The Dremel trick for the front tyres is one of the things I suggested in the opening post.

I’m not sure I agree that truing the back tyres is only half the job on a Scalextric, Carrera, Fly etc car running on plastic track - although sorting out the front certainly helps, especially if the guide is being lifted at all. The guide needs to be deep in the slot. Re-profiling the braids is also important to get the guide nice and deep - something that’s in the SlotRacer’s manual here: https://slotracer.online/manual/basics.php

I have to say that using the Dremel on the opposite wheel is a bit of a palaver. Much easier to either…

• Grind the original tyres on the rig by putting them on the back wheels
  
• Find a pair of smaller diameter tyres from another Scalextric, Carrera, Fly etc car
  
• Use a pair of NSR or Slot.it front tyres if wheels are standard Euro size.
  

My aim with Scalextric, Carrera, Fly etc cars on plastic track is to get the front of the car resting on the guide - the front tyres no more than a couple of millimetres off the surface to act as stabilisers, ideally coated with varnish to reduce the grip.

I’ve used all three options and they certainly help with handling and lap times on a Scalextric, Carrera, Fly etc cars on plastic track. Indeed, I mentioned this briefly in the opening post - and I hope it’s a useful tip for those exploring tuning Scalextric, Carrera, Fly etc slot cars for the first time.
