2-Suspension
3-Solid Axle and Differential
4-Bulkheads & Drivetrain
5-Driveshaft (ECS & CVD)
6-Front & Rear Suspension
7-Tweak
8-Anti-Roll Bar

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

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.

It think these are for the USGT and VTA classes I would assume. TC wouldn't need as much weight.

My T4'16 is 1300g ready to run. I think the low profile batteries have a lot to do with it.

I was 1320 with orca 6200, revtech 24k, hobbywing and savox. I like the idea of the brass weights but they prob ungodly expensive knowing xray. ill prob pick up the alu chassis before i spend on any of the other weight options with our club moving to black carpet in fall.

I remember having to add 50 grams to craigs aluminum t4 at the last big race i borrowed it heh.

mod cars running 5000-6000 mah batteries will benefit most from it. What tires you run also makes a large difference in weight.

T4 '16 ip 6000 cells, 24K motor, Tekin Gen 2 ESC, Sanwa receiver & Servo, std weight body, Ride wheels & tyres, I have to add 65g to make the 1350g BRCA min weight.

With a Motiv 7800 on Gravity tires I have to add 40g. It was the same with Jacos for Birds. Testing a Motiv 5000 had me adding another 70g. That is with the Avid aluminum chassis. These are also a nice tuning option for weight bias.

They will be excellent for VTA and USGT classes where it is sometimes difficult to find room to add weight.

Running XRAY's aluminum chassis I still had to bolt 70g of weight to the car for mod, so the brass arm mounts (specifically front) would be really convenient

Generally, when I see setups running it, and when I've run it, it's been on big outdoor tracks. On small tracks any advantage it can bring makes the car inconsistent, or at least feel that way due to the quick transitions.
