.

Now it's time to share my favorite top 10 option parts for my amazing XRAY XB2 carpet edition. Check it out.

326180 Stainless Steel Battery Weight 50g

It’s awesome to see how a so thin metallic parts can change a car a lot. This option increases the stability on big jumps and make the car faster on bumpy tracks.

323110-G/323120-G & 322110-G Comp. Susp. Arm rear L/R & front

Make the car more precise to drive. My favorite option part.

323351 Alu Rear Upright

This option part gives you more adjustability for wheelbase and makes the car more stable with more steering.

323041 Alu Rear Roll-Center Holder

This parts will be necessary when using more than 3mm shims underneath the ball stud to keep the strength of the car.

365471-K Alu Drive Shaft Safety Collar - Black

This part replaces the original plastic part and you never need to worry about a drive pin coming loose.

322312 Brass Front Lower Arm Mount 26°

It adds extra weight to the front of the car to give it more steering.

329701 XB2 Body Light Weight

Taking away extra weight makes the car react quicker.

322041 Alu Front Roll-Center Holder

Another useful part that makes the car more precise to drive.
