Few different brands and shores, I actually started with some 35 speedmind front and rear, but if anything they were far too grippy, moved to some 40's front and rear (also speedmind), which were not bad, but I chunked the left rear first session out with them, ran them though till the final, where I had taken enough off the fronts that some old 42 Matrix rears were a good size match.

Interesting notes within all that, the 5 ran remarkably well with a badly chunked tyre, and it was also quite driveable with 40/42 in the final, also I ran from quite large sizing at the start and the car handled that well.

But, after playing with what I did, 37/40 is what I'd say would work best, though I had none of that combo to try, plan for me is to get some Caps or Contacts in that shore for future use.

Actually maybe worth noting is the camber I ran, tyres came off the final showing fairly even wear, and I went in running 1.5 Deg fronts, 4 Deg left rear, 3.5 Deg right rear, could have tweaked that a little, like left front maybe 2 Deg, but it depends on how fussy you are with how evenly the tyres are wearing.
