Is there anyway to run thicker front hexes?

Why the 6 can move the front axle +/-3mm in or out?!

usually due to 3rd party wheel hex depth. K fronts have a shallow hex.

I have a few B4.2 wheels left over which I would like to use up.

Alternatively you can use the rb5 axles which you can put your own hex on.

That's what I thought, thanks!

On another note: Did someone compile a list of screws for the RB6? I could swear Bob Barry had a list going...

Reason I mentioned you can move the axle in or out is I usually run pl front wheels which have a deep hex. I just move the axle out and all is good by just flipping the spacers. Just saying you can get the proper width to run almost any front wheel just need to figure out what spacers need to go where to achieve it without spending the cheddar for different hexs.

So.... You can run b4.2 front and rears on the RB6? Sorry I am just confused

Yes you can but the rears will be slightly narrower overall by just a hair. If its an issue you can go with the longer rear axles with three lines for full adjustability front and rear.

How is the rear track adjusted? I see the three lines but unsure on how to adjust the width.

Just ordered a car today that I will pick up and start building tomorrow. Anyone have a good set up for stock mid motor? I'm replacing a b4.2 with my new rb6

Can't get good consistent traction with my b4.2 at my home track which is hard pack with a bit of fine fluff. Took it to a clay tack though and it was good. Thought about an xfactory car just got tired of waiting

What are the differences between the different arms, hubs and other little bits?
Like "type B" hubs, "middle arms", "type B" pivot block etc...
Also the difference between normal flat rear arms and the gulwing ones?
