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)

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.

Yes all it does is add weight and definitely kills corner speed

Appears to be fairly minor updates.

Definitely minor. Anyone who got a '15 recently at a good price would be pretty happy. Add some aftermarket DCJs and you're set.

The motor mount is a pretty simply change (only the lower extension) so if it works effectively it might be a nice upgrade for some.

The integrated ARS mounts are neat when using ARS but look a little clumsy when not. Would have been nice to see a three screw or keyed mount to prevent tweak instead.

The upper and lower deck changes can be achieved with a dremel and a steady hand most likely

Those wheels... EW. What a massive blunder from Xray, image-wise. Makes the whole car look like a cheap-o chinese drift car. Reminds me of the release pictures for the Corally Phi. They had put on huge, uncut foam tires and the car had like a 9mm ride height. It was painful to even look at it.

A competition TC post-2008 is white (dish) rims and shiny rubber, period. You should know the codes, guys... [rant over]

Same wheels as last year but grey not white.

I actually think it is cool to see non dish wheels!

Not orange, but check out Rod Canare's car below - looks tops.

Anyone has a good description of how the new additional motor mount holes influence flex (when to use)?

4 steps of stiffness?

And/or more flex front to rear as the screw fix point moves back/forward of centre.
