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)

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

Tough call there I think because the shape also effects how it works.

But, I have the Reflex allow chassis, the old shape RX4 alloy chassis and a TT chassis. The Reflex 2016 alloy feels a bit stiffer overall than the TT but I do think the new front cutout shape adds a little front flex. I'm going to guess that the new Reflex 2016 allow is a little softer than the Xray Hard alloy.

The new alloy chassis is softer than the XRAY Hard, but perhaps stiffer than our old one. The flex has been isolated to the front and rear bulkheads like on the CF chassis and the flutes have become cut-outs, however we reduced them from 3 flutes to only 2. I actually have a few guys testing them on medium grip asphalt and they really like them. The guys that have tested them are not necessarily top level guys, but sometimes I like middle of the pack guys' feedback better than fast guys that can make anything work.

I am waiting on a fresh batch of aluminum to release them to the public, but I do have pictures that just need to be processed so I can post them for you guys to see it. The alloy chassis was actually developed in cooperation with quite a few guys feedback including a certain National champion that was instrumental to getting it right. I am very confident in the performance of it as it seems everyone that tried it went faster than with it than with other brand offerings on the black carpet.

Too bad im broke ass from building a new nt1, or id try to get one for the august long weekend race in vancouver...
I ran stock cf at irocc speed weekend and though the car was fast, i wished it was just a little bit sharper. The hard chassis might have been too much but a medium harness would have been great.
Not sure how id rate compared to your testers.... we have a couple local team xray guys i can keep pace with.

Need a little help...I have two Xray T4 2016 and the rear upright keeps getting stripped out on both cars ! The link pops out as the hole gets super enlarged. Any ideas what is causing this?

Two things to try. Use a longer ball stud (I think kit is 8mm.. try 10), and put a grub screw in the unused hole to help stop the plastic flexing and moving.

After getting fed up with constantly having to add more and more foam to the front of my TC to support the nose of the body and keep it from rubbing Ive come up with a solution. The new bumper has 3 extensions built into the bumper that fully support the nose of the body at 3 points and keep it from dragging the track allowing you to run the body lower in the front. They are designed to fit the Xray perfectly. They also fit the Awesomatix, TC7 and Gizmo cars although some minor trimming may be required around the back edge where it mounts to the hard bumper. They are designed to have the body mounted 6mm forward if you mount it right up against the bumper taking out a lot of guess work as to how far forward to mount your body for maximum steering and performance. There are two versions. A solid foam (recommended for carpet or cut version with inserts) version and a Cut out foam (recommended for asphalt without the inserts) version. The solid one weighs in at 5.15grams. The Cut bumper weighs in at 4.25 grams. The stock soft Xray foam bumper weighs 4 grams. These are made from a lot more dense foam than the stock bumper but still light weight. More weight in the front (super heavy bumpers) will take away steering on the racetrack!

These were tested at the Reedy race with no issues and 100% positive feedback from everyone.

Hi Guys, I hope i'm in the right place. I just got myself one of these. Will be building it over the weekend. What are the popular hop-ups and spare parts I need to have. Will be running on asphalt outdoors, bumby tight track. Any help will be appreciated. Thanks.

I don't think there are any must have upgrades for asphalt but I do like to run the hard bumper (check out EA's new one) and the graphite upper bumper support.

Spares on Asphalt:
  • Steering blocks
  • C-huibs
  • C-hub bushings
  • Rear hubs
  • belts if the track has any pebbles on it

Ill also add a replacement screw kit, as out of the box Xray doesn't really supply any spare screws. Many people upgrade to the Hiro Seiko Titanium & aluminum screw kit, or there are also manufacturers who sell kits that replace every screw with a titanium option.

I'd highly suggest getting a 1.3f and 1.2r roll bar and a set of the 2.5-2.8 springs for the front of your car. Finally, a 2.6 rear spring sometimes wakes the car up quite a bit, if you need something more responsive or need more grip out of the corner.

+1 for the other responses...

Don't forget a good chassis protector too! I personally don't use the whole sheet... I only use strips to protect the chassis. It works well and doesn't cover all the screw holes.
