Default XX4 WE

Just bought a XX4 WE and curious if there are any recommended upgrades while building it up?

Will be racing mod indoors offroad on a fairly bumpy track.

Thanks.

Default shock set up

I run:
57 pistons in front (black) with 30wt and green springs
55 pistons in rear (orange) with 35wt and pink springs (smoother)
yellow springs for (rough)
locations:
front middle on tower, middle on arm
rear outside on tower and inside on arm
just about everywhere.

***switch tires to different track surface***
The stock camber links should put you in the ball park

The only real mod I have done is to shave off the plastis nub on the front carrrier to lower the link. I can then add shims to raise it up if needed. This will give you less camber roll in the corners and seems to work really well.
My xx-4 is dialed and spanks the locals. lazers, xxx4 ya da ya da.
I have been running bowties that I cut to fit front tires and have had really good luck.

Can one of you guys with a fspare front belt do me a favor? I need to find out the length of one of hese to see if the front/side belt from a xx4 will work on the project I am doing, it looks about the same length, but it is hard to tell. A quick reference would be to take the belt and placxe it around your drivers license the short way and flatten it out. If it is approximately 7/8"-1" overhang, it should be correct length, or if you want to flatten it and measure it, that would be great. Also, if you could let me know teh size of the cogs, the ones I need are under 1mm or so.
Thanks, I really appreciate this,
Rod

You just bought one? Brand new? I'm looking for one, any ideas where I can find one?

Two quick mods to help strengthen the front end of the XX4:
First: Install a RC10B2 front brace (AE part #9120) across the front of the front arms, in between the bulkhead and the front bumper. You will have to grind a little on the bulkhead and bumper to fit the brace through, but it really helps prevent breaking and wear on the front bulkhead. See more about it here.
Second mod: Use different casterblock screws up front to connect the arms to the caster blocks. With Losi's normal method, any front impact on a tire (a pipe, landing nose-down, etc) is transferred completely through the back of the A arm, and they break off there with some regularity. These casterblock screws pivot on the arm and screw into the casterblock, splitting these forces between the front and the back of the arm. These things are fairly new; I've been testing them since early August (through the modified nationals) and have not broken an arm since. Info about them here.
