That's the best thing about SF (and webfora in general) the ability, with all due respect, to post opposing opinions
Due to their relative "heavy" chassis, the sprung guide on the RevoSlot cars is one that actually works as intended.
And in working as intended I mean that the spring pushes the guide down on the rails, instead of as with most (plastic) "lighter" slot cars, pushing the chassis up.
The sprung guide is also the reason why RevoSlot cars can be run on various Track/braid surfaces without the need to change the guide ride height set up.
Reason for me to retain the stock set-up for all of the
RevoSlot Endurance Series "hand out" cars.
As for the lateral play of the guide, as can be seen here in the image below (
Posted by Gerrit/ePilot) the Revoslot guide holder is a two part design which in combination with the tall stem on the guide and the guide screw keeps the guide secured and straight through out the whole of the guide suspension travel.
So if you want to save yourself a lot of (set-up) work...I would revert to the original Sprung Guide set-up.
With kind regards
