Putting the washer under the o-ring is now moving the force/energy that is being absorbed by the chassis to the shock and the shock tower.
The only final I actually completed was the last one, and in that I had a broken front bulkhead (top two screw mounts) and the front driveshaft was busted so I removed it, and ran 2wd. (and was 5-6 seconds a lap off the pace)

Will have a look at your latest set up anyway, thanks.

I haven't tried that yet, but I have dropped down to the 1.1 bars all round.

Are sway bars for this car bad because the base clay setup sys 1.2 away bars front and rear I'm on a smaller clay track should I remove them? And does anyone make premounted that fit the xb4 yet or are there some hexes I can put to where I can buy premounts for the car? Here's a picture of the track I'm running on so will this setup work I've already been told I should probably run 5 and three in the diffs but I followed the test of this setup sheet pretty exact and haven't had a chance to run the car yet should I change anything? http://www.teamxray.com/xb4/download...sheet_clay.pdf thanks for the help guys I'm also running the diggity shock towers so I have an extra outer mounting hold on the rear tower help is greatly appreciated I also put 30 and 27.5 in the shocks thanks again

The swaybars aren't bad, they're just not suitable for my track. I run outdoors loose dirt/clay and needed to stop it sliding around -> fastest way to do it is to pull the swaybars off. It's probably fairly telling if I say that we need to run ifmar pins or flipouts (or sometimes ifmar studs). In contrast, I would probably put the swaybars back on if I was running, say, barcodes/rebars/whatever and come close to tractionrolling...

I've found on our tight technical track no front sway bar and a 1.1 rear work well. Results may vary for others.

I take it back... the car isn't a TANK when going up against a Steel Beam at full speed!!!

Tweaked my aluminium chassis, broke my composite chassis, destroyed my saddle pack.... But I get a newish car with a cool story to tell

Did the topdeck hold?

Is the new aluminium chassis flat lying on its own on a glass board? Because my new one isn't...
On the other hand the aluminium chassis is so soft on its own that it'll probably get straightened out when attached to the plastic chassis.

BTW: Picked up my XB4'14 yesterday, carbon parts are sealed now and I'll start the build this weekend

Regards,
David

everything held. I thought for sure an arm was going to be severed off but to my surprise it didn't.... I just destroyed everything else! lol

the old aluminium chassis was bent and tweaked from side to side. the new aluminium chassis didn't lay down perfectly flat but wasn't tweaked.

I'm still waiting for my 2014 to arrive*

The chassis is quite soft, my v1.0 was bending at the rear after ten packs, just the tiniest bit but still disconcerting. The chassis wears badly at the rear as well. A harder/stiffer chassis would be nice not only for tuning options but to increase the durability.

Bad driving on my end, it caught air and a mystery beam magically appeared.

I got the car used, its about months old, time to update but I might keep the 2013 for my son to race with. Absolutely love the car

In short, a rear bumper will be nice, like what is on the K1.

Really not needed......nothing wrong with the original chassis as it wears very well (unless you're constantly chassis slapping)

Tuning chassis flex is done with the flex screws and longer top deck or additional rear chassis brace

If you're concerned about excessive chassis wear due to a very rough track you could always opt for the Bugle Boy front bumper and chassis undertray

XB4 2WD pics and tech. So it is probably a 2WD version, for NOT low traction;
