Is it possible to have too much grip?
I ask because I have issues with a few cars tipping over rather than oversteering.
I have tried sanding/rounding the edges of the tyres, additional weight at the front, moving rear wheels out slightly (when possible) to increase overall rear axle width (which helps quite a bit). All are on Scalextric tyres and I run them all at 12v but still have some saloons that prefer to tip rather than slide. It is a particular issue with my "classic" BSCC/BTCC cars.
This was not such a common issue on Scalextric track but since I changed to Policar it has become a problem.
Is there anything else, not involving major chassis surgery, that could help?

Alternatively, is the Policar car track providing too much grip?
As heretical as it may be, can anyone suggest a method of reducing the grip provided by the track?

As the cars you mention are probably mostly quite narrow I suggest you investigate adding weight low and as central as possible to the chassis.
This of course  means opening the car up and adding weight(material of your choice) to the chassis where possible that doesn't interfere with the interiors or other parts.

Also when refixing the body and chassis dont crank the body screws up really tightly....allow a little movement between the two parts.

Most 'Classic' touring cars are narrow with a high centre of gravity so, yes, they are very prone to tipping over. Munter's suggestions are the way to go to tame them down.

The only time I see too much grip is on a tight twisty Rally stage and the cars struggle to slide the rear end round hairpin bends, especially if there's something in the middle of the bend that the rear of the car gets stuck against. 

On the main club track I can never have too much grip, high grip = fast lap times.

If the car is rolling over due to the high grip I keep adding ballast between the motor and front axle until the car stops rolling over.

Hello JaguarXJ220, assuming you are running without magnets,...are both front tyres touching the track??, ....narrow track cars with a high(ish) cg. are very prone to "tipping" out of the slot, if the front tyres do not touch , and , require the front tyres to act as stabilizing outriggers to alleviate this. Widening the rear track will help, but, without the front tyres touching the problem will still exist (even after adding significant amounts of weight) .

This is easy enough to rectify, by, either using some thinner braid, or if that does not solve the issue, but using some taller front tyres.

A more involved procedure would be to 1/ use a guide with a thinner profile, or 2/ modify the guide tongue to allow the guide to recess a bit further into the chassis plate................try the thinner braid/taller tyres first  .

If in fact your front tyres do touch the track, widening both front and rear track as much as your rules allow, using a softer braid, and using weight on the outside edges (perimeter) of the chassis will help,.....ensuring some body movement/float will also help.

You can also remove as much weight from the body shell as possible (lexan interior), but this may not be in accordance with your rules or how you like your cars to look.

Yes 
it's possible to have too much grip 
But
That doesn't normally result in the car tipping over.
Understeer (car just fails to make the corner) is the symptom of too much grip.

You are not suffering from too much grip, just "car setup" woes

Chris's suggestions above are all worth pursuing. 

Also:
Get the chassis down to 1mm off the track. High ground clearance can trigger roll-deslots
Ensure your front axle has minimal vertical movement.
