Keeping the interior ?


#1

I notice everyone has it removed but i saw several folks puting like dumbell weights in the passanger side wouldnt that negate the weight savings of removing the interior ? and could you be competetive with an interior. I’m assuming the added wieghts are balast to negate the offset of the driver,.

Being "larger" I don’t need to add weight. Thank Carter for weight limits WITH the driver onboard!!!

But think about this. If you can remove weight in the ends of the car or from way up high (sunroof motors etc) and then replace the lost weight in an advantageous place such as down low in the center of the car you have lowered the center of gravity and reduced the polar moment of inertia.

Both good things.

You also remove lots of stuff that burns and gives off nasty fumes in the event of a major problem.

By the way. I wouldn’t take any of the weight out of your trunk until you corner weight the car. Car may end up nose heavy and you may wish it still had weight back there…don’t ask me how I know!!!

good point about the center of gravity. i am a bit lighter at 166 currently. So i guess you cant be to light, how does one go about getting on a scale to verify the weight for competition , it would stink to get the car all ready and fully gutted only to come up 200 pounds too light :stuck_out_tongue:

After calling a few garages to track down a scale, someone recommended going to the dump - they charge you per pound of what you drop off by weighing you on the way in & on the way out. I went through the line, got my weight on the way in & then pulled a U-turn. The operator looked confused as hell as I pulled up in my little e30, in line with a bunch of dumptrucks & pickups.

I never would’ve thought to do this on my own, but it worked!

Any good race shop (don’t rule out circle track guys) can weigh your car. Get a baseline weight and then start pulling things out. Weight each item on a bathroom scale and you’ll have a good idea about how it affects the weight. Also note the fuel level so you can keep it consistent.

As Steve says, the "city dump scale" idea works and some truck stops have scales too.

You want to really drive the scale guys crazy?

Pull on until your rears are just off the platform. Get weight.

Pull forward until you are 100% on the platform. Get weight.

Pull forward until the fronts are just off the platform. Get weight.

I do this at the lucj stone plant where I buy gravel and stuff so they just put up with me.

Now you can get a percentage front and rear. This is much more useful as you attack weight removal. If you are 70/30 front heavy don’t TOUCH anything in the rear of the car!!!

If you can get closer to 50/50 (probably impossible wit these cars) you will be much happier.

Bring the car to one of the MASA Mid-Atlantic events anc come on over to the tech shed to find out when we might set up the scales and be REAL NICE to the tech folks and if it is not impound time or anything crazy, you can get weighed.

So, then conceivably, I could get my car weighed while at the SP MC HPDE-2 in Sept?

The point about fire is a very good one. Fumes and flames… Eish-

Jon, we have GTPerformance around the corner, and Turbo Performance Center is down near Linthicum.

You and I could also go halves on a scale set. There might be cheaper ones out there but I found this real quick at Pegasus. http://www.pegasusautoracing.com/ProductDetails.asp?RecId=2485

I might need a wrenching buddy this weekend, I need to put a radiator in.
