That was wild to see friends pictures of that sunday morning. I did see a mustang in one of the pics sitting almost halfway up on its wheels in water. Hopefully the water stayed outside but Im thinking that thing might be a flood damaged car now.

There at least one CSM car that got flood damaged, Marty Montagno's convertible had water pretty far up but when I talked to him in the trailer, car ran that afternoon so might be ok.

When I got there Saturday night at which point rain has been almost gone, river had about 3-4 more feet to go and I thought we were good (which is why I have moved only the car and not the trailer with all my shit). 6am Sunday morning river was flowing through the paddock.

It's not the first time it happened. Event still ran (2 runs, no sweep / corner sheets or impound) but course was changed and still had a mini-river flowing through for which you had to slow down, wait for the car to hydroplane going through it and then try to turn without hitting cone wall.

Overall pretty wild event (given temps during the Pro), glad to be home relatively unscathed.

Following along with my weight loss journey... With the added SC and wing, some of the weight reduction done basically offset that.

Crows landing we were 3840 (without driver) at 1/4 tank.

• +40 : SC
• +?? : Wing setup
• +16 : Vitours are 4lbs ea more than A052
• -9 : Billet uprights
• -17 : Driver Seat
• -35 : Tiny battery
• -9.5 : Front bumper bar
• -9.5 : Factory Sub box
• -~10 : Rear junk (cover, foam thing, etc.)

Right now working on a few more things. Some are only weight reduction, some are incidental weight loss.

• -33 : Rear seats and belts
• -22 : Passenger seat, hard mounted, no slider.
• -6 : Steel Sub mounting bracket
• -12.5 : Rear bumper bar
• -3 : BMR camber arms
• -2 : SPC Toe arms (modded to fit Ford Perf sealed spherical)
• -3 : Floor mats
• -8.3 : Removed rear sway bar (going back to a no-rear-bar setup)
• -3 : Changing Steeda 35mm to eibach 35mm
• -4 : RE71rz's are 1lb lighter than Vitours (yes, ditching the X1... Ill either sell them or burn up at locals)

Im still a heavyweight, but boosted I'll be at 3750. 100lbs lighter than last year with only coilovers and wheels for mods.

My list of other changes would be enough to get me in the 35xx range but things start getting expensive and/or very custom.

FWIW, Jeff Wong's ZLE Camaro is 4050 without driver and running 305s. Dont know what Dave's car is down to but guessing its quite light in comparison. Would guess 33xx.

Wong is going to have to be pretty good to beat another camaro which weighs 700 lbs less.

Maybe it was 3950, It was heavier than I thought though. ZLE is a pretty heavy car, though not as bad as a GT500.

I remember looking over Otis' camaro years ago and there really wasnt a ton of weight that was easy to remove like the Mustang. Our rental car roots really help with all those steel bits waiting to be replaced.

Until you realize how flexy the S550 chassis is compared to the GM Alpha platform.

 

[Dallas J]

No argument that the Alpha chassis is superior, GM crushed it with that platform. Just sucks its like driving a submarine. Ford also had to make the rear suspension super weird, assumingly for drag racers.

But, the mustang still has a lot of potential.. hence why were all here.

 

[Dallas J]

Went down a bit of a rabbit hole trying to find torsional stiffness numbers and some things stick out as surprising.

S550 - North of 20k nm/deg (cant find a specific number)
Gen6 Camaro - 39k nm/deg

Thats a big numerical difference, but theres diminishing returns with this so was curious what other cars numbers are available

Evo9 - 24k nm/deg
RX7 - 15k nm/deg
RX8 - 30k nm/deg (this was a bit shocking)
997 Carrera - 33k
Carrera GT - 26k
Ford GT - 27k
Bugatti Veyron - 60k
C7 Corvett - 14.5k (T-tops and Targas are dumb)
E92 M3 - 33k
F80 M3 - 40k
G80 M3 - 46k
Tesla Model 3 - 20k to 40k depending on source

So seems like 20k is good, 30k is great, 40k is top tier, more is more. ;)
