This is with closed cells all around. It is with the Triad which is light and an AL pinion but how much weight am I really saving with the AL pinion? A couple of grams maybe. Oh yea this one is with a Solar D770 which is pretty light...and the transponder isn't in the car...but again, that's only another 5g (just weighed the one from the mod car).

Ok so where do I add the weight? 10g in each corner of the car? Try to get the balance perfect? Slap it in the tray? And if the answer is slap it in the tray then what's the point of running shorties?

The point of the shorty is to lighten the car and you can always add weight back again to get it "right". And put it where you want. You are about 60 grams lighter than me, which is a lot. Considering you have weight added to the car and the centering kit. I also have the avid, but I didnt do alum topshaft, alum bones or alum pinion. Its very curious, make sure you actually have the ballast in, lol.

Here's what i am running:

Servo: XP DS1015
RX: M11x rx
Speed control: LRP Flow
motor: Reedy Mach 2
Battery: #602 4100 shorty pack Reedy

Using those with no weight added and running slicks, my car was just at 1460. I added 7g weights in each rear triangle, the ballast weight and a 14g in the front of the battery tray and the car weighed about 1504-1505.

Are you running any Aluminum parts in the drive train rather than steel?
