TRF501X Low Friction Rod Guide set and Delrin Pistons

[xrider]

So I noticed with the stock pistons there is a considerable amount of play with the piston in the shock body. I have ordered the Hop Up low friction rod guide sets, and delrin low friction pistons. Right now I am running the stock box plastic middle hole pistons with XRay 600 front fluid (roughly 45 weight) and XRay 500 rear fluid (40 weight). My question is when going to the low friction pistons that hopefully seal in the shock body better, will I have to modify my oil weights down since I won't be having the wall sides of the shock body have oil escape there? How much of a oil weight drop should I go to? Also, I have a friend who is using Kyosho RB5 pistons in his Tamiya shocks and he said they fit very nicely in the shock bodies FYI.
