I use these to get rid of the flex.

XRAY X1 CARBON FIBER FRONT ARM WITH SUPPORT 2.5mm

I use thosr on my carpet X1, they are much stiffer and more stable on high grip than stock arms. Had to open up the hole slightly, was causing my pivot balls to bind.

I still prefer the stock arms on lower grip asphalt though.

Can someone confirm if the 2016 body is the same as the 2018 body?

According to the parts list, it is (#379701).

Anyway guys, I plan to race my X1'18 on indoor carpet only (being in Europe, it's probably not going to be the black CRC carpet anywhere) and I was thinking about the Fenix Gear Diff... is it worth it? (Oh, we still race 21.5T in F1 over here, and the car will run on the alu flex chassis.) I would appreciate some thoughts on this.

I have found it to be worth about .2 a lap. Instant acceleration out of corners is the biggest benefit.

That is what I am using on the front of mine. Running on black carpet

Are they very effective on crc black carpet to avoid traction roll?
I use volante tires on this carpet and i have some problem with traction roll, even i have alu chassis...

Arms won't prevent rolling. Smoother driving; and gluing front tire sidewall would be more beneficial. Also front tire prep(sauce). Loose grip open track 1/2-3/4 sauce from inside to middle. High bite tight track; no more than the inside half for sauce.

Absolutley glue the front tires to prevent traction roll on black carpet. Also softer springs in front and side

A new tricky part from Fenix Racing.

Want to shave some grams from you Xray X1?
Want to make it lighter where it matter the most?
How about to reduce the unsprung weight of your car...

How about taking half of the weight off from the X1 Front Wheel Axle?
How about getting a better and faster spring response
How about adding the Titanium cool factor?





For those of you located in USA, CRC is getting them as we write.

I want the Fenix kingpin (the one with the ball on top)...I wish CRC would get those in.

Thanks. Seems to be a good choice on carpet then.

Still waiting for that promised second video from Fenix, though, showing how to grease/oil it correctly.

I've run hudy on the new black carpet without traction rolling issues. When i went to CRC tires i was forced to glue

I had to glue the side walls they still bit in too hard on high grip black crc

Well after perfecting the front floating link design, I decided to see what I could do with the rear. I give you the first that ive seen, floating rear links. I have a final product mocked up on a stock xray rear end and the clearances are awesome, Current its sitting with a 96 spur and a 36 pinion with tons of room to go bigger yet, the axle is also spaced to 188mm width. Chassis width drops from 115 to 97mm overall. This has increased the cars responsiveness as well as high speed cornering and transitions. Kit will be available soon in either cf or aluminum though cf seems to be the best in testing. For anyone going to the WCICS race in Victoria on jan 5-7th I will have this car and the mockup rear end there racing.
