Hey, guys. Can anyone recommend what size Avid pistons to get? I want something for fairly tight indoor and something that will work ok on semi rough outdoor. I'm picking up an XB4 shortly and want to build the shocks right the first time. I thought I read something about running 2 different sizes in the front and back. Also, will the shock fluid that comes with the kit be fine with the Avids are is everyone changing that out? I have a Mugen MBX6 ECO but this is my first 1/10 buggy. I've decided to wait on the new Tekin RSX and then go with a Gen2 Redline 6.5. Good choices? Thanks for any help you can give!
