So first time taking the Golf to this track. In fact its been 3 years since I was last there in my 996 GT3. Totally different driving technique required for this. Great fun though! Only had a couple of hours there but I'm sure with a bit more time a 1:44 or even less possible. Next time!
In this instance I used Michelin Cup 2 tyres 235/35/19 on OEM rims
