Well I rebuilt all the shocks on both cars. Clear x-rings. Bushings looked fine. I noticed quite a difference in how the shafts slide in the seals. Much more free than they were.
My rear springs are still close to the bottom of the adjustment on both cars to maintain 24mm ride height.
Where is everyone elses adjusters? Every pic I've seen has the adjusters close to the middle.

Here is the overseas order info.

If you google them you can go to a translated version or Chrome will translate automatically.

For one item like that I would just email them and they will send you a paypal total.

[email protected]

They will send you an EMS tracking number as soon as it ships.

On my latest order I paid Friday, it shipped Saturday, and I will have it tomorrow!

I have attached a couple pics of how a one item email/tracking works.

I also came from a B5M to the RB6 and the smoothness of the shocks and the way the car handles is what sold me.

I've built several different brands of cars recently, including TLR, XRay, Durango, Hot Bodies, and the Kyosho shocks are a step above all these. They seem to weep less, and build up with less air due to the upside down fill design. RB6 is a well refined car.

Mine are orphans like a few here, when given some love they just go. I do love to build kits so each of mine went through a "frame-off" resto.

You are so right about the shocks, the last set of o-rings just went in with Kyosho oil and after 20 shock jobs I can only agree. Very well refined indeed

Anybody try this chassis on the RB6 to get the pack in sideways? This car looks like an RB6 twin..

Guys, i am really looking for some help.
Just started racing 2WD this year and am really struggling on our home track.
Track is loose- medium grip most times. Quite a few big jumps and pretty rough.

Started out with Joe Pillars loose track set up ( Found here: http://2wdmod.com/2014/06/09/rb6-loo...for-mid-motor/ ) mid-motor and not really liking it that much. Buggy is like driving on ice anytime i am off throttle, rear end consistantly washes out randomly and is near impossible to drive.

- 2x1.6 pistons F/R
- 27.5wt Losi rear oil, 30wt Losi rear oil
- 3 Rib Pro-line fronts and M3 Blockades rear
- 7.5 Turn motor, was running 21 tooth pinion. Going to try 23 or 24 with less punch off the get go.

I am totally new to this 2WD thing. I drive 1/8 with confidence but am ultimately embarrassed to run this at the track. All other 1/10 class drivers run Associated.

Please looking for some advice.
