Making its debut today at the 2017 ROAR Nationals, is an all new prototype body for the TLR 22-4 2.0. Unofficially dubbed the "Low Profile 22-4 Body", TLR used the fan favorite styling of the 22 4.0 body as the basis for this new body shell that will fit the 22-4 1.0 and 2.0 4wd buggies. With a lower cab section, and no vertically fin, the style is matched by a more flowing and better rotating body when compared to the cab forward offering.
JP Richards was the first to don the body in practice and had this to say, "First glance, the body has that new sleek and edgy design. Then you hit the track and it really helps the car have a fluent feel, with a good balance of steering, stability, and traction without the overbearing feel of a tall front cab."
The Low Profile Body is still in the prototype stage, but is roughly scheduled for a late 2017 release. Check TLRacing.com this fall/winter for further details.

Last Wednesday night, I made the trip to Beachline Raceway in Cocoa, Florida and I ran some tests on turf, while Frank Root did some carpet racing in California. The team has found a steering rack modification for higher spindle heights on your 22 4.0 or 22 3.0 vehicles that will help fix the bump out setting. Currently, if you run spindles with 4mm (or more) on top, the only available Ackermann setting with acceptable bump steer is the #2 Ackermann arm. By flipping the bell cranks upside down, and mounting the rack on top of the bell cranks, you can now achieve the correct bump setting when run the #1 and #3 Ackermann arms, or the 22 2.0 spindles which Frank found to be really good with his testing (TLR234007). This raises the inter-steering link to compensate giving you the right bump steer when running 4mm on top for spindle height.
With the rack flippers, some Dremel work is necessary to the steering rack arms and front bulkhead for clearance. Please reference the pictures below for details.

This week we will do a product spotlight on TLR’s new Stiffezel front wheels for the 22 line of buggies. I asked TLR’s Frank Root for his opinion on the Stiffezel front wheels and here’s what he had to say: FR Using the same design as the standard TLR wheels, the Stiffezel front wheels have been molded from stiffer composite, which allows the wheel to flex less under higher load. During testing, the team has found these wheels to create more consistent at high speed, while adding more steering in longer, high load turns. The best analogy used by a tester was, "The Stiffezel front wheels make it feel like I tightened a servo saver, even though the 22's don't have one." These wheels are highly recommended, especially for use on higher grip clay, carpet, or astroturf tracks.

This week I would like to cover the next question that came up on my recent post on the #22empire and that’s 1/10th scale gear diff maintenance and rebuilding. In the picture below, I’m rebuilding my gear diff and I’ll give a description for some key items when rebuilding a gear diff. A) Disassemble and clean all parts thoroughly with motor spray (do not clean o-rings with motor spray). B & C) Show all parts after cleaning. D) Reapply new high-pressure black grease and the O-rings followed by the flat washer on both sides of the diff. E) Reapply threadlock to the outdrive setscrew. F) Refill your gear diff with your diff fluid of choice. G) Tighten the four outer case screws in a cross pattern. This will give you a nice new freshly rebuilt gear diff ready for racing.

This week I would like to cover the next question that came up on my recent post on the #22empire and that’s 1/10th scale diff maintenance and rebuilding. In the picture below I’m rebuilding my diff for this weekend’s Hot Rod Shootout race at Hot Rod Hobbies and I’ll give a description for some key items when rebuilding a diff. This diff has about three large race events and some club racing events on it and you can feel it’s a little gritty. Picture A1 and A2 shows “flipping” the drive rings and trust washer for a new surface area; this is key because not doing this will result in having the same gritty feel you're trying to get rid of in the first place. Picture B shows cleaning of the internal parts of the diff (I.E. outdrives, rings, trust and diff balls). Picture C shows reassembly of the diff with new silicone grease. Picture D shows reassembly of the trust washer assembly with new high-pressure black grease. This will give you a fresh new diff ready for racing.
