GL Racing GLR

The GLR is known to perform quite well in stock form, not needing a ton of upgrades to start. In addition to the brass chassis, the other two upgrades are these metal side damper pistons and 1 degree camber knuckles. Let's see what they do and how to install them. They are pretty straightforward.
The default camber in the front is 0 degree. In practice it's a bit negative because of slop in the axles. Adding some negative camber can help the outside wheel gain more traction during turns.
Remove the knuckles from the king pins by disassembling the top suspension arms. As usual, I'm supervised during my RC projects. This one is no exception. Servicing the GLR front suspension is pretty easy. It's so similar to MR-03 too. Annoyingly, GL omits the axle pieces from the upgraded knuckles. Remove the old ones from the plastic knuckles carefully. Because the ball stud is going into aluminum, it's important to apply some loctite. These GL axles are designed without threads near the bottom so that they really wedge tight into the knuckles.
There's now some extra bling and weight up front. The negative 1 degree camber should help address GLR's understeering tendency.
Next, we will replace the side damper pistons. On the GLR, the springs on the side dampers center the motor pod. More importantly, the pistons and shock bodies, with some grease, dampen the motion of the roll action. Dampening calms down the car during turns, keeping the tires on the road as much as possible. GL's metal pistons fit the shock bodies more snugly. This means more consistent dampening compared to the stock plastic pistons. Loctite is needed when reassembling the ball studs.
For these side dampers, the internet recommended Kyosho 15000 grease. This grease is useful in many other places. I'm not sure what's the correct amount of grease to use, so I'm just going to pack the shock body full.
With everything back together, let's see how it feels. There's more dampening than I have anticipated. It feels more consistent than the stock pistons with thick grease. This should work well on a high traction surface like RCP.
This is Sammy and thanks for watching!

Plastic pistons, I feel even 30k isnt enough damping. Mostly in that once the grease is displaced, the effect diminishes. With the tighter tolerance on the metal piston, the grease does a better job at holding both surfaces at the same time. 15k has a similar effect to a newly packed plastic 30k setup, but lasts longer.
The other important factor to note, is that the spring perch position changes on the metal piston due to the use of a threaded ball cup rather than integrated like the plastic. This means that the threaded shock collars will need to be adjusted for similar preload levels when changing the pistons.

Thank you EMU. When I first put the 15k grease in, I was impressed by the dampening effect. Should be awesome on a high grip track. Your point on the threaded ball cups is also good; I didn't think about using it as a way to balance the pod.
