I would be careful running track tyres on the front and normal tyres on the back, on a hot day the back end can get very loose. Not much chance of that at this time of the year though !

With respect to tyres, there's two ways to approach a trackday....

1) Fit cheap road tyres (even part worns) and go out with the intention of wearing them out and the expectation that the car will be a little wayward and a bit of a mobile chicane round the twisty bits - end result, lots of laughs and (relatively) minor expense

2) save up, fit proper trackday tyres and exploit the considerable increase in grip and have some decent dices with machinery that should leave the Coupe for dead. End result, lots of laughs, some raised eyebrows and a higher expenditure.

Generally, I'd go for #2 because I'm very competitive. However, what I wouldn't do it mix and match - as has been said above, the rear end of a Coupe gets very wayward when the tyres get hot, which they will do very quickly if you have trackday rubber up front. Putting the sticky rubber on the rear is pointless, as the front will just push wide as soon as the power is on - might as well stick with Option 1 rather than waste good trackdays tyres on the rear.

FWIW, this was the state of my 100-mile old Toyos after just ONE lap of Bruntingthorpe

Again at 2 mins in.

I believe the technical term is 'doing a barnacle'.

I believe i was on road tyres at the time at 205/55/16.
Entered the corner pretty bad aswell but got lucky and never hit the wall the left hand side.
