Yeah I know what bump steer is, just didn't realise it was so easy to cure. I wonder why they don't just build the extra 6mm into the original design. Good tip, cheers!

we've been doing this mod to all of out cars that they fit in for a long time. less leakage and smooth as butter. Makes AE V2 shocks almost bareable.

Great - thanks.
I will try those out.
I normally soak the o-rings with green slime in a small plastic bag for a few minutes.
Are you using green slime as well?

Well you "could" build it in, but then you wouldn't have all the adjustability that the 210 offers. As you change the caster inserts in the C hubs, the bumpsteer then needs to be changed as well. Why, because the end of the steering arm gets lower with more recline and higher with less. You want the tie-rod for the steering to be as close to parallel to the arm as possible, hard to do because the arm has a big bend in it! Imagine running the 35deg caster position, would need even more spacers

If you're happy with the 30deg (I think it's spot on) you can do as other have done and move the rack to the underside of the rocker arms, this reduces the amount of spacers on the outer end...

Note that I used the term V2 and bareable in the same sentence

Shocks feel pretty good at the moment, no leaks at all, before they would leak just sitting on the table.

Didnt think about that one, that's another good solution to the problem.

Does anybody know if the Delrin suspension bushing option on the RB5 work on the 210? If so that would be a really good upgrade as well, metal to metal doesnt quite tickle my fancy when it comes to suspension parts.

Not sure about the K ones but I know the tamiya ones fit like a glove. Before guys were upgrading to the alum block I was handing them out like candy on Halloween! Plus they have a nice coating on them that makes them "oh so smooth"

Default shock oils

I'm wondering about shock oils and am currently using the 4-hole pistons (I think that's 1.3 and 1.2) with losi oils anywhere in the range of 25 to 37.5. It's a high-speed, medium-traction indoor clay track that's kinda bumpy with a few big jumps. Currently running 30wt oil front and back.

Any thoughts on what others are currently using for oils? I'm running RM with a full stick battery pack.
