Kevin K... I am converting my shocks to the losi shaft with the asociated pistons and I have a couple of questions. For my foam car I am using Rob Love's setup with #2 pistons and 80 weight oil. What piston and oil are you using for rubber on carpet? I also measured the kit pistons and the associated and I found the stock pistons to run about .005 bigger than the associated... is this going to be a problem?
