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..

Does any one no if the shocks have been changed on the 16 or are they just different colour shock bodies.

Honestly they seem a lot smoother compared to my 15 car. The new color of the shock bodies look way better over the old black bodies IMO.

I haven't built the shocks yet but to look at the new ones look heaps better but was wondering if its cosmetic or they are a new design, i suppose if they were new it would have been listed in the 16 specs but they don't mention upgraded shocks.

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.

There are different exotek hex sizes for 12mm. 7, 9, and 9.5mm I think. Which size matches with the standard xray hex width?

For front, which hex do I need that's adaptable to most front 4wd wheels?

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?

The +.75 is about 4.5mm wide, the 1.5 is a little over 5mm wide.

Exotek min for the rear is 7mm I think. What is the stock width for the xray 14mm hex?

#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

thanks Bent... Why is the exotek widths so much larger than the xray widths?

basically, i just want to use 12mm hex wheels, but keep the same width as the standard. Unless there's a huge benefit using some other hex size.

I do not know to be honest.

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.
