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

XRA372113 Composite Suspension Arm Front Lower Right Graphite

Spring 4.75 Coils 3.6x6x0.45mm, C=2.0 - Silver (Soft) (2)
XRA372178
Spring 4.05 Coils 3.6x6x0.45mm, C=2.5 - Black (Soft) (2)
XRA373584 Side Spring C=0.6 - Silver (2)
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)

Hey Everyone,

Was looking at picking up this kit and was talking with a few people at the track and they were saying it's a great kit however the front end develops play.

Is this the case for the 2017 kit or was this from previous kits?

Really interested in this car but don't want to buy a parts depot.

Look forward to your input.

Thanks

- Jake

Front end has some play. After fixing it, it's not really much more than other cars.

You can shim the upper arm pins and drag a knife inside them to reduce that play.
You can drag a knife in the eyelets and arm to reduce that play. 4 lines only.
You can use a plastic ball to replace the steel ball to reduce play.

You NEED to have a Hudy 3mm reamer to ream out the plastic ball and kingpin when they are installed.

You'll need to polish the kingpins.

I'm not sure that the play has any effect on the cars performance. But the lack of any kind of stiction sure does.

AE springs fit perfectly fine with the stock holders. Just flip the spring around.

Thanks, Zerodefect.

I've got a well cared for and used 3mm reamer (XB4, XB2, XT2, and T4). It gets a workout a few times a year.

Drag a knife? Like lightly score some lines?

Also since this will be my first time back in 1/12th scale in about 25 years I'll have a few more questions pop up I'm sure.

Does the X12'16 Hiro Seiko screw kit work for the 2017 car?

When you drag a #11 exacto blade across plastic is scores a line into the plastic, but the plastic on each side of the line raises up. That removes play, and still has very little friction.

Like dragging a stick across sand. It's deeper in the middle, but taller at the sides.
