Gutting rear interior like the ACR saves 10 5 lbs

[Arizona Vipers]

Just like the subject says, I removed everything in my '13 that is not installed by the factory in the ACR. All carpets, insulation, moldings and the speakers. It saves 10.5 lbs if anyone is interested.
Everything is so light on these cars, it's hard to get weight off them.

I took the engine and transmission out of mine and it is much lighter.

I wonder how much weight could be save with some carbon fiber Tillet seats

[ViperGeorge]

Arizona, how much weight have you been able to remove?

[slowhatch]

I would have kept all of that in, and just installed a lithium battery like the DSE offering, to save twice that weight.

[TheStig]

Or I can stop going to Arby's everyday lol

[kriskyk]

I believe he already has a lithium battery installes

The factory seats are 54lbs. You can get a race seat around 15 lbs, but add another 10-12 lbs for mounting plate and mounts, and if you want it adjustable another 8 lbs or so.

My car is 2980-3000 depending on which tires I'm running. And that includes the 75lbs of ACR aero.

How about both? lol

[ForTehNguyen]

can go to the gym and save more weight. However, I've been lifting weights and gained 15#. Viper is slower as a result

My car is 2780-3000 depending on which tires I'm running. And that includes the 75lbs of ACR aero.

Wow..what all have you removed/changed to get to 2780lbs?

It's not a full race Halo seat but tillets carbon seat with brackets are about 10lbs together, that could be almost 100lbs deficit sans a passenger seat

[Snorman]

If you were really serious about weight reduction, you'd get one of these.
And use it. A lot.

An FIA approved mounting plate is over 10 lbs alone. You can get the side brackets down to 2lbs. And if you want it adjustable that's another 10 lbs per side.

Oops I mean 2980. There's no way possible to get these cars below 2800 even full gutted.

I was wondering how the tires would swing it 220#....damn monster truck tires haha

[slowhatch]

How about both? lol

Haha yes! I can't imagine how absolutely sick your car must be on track at 3000lbs, full ACRE aero, 9L, etc. Must be absolutely unstoppable.

HAHAHAH Yeah. For the record Pirelli slicks are 44 POUNDS LESS than Hoosiers. And Hoosiers are already lighter than street tires and MUCH lighter than Kumhos.

I'm probably just not understanding, but couldn't you just anchor aftermarket seats to the factory mounts and be just as safe or a bit safer (fixed back seat) than the OEM/factory seat?

How? With bracket extensions? This is not that part of the car you want to skimp on to save a few pounds.
This is the company that makes almost every mounting plate you'll find in a race car- http://www.plantedtechnology.com
They don't make a Gen 5 kit yet. You need a plate like this, then the side brackets as well which are 2-4 lbs minimum which are sold by the seat manufacturer. And as I said above the sliding/adjustable kits weigh even more.
Through my research, with the lightest seats money can buy you are gonna lose about 25 lbs max. I'm going to go with this seat-

It weighs 16.5 lbs, I'm going to do the fixed setup so that will save some weight but I'll still end up at about 30 lbs total vs the 54lbs factory setup. You wont be able to get much lighter than that. If you are a very small man and can get the medium seats, that will save another pound. For road racing this weight is not as important as elsewhere as it is down low and near center of the car.

Ah ok makes more sense now, I figured I was just completely missing something
