so while replacing the front kick up block today, I noticed that I was running a .5 mm spacer. My car was used, and I didn't think to check that... rookie move. Anyway, how will that effect handling compared to no shim?

The shims lower the front roll, its an adjustment akin to taking out washers, but I believe it's more of an adjustment. I run 0.

At WCRC, I run 72/29 with no boost/timing in the ESC, max timing on my motors end-bell. FDR is 6.45, plenty of hit bottom thru top.

I bought one as well.

I still have the JC and PL wings but wanted to give LMR a try. LiveRC reviewed it and they couldn't damage it with everything they tried....well except when they lit it on fire.

Lmr wings do fit but due to the 2.5mm thickness you will need to sand down the shims between mounts and wing.
Some cut a lexan shim to secure the wing properly.

Very durable compare to others wings.

No mounting grid or anything. It fits ok but it's kinda low and short. Super durable tho. I have 2 of them I used for a solid 3 months. Back to the jc for me now though.
Yes unfortunately due to the thickness if the lexan shimming will be a challenge I had to get creative to get a tight fit without wobbles.

has anyone determined if the new adjustable insert suspension hangers are "narrow" or "wide"

or

if the insets actually allow you to change toe and width so the hangers can be either "narrow" or "wide"

I was gonna try using the .5 degree hubs on the opposite sides (putting the right on the left and left on the right) I just don't know how much of a change I'd be making. I tested it out on my table and the shocks are still super smooth and the toe in looks less drastic. Any thoughts?

I run .5s backwards all the time. They make the same amount of difference as running them on the correct side, only the opposite affect
