4-Bulkheads & Drivetrain
5-Driveshaft (ECS & CVD)

New Graphite Hubs:
Xray have recently released some additional Graphite hubs for the T4 lineup. The 4° Graphite C-Hub has been out for some time and is known to improve steering on entry, and in general makes the car turn better. This has been the go-to c-hub on asphalt for many on the Xray team, though it is not needed on high bite carpet. The Graphite rear hub tends to make the car more stable, especially on corner entry. We are still working on gathering input on the new Graphite steering block, but for the moment feel that it should improve steering response. All Graphite parts are approximately 1g lighter than the Hard or Medium options.

Option Parts to consider:
XRA301196 T4 Graphite Upper Deck 1.6mm V2
XRA301226 Foam Bumper – Hard - highly recommend
XRA302165 Composite Front Suspension Arm 2-Hole – Hard
XRA302169 Composite Front Suspension Arm 1-Hole – Graphite
XRA302803 1.3mm Front Anti-Roll Bar
XRA303169 Composite Rear Suspension Arm 1-Hole – Graphite
XRA303802 1.2mm Rear Anti-Roll Bar
XRA305137 Steel Solid Axle Driveshaft Adapters - HUDY Spring Steel - highly recommend
XRA305242 Composite Drive Shaft Replacement Cap 3.5mm – Orange – Strong (QTY 4)
XRA305351 Aluminum Wheel Hub – Offset “-0.75mm” – Black (QTY 2)
XRA306191 T4 Graphite + Aluminum Fully Adjustable Battery Holder
XRA308264 4S Spring-Set Progressive C=2.5-2.8 (QTY 2)
XRA308276 4S Spring-Set C=2.7 (QTY 2)
XRA308286 4S Spring-Set C=2.6 (QTY 2)
Specific to Asphalt:
XRA302383 Composite C-Hub Right – 4* - Graphite (ECS)
XRA302384 Composite C-Hub Left – 4* - Graphite (ECS)
XRA308039 Aluminum Progressive Shock System – Set (QTY 2)

Specific to Carpet:

XRA301141 T4 Aluminum Flex Chassis 2mm
XRA302375 Composite C-Hub Right – 6* - Hard ***Modification may be required if they don't have the "ECS" stamp.

XRA302376 Composite C-Hub Left – 6* - Hard ***Modification may be required if they don't have the "ECS" stamp.

XRA303711-O Aluminum Rear Lower Suspension Holder – Front – RF

Even after adding the 30g XRay weight, I still needed 50g...SUPER lightweight car. It was SOOO good though.


Floating servo mount or no?

I build my car with the plate on it in case I want to try it but I don't run it. Almost everyone else on the Xray team used it at Birds though.

Can anyone confirm that the 15 aluminum chassis fits on 16 without any modification?
Is it a direct bolt-on?

i replaced my 15 carbon chassis with the 16 chassis. the only difference i saw were a couple extra holes in the 16 chassis to accomodate the new motor mount piece that allows you to adjust rear flex a bit but if you're using the aluminum chassis, that flex adjustment probably isn't a concern

Yea that adjustment is huge on even an alumn chassis! IT changes where the chassis flexes at when you move the screws around.

Just got back home from TITC 2016.

Stig Xray gave me a prototype part the team is working on, new drive shaft plastic caps which is harder than the standard. To be released soon.

Just want to throw in a good word for Avid's new adjustable top deck. Team guys have been testing for a while with good results, got my production version before this past weekend. Awesome piece, the on the fly ability to change flex is very useful. I found myself running in the 1 dot position with the rear post and the rear 2 layshaft screws in. On the new CRC carpet I was really impressed, great initial reaction and improved stability.

Now if they would just get aluminum chassis back in stock I'd be all set... Glad to hear the new top deck works well, pretty neat design. Can't wait to try it out!

I can second this. It's an impressive piece and works exactly as advertised and then some!

Can anyone share some experience with the flex settings on the motor mount ?
I think it is unclearly documented and I looked up all the possible X-ray setup book, they did it mention anything about.
I do see the settings are being played by X-ray team players, but they are far different from each other.

I need some help to set it according to my like, plz help.

Screw more towards front: shorter flex - more reactive, faster direction change, more steering.

Screw more towards rear: longer flex - less reactive, more side bite, more overall grip, less initial steering.

All screws: the most reactive setting for high grip tracks only.
