As close to zero as possible

Never liked running shocks with a lot of rebound.

Hmmm….I will have to check mine to see if it's modified then.

It's a few years old and I can't remember doing any modifications to it…..but then again I'm getting old

I run 1M on a medium bite clay track... and honestly, I doubt I'll change it. I don't have any issues with it, and I don't think going less will solve my problems. I know of another driver running 100K or 60K in his center diff, but I think that's ridiculously low.

My understanding from way back when running an NT1, where we ran 150K and 60K diffs was that the smaller diffs needed thicker fluid due to less rotating mass, especially when we started to use composite gears within the diffs.

Thats because they haven't been officially released yet, but they should be ready to order by distributors any day now (if not already) and in stock soon.

Wow, just ran today with Coelho's world setup on high bite clay and it's excellent, like driving a plush touring car.

We usually run 1.0, 1.1 or 1.2 in low traction conditions.

For medium traction we go as "high" as 1.4mm.

Look at the swaybars as a tool that help you run the suspension softer and more plush yet keeping it stable enough to push and go harder in the corners and higher traction parts of the track

If you build them correctly there are no issues.

Soak the o-rings in the shock oil before assembly.

Loosen the shock bottom cap before screwing the shock shaft through the o-rings.

Do NOT push the shock shaft through the o-rings as this will damage them.

I have a '13 car and I have never had issue with the shocks even though I've heard about it since the beginning of the thread. I'm not sure why some do or don't but mine are good and I build them just like all shocks. Take your time, be sure not to tear the O-rings and don't over tighten anything.

My shocks have never leaked. When built properly they are great.

Looking at AMain for driveshaft pins...

Search for PN# 980210 and you get two matches:

2x10 pins & 2x9.8 polished chrome pins.

Which should I get for the XB416?
