View Full Version : PN LCG Motor Mount body height problem

I was given a PN LCG v1 motor mount, and have a problem with body ride height. I only have the '1' axle ride height adjusters, and have them oriented right side up. I know that Part # MR2294A is a replacement set of the ride height adjuster, but I don't think adding back that 0.45mm is going to make enough of a difference.

Should I just move the body mount? If so, any recommendations?

These picture were taken with a very stiff h-plate and no batteries installed.

With '1' upright:

With '1' upside down:

With '1' upright, and front body clip lowered 2.5mm, which then causes the body clip to scrape:

If you don't have different axle guides you could either reposition the side clips or shim your T-Plate attached to the chassis (not the motor mount0. I've had this problem and until i got some different guides I used a broken T-plate end to shim the chassis and raise the ride height.

Good idea bout using a broken T-Plate to raise the chassis/body.. I'm leaning toward moving the side clips. Even if I had the '2' axle guides I can only raise it another 0.5mm. I guess that might be the difference, as the rear bumper is about 1.0mm up and the side skirt is 1.5mm

I guess I need to clearance the rear more?

The Enzo body sits pretty low... I usually grind away a bit of the back. On new unpainted bodies, I test fit the body with the clips double sided taped in before I glue them. This way I can see how much clearance there is. I usually mount the side clips a little lower than an autoscale, so I can raise the body slightly. This allows you to more easily lower the chassis with the diff height adjustment spacers.

I would just shave a little more of the body, as long as your wheels dont rub the body, and the body doesnt rub the track... you should be fine.

I can easily remove more of the body, but it is hard to get back on. :)

I took the side clips out of the body, and am going to move them down about 1.25mm. The difference between my hard and soft H-plate on body clearance is huge, at least 1.0mm in droop difference. I want to set it up so I can try the soft, but not make the hard run any higher than necessary..

After searching around, it seems that the droop on the Kyosho FRP plates is big enough that a top shock is required. That is why I'm seeing such a big difference between ride height of the extra hard SSG T and medium FRP plate.

Regardless, I'm going to raise the body a little bit.
