Re using this guide with the FLY & FLYSlot chassis:  we have seen significant variability in the size of the guide post holes on FLY and on FLYSlot chassis, even from one chassis to another for the same model car.  On some of the FLY/  FLYSlot chassis the guide post hole is a very snug fit around the shaft of this guide.  Now our preference is to have a guide that cannot wobble so we here at 1/32Slotcar will use a small round file and carefully, oh so gradually, enlarge the guide post hole to fit the guide.  Be aware that there is some risk in using a file to  enlarge the guide post hole, very little plastic needs to be removed and removing too much plastic will make the chassis unusable.
