I think you just grab a BD7 front spool drive cups from the BD7 2016 which is D-046


96T spur is the way to go I found to cover you and you need to grab the Option Top Deck B8-003NB to allow bigger pinions for the stock classes gearing FDRs.


As for a chart you might have to find some program that spits out an excel table after inputting your 1.7 internal drive ratio.
I prefer to run the largest spur possible to attain the ratio I desire. it is my opinion that the car accels easier and as increased natural braking might also help with that pesky stripping issue some of ya'll are having that I'm not

I'm looking for alternative adjustable body mounts. The O-ring on the Yokomo ones are on the outside and crack/break easily.

Xray ones are the best, pretty tight, but don't fit the Yokomo body post holes.

Any one?

Use Xray body posts and then you can use the Xray adjustable body mounts.

Arc adjustable posts are the best. Made out of plastic and is wider, had a set for two years no issues.

I just picked up a BD8. It ran just as fast as my xray T4 17 without any setup changes, nice. However, I had a couple observations:
1. when I push down slightly on the rear belt. I see that pulley area of the motor mount flexing back. Is this normal?
2. I guess I should have know this but the pulley cams move under load unless you put set screws in the inner link mount on the top of the bulkhead. With aluminum cams, do you have to do this with set screws or not?

Also does anyone had a good setup for black carpet indoors I can use for starters?

Thanks! The car is nice!

Where can I get some? I noticed when I tighten down the grub screws to make sure they don't spin around on me it seems to affect the free spin on the whole drive train as it pressures the bearing.

The aluminium diff cams won't necessarily eliminate the spinning. Best thing is to use a little threadlock in the grub screw and just nip it down slightly on the cam. That's what I have done with the standard plastic cams and they've never moved on me in 13.5 blinky. Otherwise use the BD7 plastic holders and they definitely won't spin.

The aluminum diff cams are trash, they will spin on you, stock plastics are the best.
