First batch will be red. Next batch will have black as well. I have many parts coming in the pipeline so the Kyosho red parts will look nice and will compliment the color of the parts on the car now- even the brown shock caps/collars (why brown?)

Thank you guys for coming through for us. I alluded this to you guys when the car was released.

Can't wait until mine gets here, sorry for the guys that spent a little more yesterday, though those did look good..

The gold rears seem to be 2.50 lb/in (measured 2.14). So any of those close to it on the chart. The Losi Reds would probably be the easiest to acquire.

My experience is that the others will fit in a pinch but they just don't feel the same as X-Gear!

I couldn't agree more. The feel is very different between the TLR spring and the X-Gear. If you needed a specific spring in a pinch...yea the TLR springs are cheap. But you def get whatcha pay for.

TLR springs will feel a bit more progressive. Also, TLR buggy and truck/SCT springs of the same rate will not feel the same.

from my personal dealings with kyosho/losi springs and what i've heard from others... Kyosho gold is close to yellow.. Kyosho red is in between a losi yellow and a losi pink.. but closer to a pink.. if that helps.

Softening up the springs in the rear will not help a push.. it will make it worse. If you are getting a push with the RB6, you either have a glaring setup issue, or are having a tire/insert issue.
