What tyres you got on there nibor?
Those are Dunlop SP Sport 190/625R17 rally slicks, I use them when I go to track days are they have exceptionally good amounts of grip and completely change the cars handling, you cant use full slicks without a roll cage, thats why rally slicks, I now have them on the SS rims and the team dynamics are my road use rims.
And I honestly cant remember where I got them stevey, it was about 10 months ago and I dont remember the website

But I reckon youd get those on, I mean mine are the wrong size from normal too, and they fill the wheelarches a bit more but theres still plenty of space, and also a little bit narrower but handling is still miles better. But they are pricey so its a difficult gamble
