This is my first attempt at "balancing" a car. I probably wouldn't have bothered, but my car is ~90g under weight and I just wanted to optimize the placement of that weight.
The attached images show how I have balanced the car. The scales show that the rear is ~10g unbalanced. To get it to balance out completely I had to add ~60g of weights next to the motor bell end. This also shows nicely perfect balance by suspending the car in air using two picks, one on the rear wing mount center screw (unique to the 3.0) and one on the center of the front bulk head, just above the bumper.
Not sure if anyone has been this particular about left to right balance, but I thought I would give it a try.

Can you post a pic with all 4 sides of the car on scales?
The pick method does not follow scientific method, so please move away from that.
Also, where is your battery strap, and where is your body? Both affect weight big time.

Left to Right Balance
I'll be looking into it.
I never thought of it before but the mass of the motor plate, spur-pinion & cover introduce an off-center weight in any buggy.
Looking at PIHGUAM1's balance (post #1493, pg 100) the ESC and wires are on the left side which may help to balance out the car.
Has anyone check the cars balance without electrics in? I will try to see how my car balances like this.

I'm going out on a limb here and say you have something very wrong happening here.

Front = 599.8g
Total = 1407.1g
Three changes from stock that would effect weight:
- MIP Pucks
- Titanium Turnbuckles
- Velcro instead of the battery strap (which now I find out removing the battery strap is not recommended)
Also I am using a x-light shorty (147g) (~50g less than standard shorties)
And the Tekin G2 Stock ESC and GEN3 motor is light as they get (22g + 158g)

Unfortunately, I only have two scales, so I guess I should get two more to do this correctly.
Rear = 807.3g
Front = 599.8g
Total = 1407.1g
Three changes from stock that would effect weight:
- MIP Pucks
- Titanium Turnbuckles
- Velcro instead of the battery strap (which now I find out removing the battery strap is not recommended)

So, I'd recommend popping in a normal shorty or putting all the stock stuff back on. Also, have you calibrated your scales? Normally those little ones can be be off several grams and need to be calibrated.

i bought these tires and they came in today.
http://www.amainhobbies.com/rc-cars-...61574?v=274735
the foams inside seem to wide and it it pushing the tire walls out. am i supposed to cut the foam to get it to fit better? If not, how do i get it so they are completely round. They currently done lay flat so if i were to glue them, they would wobble
any help is appreciated

I question the battery brace. In its stock form with my batteries it takes a fair amount of pressure to get it to the point where the clips can be installed. So much so that when you place steel ruler against the chassis you can noticeably see daylight under the back part of the chassis. This is the reason i placed 1mm spacers under the waterfall and went to a thumb screw type of hold down and this completely solved the chassis flex i was seeing. I understand what you are referring to but you definitely dont want to bow your chassis from the start. All lipos are a bit different so i can understand the need to make adjustments like i had to. Be nice to see an upgrade to an adjustable battery hold down in the future. I hate the battery taping setup.

I just watched Jason Snyders review of the 3.0 and he claims that the rear camber block is a bit weak....has anyone found the same issue?...and if so is there a replacement part. I haven't had the privilege to run mine yet as its a little snowy here in the great white north.
