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:

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.

Default tire wear

Hi,
when driving my T4 I get i 'ring' around the inner edge of front tire. I keep on driving and the tire opens up along that ring.

I am wondering, is this ring due to something wrong in the setup?

It is mostly the left front tire, we have a clockwise racing track.

Thanks!

How long is it taking you to get those rings?

My first question would be what tyre?
Is pretty normal to see after extended running, but some suffer earlier in their life than others (volante for example).
It can be a result of excessive camber and/or camber change, but if your running normal setups (1-2° camber) then it's most likely tyre related than setup.

Sorry for thread jacking but I'm wondering if anyone of you guys would know if the front spool from a t4 would work in a t1? Also are the drive belts interchangeable?

Not unless you buy a 15/16 style servo mount.

Well carpet season is around the corner , we usually are back to full swing mid Aug... So I'm going to ask the question.
Has anyone give any thought to the new T5 platform ? Not that the 17 is going to be a new platform ... But thinking this 10yr old suspension is ready for a update . cause with all the new cars hitting the market with good reviews it seems this is the most common change ... Upper camber link type "Y" or "V" shaped. Which eliminates all deflection in the suspension which should make the car more consistent thru the corners . might be something to look into for those of you with some 3d printers and the desire to try something new

I would contact your local X-ray dealer and see if they can order the part for you from xray direct.

HiH

Thanks!

I do get a some time driving before it happens.. I drive sorex 36 tires.
I think it is mostly by the manual when it comes to camber settings.
