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

Default Brushless Combo

I was wondering if a Castle Mamba Max Pro with a 5700 kV would be a nice combo for this car.. I mainly want it to go fast
What pinion would I need for speed with this combo, with the standard spur gear?

Took a hit once. The other time it just broke, I think it might have already been broken though.

Default Lipo holders with tape slots

Diggity Designs has released some T4 lipo holders with tape slots. These are used to eliminate the need to wrap tape all around the bottom of the chassis. It will also eliminate unwanted tweak from battery movements. Check them out here -

A couple things

1. Its a soft pack. I wouldn't be running that in a car...specially with lots of sharp carbon around.
2. Likely it won't fit as the pack sits ever so slightly under the top deck. Refer to my photos a few pages ago.

Why 3S? Are you bashing? Seems something like this is a little much for bashing...

@marc

Can't help you on the Castle question other than traditionally I have not seen that combo in an on road TC car.

As for the lipo I would never run a non hard case lipo but to answer your question with enough tape I am sure it would fit but I would not recommend it.

Hope that helps.

Not exactly bashing. I ordered the Mamba Max Pro because I like the Castle stuff. never had problems with it. And the 3s.. Well: I kinda like speedruns a lot. Thats why I wanted to give 3s a try

This is not the right car for speed runs. But if you really have too.....you'll need:

- lola body
- foam tires
- locked diffs
- a closed lot that has been swept (dont even think about doing this on an open public street)

If 6.50 is to much money I think you might be in the wrong hobby.
