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.

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

Do the kits come with the new CV driveshafts now? That would be nice.

Other than that perhaps a one piece (Yokomo style, I mean) motor mount?

Just hope the shocks/springs, arms, diff/spools and swaybars stay the same.....The ARS could be an option sold seperately, and the ECS's could be standard.

I asked Hagberg this direct at AOC a few weeks back. He said he wasn't sure what could be an inclusion as he wasn't running any prototype parts and he wasn't aware of anything in the pipeline.

He laughed when I suggested maybe PSS shocks!

+1, the ARS is rarely used (only at the occasional track), but most drivers use ECSs. I don't imagine they cost much more to manufacture than standard shafts.

This time a 2016 version is not neccessary (in my opinion).
Aftermarket tuning parts from Spec-R, for example the motor mount, made a difference in feeling, but many drivers returned to the original.
What could be an improvement are shortened Spur gear bulkheads. Other than that and the above mentioned ECS the car is nearly perfect. Maybe a material change for the shock bladders would be nice as the swell quite fast.

I am not sure if these small improvements would justify a 2016 version. Lets see what they have in the pipeline...

I would rather let the PSS shock inserts stay an option part to give way for some of the more "permanent" upgrades, like alu end spring cups, carbon front bumper, alu steering etc.

I think the average racer would be more happy with these upgrades than option parts that may or may not work in all conditions.

I think including parts where Xray/dealers can make some money afterwards would be starkly in contrast to their business model!

There is no need for them to come out with a shaft car. The ETS series has shown the shaft vs belt debate playout on multiple tracks and the results speak for themselves..

I just ask that they seriously consider including the new ecs shafts in the kit WITHOUT increasing kit price.

I want pillow balls inside the suspension mounts. My RX4-13 was still faster than my '14/15 car with the only difference being the suspension mounts. The car has much more steering when used with the pillow balls.

I'll play. How about a T4'16 carpet edition that includes the following:

Aluminum chassis on par with aftermarket options
Thicker/harder top deck
HD ECS
Graphite arms, with 2 hole in front
Solid servo mount that doesn't extend beyond the back of a shorty servo (ie RADTEC)
Xray's sweet battery retaining system
Solid R/F, split F/R blocks (opposite of current option)
No ARS, spend that money on other upgrades
