Anti-squat and rear shock location 22 4.0

Hello everyone,

This past weekend, I attended race #2 of the TLR Cup at the awesome facility RCE. I did a lot of running/testing both indoor and outdoor and I took notes from running my TLR 22 4.0, and I would like to share the most significant find. I changed anti-squat quite a bit and I ended up running less than normal. I started with 2 deg which is normal for most setups and I went to 1 deg to try to add a little more side grip in corners along with more forward grip. The change did this, but maybe a little too much than what I was looking for. I finished with 1.5 deg and the rear shocks laid in on the stock tower to have the balance I was looking for. So, if you’re in the situation looking for a little more rear grip with added side grip try these two set-up changes.

8IGHT 12 deg front spindle carrier set

Hello everyone,

This week we will do a product spotlight on TLR’s new front spindle carrier set, 12 deg for TLR’s 8/8E/8T 4.0 vehicles (TLR344004). Let’s review the differences between more and less front caster. Less front caster has less initial steering when entering corners, but it should have more mid-corner steering with less corner exit steering. More front caster has more initial steering when entering corners, but should have less mid corner steering with more corner exit steering. I feel the 12 deg spindle carrier helps the car in higher grip situations by not upsetting the car on corner entry and exit. It also gives the ability to steer on power in the middle of the corner. This front spindle carrier also comes with the optional roll center hole, which is an added tuning item that can work with the inter front camber link for optional front roll centers.

Stiffezel TLR 22 4.0 arms

 Hello everyone, 

This week we will talk about TLR’s new material called stiffezel. The TLR 22 4.0 comes with stiffezel front and rear arms (TLR334046 front, TLR334047 rear). A nice tuning option is the standard material that is slightly softer then the stiffezel arms (TLR234046 front, TLR234079 rear). I experienced this option at round one of the TLR cup in Omaha switching from stiffezel rear arms only to the standard material rear arms and I found a slight increase of rear grip and stability on the tricky and bumpy surface at the HobbyPlex. I haven’t tested the difference in performance of the front arm material, but I asked TLR’s Frank Root for his opinion and here’s what he had to say: FR “It’s not really a balance change, the car feels like it gains the stability of a heavier car with the stiffezel front arms, without losing the nimbleness of a lighter car.”

22-4 2.0 flattening

Hello everyone,

This week we’re back from the first TLR cup at HobbyPlex in Omaha, Nebraska, which was a total success and a great event. I can’t wait for the next one coming up quickly May 19-21 at RC Excitement in Fitchburg, Mass. At this past weekend’s race, we (me and teammate Hunter Holmberg) helped teammate and race one winner, Tanner Denney, with figuring out the tweak on his TLR 22-4 2.0. Here recently we’ve found adding a .5mm shim between the rear stock tower and above the right rear anti-squat blocks helps get the car to lay flat (see pic one). After adding this shim flip on your 22-4 2.0 take it over on a flat surface and make sure all four points of both front and rear shock towers lay flat (see pic two). This might require the bottom two front screws for the rear shock tower to not be tightened fully to make this possible.

Front toe-out

Hello everyone,

This week I would like to talk about front toe-out. For most of my racing, over the many years, there has really only been one way to run the front toe on any vehicle and that’s at 0 degrees, or no toe-in or out. Things have changed recently with many drivers going with a good amount of toe-out on the 1/8th scale side and the 1/10th Carpet/Turf of their programs. I find that I use it more in 1/8th scale, as it helps in sweeping corners (I think this is because the outside front tire on cornering just doesn’t steer as much with full steering). However, this can get a little dicey at low speed turn in as it will initiate the corner quicker; to compensate with this, I find that I usually run one spring stiffer than normal.

22 4.0 Rear Wing Angle

Hello Racers!

We have an all new screw-in type rear wing mount on the 22 4.0, and I wanted to share a little detail about how the adjustable wing angle works.  It is very similar to the 22 3.0, but mostly just with a slight change of the angle options.

The mounting pads on the wing stay are designed with 2 degrees of rake from the start, so if you mount the wing without the wedged shim, your wing will have 2 degrees of rake.  You'll simply add the mounting washer above the wing and you're all set.  The kit does include a shim that is wedged by 4 degs with markings on both sides, 4 deg on one side and 0 deg on the other.  If you run the fat side of the wedge forward directly on top of the mounting pad of the wing stay, you'll effectively have 0 degrees of rake with your wing.  If you reverse the shim, and run the fat end to the rear, you'll have 4 degree of rake on the wing.  Regardless of which setting you're running (0,2,4), you will still run the mounting washer on top.

0 degree - Fat edge of wedge shim forward, shim under the wing
2 degree - No shim used
4 degree - Fat edge of wedge shim rearward, shim under the wing

More wing angle will increase rear grip throughout all turns, but especially at high speed.  It will also increase drag (reduce straight line speeds), which may affect spec racers a little, although not likely too much.  I have been personally running 2 degrees myself in most cases on my 2wd buggies, and 0 usually on 4wd as a good starting point.

Have fun building your 4.0s!
