I also coat the mitre gears and ring and pinion with Finishline ceramic dry lube (cycling product) keeps the drive line in great condition

I just measured the stock track width and its 180mm .... is that a good spot for a tub chassis or has anyone found a better width? My indoor cars are about 185mm width but just curious for asphalt.

Thanks.

The width can be changed with the suspension blocks. The stock kit is using A/A block in front. If you go to C/C for instance, you'll be closer to 183mm

Do you mean biggest pinion? If you buy the new hop up gear adapter, the biggest spur is a 52t. In running that with a 72t spur.

Appreciate that. One more question if you know, whats the XC vs C difference on the blocks mean? Or better yet is there a chart some where explaing the differences? That would be even better.

Thanks again.

No I mean spur gear, I need a gear ratios of 7.6 for my small carpet track, I have got in 48dp 67t spur and 22t pinion which give me about 7.6,but can not get the pinion close to the spur gear so any help would be appreciated.

It will fit any sized spur you like.

The manual has some ratios listed in the back.

What on earth are you running that needs a 7.60 FDR?

The kit parts give you a FDR at like 6.81.

I'd get out the manual, and look at the gear chart, and use whatever sized spur comes in the kit.

The X marked blocks are narrower than ones that are marked just A, B. For example, XC is narrower than XB.
