebring before tranny blew)










And Lar, really... we need to talk about this:

How many laps do you have at CotA? That was my very first day. On very worn tires.
