<{POST_SNAPBACK}>On the SCX cars you can adjust the magnet pull by adjusting the two screws on the magnet holder under the car.
To get more magnet pull loosen the screws (but not so much that the holder starts to rub on the track).
I hadn't realised that.

<{POST_SNAPBACK}>To get less magnet pull, screw the whole magnet holder with the magnet out of the car, turn the holder 180 degrees and re-assemble. This allows the magnet holder to be adjusted further into the chassis, hence making the magnet effect weaker.
I
had realised that, but thanks for adding it.

<{POST_SNAPBACK}>Does your Scalextric cars have brown or shiny magnets? I suspect you got cars with the old weak brown magnets mounted under the chassis, if so then there are no direct replacement magnets to buy, but you can always hotglue a new type magnet inside the chassis to increase the magnetic pull.
They have the brown magnets.

<{POST_SNAPBACK}>I'm in the process of doing some back-to-back lap timing. I'll post the results later.
I don't know if anyone's remotely interested, but here goes anyway........
First session. 20 laps. All cars run on lane 2 using the same hand controller.
Scalextric F1 cars. Totally standard, with the exception of Scalextric Sport silicon rear tyres.
Williams. Best lap 7.8sec. 7 de-slots
Benetton. Best lap 7.7sec. 4 de-slots
Scalextric Saloons. Totally standard. New Scalextric 11mm grooved rubber tyres.
Megane. Best lap 8.6sec. 11 de-slots
Laguna. Best lap 8.8sec. 8 de-slots
SCX GT3s. Standard. Magnets in highest position.
Porsche. Best lap 8.0sec. 2 de-slots
Morgan. Best lap 8.1sec. 6 de-slots
I then decided to see if I could quieten the saloons in particular and make them run a bit smoother. I don't know if I should have done this, but all 4 Scalextric cars got WD40 in the rear axle bearings and the motor shaft bushes.
Second session. 20 laps. All cars run on lane 2 using the same hand controller.
Scalextric F1 cars.
Williams. Best lap 7.6sec. 4 de-slots
Benetton. Best lap 7.4sec. 2 de-slots
Scalextric Saloons.
Megane. Best lap 8.5sec. 5 de-slots
Laguna. Best lap 8.5sec. 7 de-slots
SCX GT3s.
Porsche. Best lap 7.8sec. 1 de-slot
Morgan. Best lap 8.1sec. 7 de-slots
Third session. 20 laps. All cars run on lane 2 using the same hand controller.
Scalextric Saloons. Now with (badly fitting) Scalectric Sport silicon 8mm wide slicks on rear.
Megane. Best lap 8.3sec. 5 de-slots
Laguna. Best lap 8.1sec. 2 de-slots
SCX GT3s. Magnets now in lowest position.
Porsche. Best lap 7.3sec. 3 de-slots
Morgan. Best lap 7.2sec. 5 de-slots
TBH, I'm not sure what all this means but it's given me something to do while Wor Lass has been at work.
I think I've decided to do nothing more until I've tried the urathene(sp?) tyres on the Megane and Laguna. Depending on the results of that experiment, I'll then decide if I'm going to buy new magnets for all the Scalextric cars or more of Paul's tyres to go on the F1 cars.
