All a-arms have the shock mounting holes moved 0.3mm outwards to match the new geometry of the shock towers.
The front arms are also redesigned to move the shock further forward to increase overall steering.
'16 arms also have the screw holes for the carbon plates removed to increase overall strength. Optional graphite arms are being used instead.
The older '15 arms will still fit but will alter the shock geometry as well as reduce overall steering.

I would be very secure running an arm with 0.3mm off in the shock mounting hole, if I need a replacement arm from my current stash..

My '16 kit will be here tomorrow. Was wondering if any new piston options came with the car and if so what is everyone using for high grip clay? My 2015 has the Avid Pistons all the way around but wanted to try the kit as is before modifying. Planning to go F-7k C-60k R-5k for oils (Center dif coming out of the '15) as was my setup on the 15 car. Presently oil is 42.5F 37.5R.

I run +.75mm FR and +1.5mm in the rear with TLR 22-4 wheels. The 9 of the exotek seems way too wide. It also appears that on the '16 they gave the front axles some extra threads for everyone running wider hexs, a needed touch that is much appreciated.
The new shocks build exactly the same but seem smoother. Mine feel perfect, stock pistons and all.
A couple things I noticed while building the kit. When building the bell cranks it has you put the two arms one way on the steering plate, and then the next picture they're reversed. Also, kinda a pain, is that they have you put in the spur gear in one step, and then 10 steps later you have to take it out to put in the wire cover. Other than that, the manual is perfect and build is amazing.
I'm never sure how they are going to make the car better each year, but somehow they keep doing it. Can't wait to drive this car.

The .75 front and 1.5 rear. How does that match up to the exotek hex? Xray is offset, exotek is total width. How do you map the two?

#365353 0mm (2pcs) = 4.6mm (same width as standard 14mm wheel hexes)
#365354 -0.75mm (2pcs) = 3.8mm
#365355 +0.75mm (1 stripe)(2pcs) = 5.3mm
#365356 +1.5mm (2 stripe)(2pcs) = 6.1mm
#365357 +2.25mm (3 stripe)(2pcs) = 6.8mm
#365355 +3.00mm (4 stripe)(2pcs) = 7.6mm
The small inner flange that goes towards the bearing are not included in the measurements .
This flange adds 0.3mm on all the above numbers.
When using the softer optional Xray 12mm hex wheels we use:
Front: #365355 +0.75mm (1 stripe)(2pcs) = 5.3mm
Rear: #365356 +1.5mm (2 stripe)(2pcs) = 6.1mm

The only other wheel I have here now is the new slim JConcepts Mono front wheel for B5/RB6 that we got at the Worlds to test on the XB2.
This is meant to be used with the JConcepts Swaggers front tire for astro/carpet.
I have however ordered JConcepts Mono front and rear wheels in different offsets on Malin's next shipment of JConcept items to see if I can find suitable Xray 12mm hexes for both the XB4 and the upcoming XB2.
I have all the different hexes here so it's just a matter of finding the time once the wheels get here.
Reason for us using the Xray 12mm wheels is they give us a greater range of track width adjustment combined with the Xray wheel hexes and the wheels are softer as well to provide more grip and a bit of cushioning when landing jumps…….and especially on flat landings which are more and more common on our astro and carpet tracks.
