Welcome to the XRAY X12'17 Thread & Wikipost! Here you will find some useful info, tips and tricks as well as setups that are used by several team drivers. Many of us run the X12'17 on high bite carpet and with most US tracks going to the new black CRC carpet, most setups from here out will be developed for those high bite conditions.

Tips & Tricks:
Some racers notice slop developed in the front end over time. One method to reduce/remove this, as pointed out by some of our friends in Europe is to score the inside of the plastic front pivot ball (where the kingpin goes through) with a sharp xacto blade. Usually 4 scores at 12, 3, 6 and 9 will do. Alternative options can be found listed below.

As with any 1/12 pan car, a smooth operating suspension is critical to performance. It is recommended to polish your kingpins & hinge pins using a dremel or a drill and some sort of polish (IE Gravity polish or Mothers Aluminum polish will work). If you find that your suspension has a bind, you may look at using a reamer or drillbit to make sure the holes are clear of any flashing or debris. The only place this may happen is at the upper hingepin, which is 2mm dia.

For stock racing we usually find ourselves looking for a little more steering. One trick that some of the stock drivers have done that seems to help is lowering the graphite plate that the servo & shock mount to. To do this, you will need the 17mm standoffs from VBC and the servo mounts from the 2015 or earlier X12. Be careful that the servo mounts do not sit crooked on the plate when attaching it; a 0.2-0.5mm shim will help ensure it sits perfect on the graphite plate. Part numbers can be found below.

Option Parts to consider:
XRA371220 X12 Foam Bumper
XRA372012 Composite Front Upper Arm Mount Right Graphite

XRA372022 Composite Front Upper Arm Mount Left Graphite

XRA373586 Side Spring C=1.2 - Black (2)
XRA375010 Graphite Rear Axle Shaft - highly recommended
XRA378094 Shock Spring C=2.1 Black

Lowered Graphite Plate:
B-02-VBC5005
XRA376255-O Alu Servo Mount - Orange (2)

How did you get ride height? I'm struggling with 40mm tyres.

I found the front end to still have an incredible amount of slop. I reshimmed the uper arm and it took care of part of it, but the king pin still has significant movement on the pivot balls. Looks like AE parts are still needed: AE steering blocks, AE pivot balls, AE upper arm eyelet, and AE king pins.

My knuckle and lower pivot ball needed a Hudy 3mm reamer to even get close to letting the hinge pin slide freely. So they obviously fixed that. No play at all there.

I polished the kingpins to a mirror finish with no play in the knuckle or lower ball.

If you run a plastic pivot ball in the top arm eyelet, I think that'll get rid of that play in the ball, but it'll need reamed like the bottom one. Or you can slice a #11 knife inside the eyelet to raise up a ridge to remove play with the metal ball.

The steering block already has setscrews holding the upper hinge pin, no slop there.

Seems like the upper arm is a bit loose, but after the tightening up the upper pivot ball play, I don't think the play in the upper arm is too much. A few small shims might help.

Has anyone even gone faster after removing the slop? It's not much on my car. A perfectly free front end is going to have a little. I have to ream and fit AE parts as well, and then it has some slop, although less.

Xray used to, XR372085

Was on the XII, not sure if the front plastics have changed position since then so I don't know if it will still fit.

Having said that, team drivers never fit them as the front end of the Xray is pretty stiff.

XR372086 was listed as a front brace for the x12 it does not fit the 2016 car so probably not the 2017 either.

If I'm not mistaken the front bulkheads are closer together compared to the XII, so the brace will fit, it just needs some work to make it shorter and to re-drill the hole

I've found this to be true on the '17. Also had to ream my steering blocks, and of course polished the kingpins. I've not tried the plastic pivot ball in the upper eyelet yet but agree that would probably be better. I feel the new front end has just the same amount of slop as my front end with AE parts, and my front end with Xenon parts. Some slop is necessary for things to move freely. It's a very small window though.
