Weigh in time

[Black Boss]

Thought Cross weight looked extreme, checked and floor was not level. Re weighed with scales leveled and a few more weight reductions (Driver and Passenger Air Bags, Driver seat slider, Aluminum Seat mount, Enkei Track Wheels instead of the Forgestar Street wheels) and got this with 3/4 tank of gas, no driver:

927 953
863 801

Left 50.4% 1790
Rear 46.9% 1664
Cross 51.2% 1816

Total 3543

Cross Balanced to 50% with Driver and now need to work on Driver weight reduction :

Is that with passenger seat in and track wheels/tires? Would be curious what F/R split was with full tank.

Yes Passenger seat in, Track Wheels and Tires. With me in drivers seat Front/Rear improves to 47.7%. I'm guessing it would be close to 48% with a full tank of gas. Plan to check that when I fit the DSS Driveshaft.........

Well that's better I was afraid I wasn't going to see the F/R benefit from the battery relo. I plan to get mine on the scales in the next week before TT so I can decide what class to run this year.

Total weight savings so far is 133 lbs with passenger seat and 179 without it.

With a curb weight of 3630, I'm at 3451 to 3497 with or without the pass seat.

Enkei PF01 wheels/Continental slicks:
Front 56.2 stock vs 43.6 - 13 lbs each x 2 = -26 lbs
Rear 58.4 stock vs 46.6 - 12 lbs each x 2 = -24 lbs
DBA 5000 front rotors 25 stock vs 210 - 4lbs each x 2 = -8 lbs
Corsa Extreme axle backs (pair) 54 lbs stock vs 24 lbs = -30 lbs
Kooks Off-Road H-pipe 32 lbs stock vs 17 lbs = -15 lbs
Side pipe delete 5.5 lbs each = -11 lbs
Kooks LT headers vs stock manifolds = + 3lbs
Roll bar, mounts & harness bar +69 lbs.
Rear seat delete kit +12 lbs.
Remove rear seats and belts and factory mounts -54 lbs
Swap to the Tiger Hood -17 lbs
Remove washer bottle incl fluid -8 lbs
Remove flat repair kit -5 lbs
Sparco race seat 35lbs versus stock seat 46lbs = -11 lbs
302S tow hooks +2 lbs
FRPP air-to-oil cooler +8 lbs
1-pc DSS aluminum driveshaft vs stock -21 lbs
DS saftey loop +10 lbs
Trunk liner -7 lbs
Passenger seat -46 lbs (track only)

I need to get mine on some corners scales to see how it looks. I'm not sure pulling the passenger seat necessarily helps due to potentially overweighting the driver side. Since I only weigh 175 I'm still probably be about as balanced as a lot of guys at 220.

WTF!! Rear seats and belts are 54 lbs?
I had no idea that would weigh so much. That is crazy. Time to do some seat removal

Corner weighed last night to see how the battery relocation helped F/R and to figure out what weight I'm going to run for TT this year. I moved the F/R from 54.4/45.6 to 53.1/46.9 which is even better than the 1.0% advertised by pufferfish The weights below are with a FULL tank of gas and with and without the passenger seat installed. Leaving the pass seat in place improves L/R and cross weight distribution. I need to run at a minimum weight of 3715 lbs. to stay in TT3 so can just play with fuel levels to get closer to that. Should be able to run as low as 1/4 tank it would appear.

With driver, with pass seat, full gas LF RF 1065 952 Total 3800 LR RR 898 885 Front 53.1% LF/RR 51.3% Rear 46.9% RF/LR 48.7% Left 51.7% Right 48.3% With driver, no pass seat, full gas LF RF 1062 936 Total 3751 LR RR 888 865 Front 53.3% LF/RR 51.4% Rear 46.7% RF/LR 48.6% Left 52.0% Right 48.0%

That's a lot of sound deadener Drew, wish I could get there but not ready to go the distance like you at this point. What is your front to rear ratio?

I think the sound deadener was only about 15 lbs, I weighed it in a bucket!


Front 55.9
Rear 44.1
Cross 49.0

 

[Black Boss]

Weighed with A/C out, DSS in and race passenger seat:

No driver:

Total: 3497

917 938
851 791

Left: 50.4%
Rear: 46.9%
Cross: 51.0%

With Driver cross weighted to 50.2%, increases rear to 47.5%

Those #s look really good Nick.

I have a few "weight reduction" mods planned for the front after which I'll get fresh corner balance numbers. Will be a couple months though.
