Quick question, how do you guys get so much weight in your cars when you take so much wood off? Is it better to rout out a section on the bottom of the car and weight that area (length-wise), or to drill holes and put as much weight in as possible, width-wise?

I do the same as Emerson with the dremel. i pour my lead which is a little tricky until you get the hang of it. seems i pour more to one side, but you can always drill it out to balance the car.

I use 1" diameter Tungsten Discs a little less than 1/2" thick. No pouring, no routing, easy to locate the CM with pin point accuracy and there is nothing out there with the density to concentrate the weight into a small area as these!
Just drill a hole 1" in diameter drop the disc in and set to whatever height you want it off of the track. It can ride as low or as high as you want it too. Locate it just in front of the rear axle or where ever you like. Easier to install than any weight I have used.
I have used lead for almost 6 years and the 3/8" tungsten cylinders for 2 years and my cars with the 1" tungsten discs are much faster than I was ever able to acheive with the lead or the 3/8" Tungsten cylinders.
I have poured lead, used lead worms, etc, etc, and could never achieve the speed I have with the 1" diameter Tungsten discs. Lead is just not dense enough. I have even used tungsten plate and the 1" diameter disc is better. Just my .02 cents worth.

I have a question for you? How much do these 1" Tungsten disc's weigh?? How many onces each?? or Grams?? The Discs that are 1" in Diameter and Slightly less than 1/2" thick weigh 4.2 oz. They are 99.95% Pure Tungsten 19.3 g/cm. The only materials more dense would be Rhenium and Osmium which are very expensive. I believe 4.20 oz of lead would take up almost twice the space. Any other questions? ;D ?? Racing

I just purchsed four of these disks. They were decently priced. I will try and post a picture of the car body that we made for the pack race. You can PM me if you want contact information for the disks.

Subrscribing, AND, Do you have a picture of the attachments you use on your dremel?
I have had THe same Dremel for about 7-8 years now, and it may be time to get a new one.
For now, I use a Mortising attachement on my drill press.
