I sense a jab at me, lol. Stop making sense and let your "feeling" dictate your actions, lol.

So. Still trying to lighten my buggy.

Lunsford buckles: 3g lighter.
Lunsford balls: ~6g lighter.

buggy without wing, shell and wheels = 1301 (500f 801r)

I estimate wheels/tyres to be approx 210g. Body/wing probably about 50g.

Might find a different battery strap in a + shape (as opposed to Y) so I can remove half of the battery tiedown posts.

Maybe I can get a lighter battery...

Anyone run it with the side pods cut down? I normally use only 1 screw in the front and sometimes no stiffening screws at all. Also have no use for the receiver tray. When I get my stock buggy I am going to try to run the diggity cf holders and run a lengthwise velcro to secure the battery. Also maybe run without the spur cover and eliminate slipper thats around 10 grams I think.

I showed this shim to two other people at my track and they were both unaware it was even there.
I think thats yours, I looked at my brand new motor guard and there is no shim attached to it. Its possible you put one on there, or one was there without you knowing it.

Is that the AE part? And does the kyo slipper bolt up?

Huh. Forgot about the slipper. I've been running the avid and from memory it's fairly heavy...

I've been considering chopping the sideguards too. I run without stiffening screws.

Yeah but the Losi is like 3 bucks. If I can get it to hold in place there's no need for the $13 Kyosho I guess I'll ram some 3M tape between it and the bumper. Cheers,

The manual definitely tells you to put a .5 shim in between the motor guard and the hinge pin brace.

No to use the TLR spur the parts are

http://www.rcshox.com/tlr22-garodisc/ or 2 of http://www.amainhobbies.com/product_...r-Friction-Pad
and
http://www.amainhobbies.com/product_...-Spur-Gear-70T
or for a quieter tranny I run
http://www.amainhobbies.com/product_...-Spur-Gear-76T
Kyosho plates, spring retainers bolt right on. Just a drop of CA to hold the pad onto the spur till you tighten it. Get a very consistent feel with the garodiscs.

haha yeah I don't mind the 3 $ part or the permanent 43$ one. Only concern is the weight of the ghea part. For 17.5 no go for sure.
Also with the new updated kyosho brace, I just hammer it flat and its good to go for a few more weeks.
Got a lot more life out of it until I upgraded to the ghea hangers .

I had no idea how light a machined TC spur could be until I got my first car a month ago .

Yeah it's pretty strange that nobody else seems to have this. It's actually pretty nice because the shim is held on by the tab so there's no fumbling around with the spacer while screwing down the rear hangar. I only noticed it because it fell off one day while i was trying out the 521 arms.
