While the TLR 22T stadium truck was the second version of the 22 line-up to hit the market, it never seemed to catch on like the original buggy released two years ago - and to me one of the reasons might have been that it's handling was rather quirky and inconsistent which led to an inability for racers to settle on a consistent set-up.
After months of testing and searching and modifications I finally settled on what I call the 22T-R or "Rocket" frontend modification you may have noticed on my April 2013 set-up sheet and I feel it addresses the handling maladies of the truck.

To me, a severe oversteer (or loose) condition was the primary culprit with the 22T, and after spending months chasing set-ups and tire options and various different remedies I all but abandoned the truck because I couldn't really make it competitive on the track. Sure, much of it could be blamed on my lack of talent behind the wheel, but at the same time I figured I wasn't the only one dismayed with the dismal handling of this truck in its factory configuration.

After the 22SCT was released during the Fall of 2012 one of the first things I noticed, contrary to most SCTs on the market, was that TLR did not use the suspension off the ST and instead completely redesigned it - everything from narrower suspension arms to shorter shocks to thicker turnbuckles, all of it was different. And after driving my 22SCT I came to the conclusion that the TLR engineers were onto something, and it also got me to thinking how I could adopt the SCT suspension to the 22T.

The only problem being that the 22SCTs suspension was drastically narrower than the ST, and here's the intrinsic tip of the installation and the 22T-R modification - the use of AE T4.1-style (12mm hex) rims in place of the stock TLR rims. While the 22T rims have very little offset, the additional 15mm of offset (approximately 30mm total) of the AE-style rims conveniently gets the narrower 22SCT suspension out to the standard ST legal width.

In addition, using the addtional offset AE-style rims allows the "Rocket" modification to make use of 4-degree (or 2-degree) trailing steering knuckles from the 22 buggy instead of the stock inline 22T knuckles. As any 22 buggy racer can attest, this not only gets rid of some of the twitchiness by calming down the steering reaction, we've also found it aids in addressing the oversteer problem. Also, use of the shorter and thicker 22SCT turnbuckles should aid in keeping the ballcups from popping off so easily.

The other advantage of using the 22SCT suspension is it also allows for some fine-tuning of track width, as one can use 22 buggy rear hexes to narrow the front width, or any of the 22T alloy hexes (+.75mm or 1.5mm) to widen it.

Finally, I call this a "front end modification" because I've (at least currently) decided to retain the stock ST rear suspension. I've done this for a few reasons. One being I haven't found the need to change (yet); the second being that I don't need additonal steering gained from using a rear sway bar; the third being cost, as I can still use all my stock 22T rims and tires on the rear and only have to buy new rims (and tires) for the front. Could this modification be carried through the rear of the truck? Sure, I just haven't found it necessary.

One final item of mention are the 22SCT shocks, which are shorter than the ones that come stock on the 22T.
As a way to cut costs I've only included the suggested purchase of the shock bodies and shock shafts, as you should be able to recycle your caps, pistons, mounts, and o-rings/seals/spacers.

After doing the 22T-R modification, and a little tuning of swaybar and shock oils, mine finally proved itself to be race-worthy. I could actually run with the fast stadium truck guys and feel the truck was competitive.
No more skittish rear end, and no more twitchy steering. Enjoy!
