Quick question guys , what gearing do u guys use for mod ? Pinion and spur !

48 pitch 72 spur 18 pinion.
Why you might ask? I have killed 4 spurs in a weekend running mod.

96 spur 23 pinion if you are dead set on running 64 pitch but I would recommend against it.

why would u not recommend it ?

Pretty sure they explained that in their first paragraph.

just use these

local hardware stores like ace hardware have pinecar tungsten weights

I haven't seen any hardware stores supporting our hobby. Ill pay the extra few bucks knowing its going towards the hobby in some way. But I get it most people are cheap.

any store that sells pinecar derby will have those weights

The Mugen ones are nice because theyre narrow and can fit centerline with the belt.
Erics are nice because they can carry more weight with a little more real estate on the car.
PineWood Derby weights are nice for the fine tuning in small areas.

With ROAR moving up to 40mm fans, are there any that are "better" than the rest? Are you guys using the fan mount with the car or shroud/tape to the chassis?

I use the 1 upRacing 40mm fan with the fan shroud! Cant go wrong with 1 UpRacing products.

These arent pinewood derby car weights. I have them made to those sizes as they fit better than most generic pinewood ones. Some of the pinewood ones work OK but round ones and such are a pain. The tiny small square ones I find all over our track where people loose them. I used to use them but would glue 4 of them together and then tape in so it had more area to stick.

EA

got some off amazon and a calibration weight set to figure how much and where to add the weight.

None taken.
