they are pretty much road legal track tyres the slicket you can get i really wouldnt suggest rain driving with them.I've always had yoko's and never had a problem. Although has anyone had these? I'm thinking of getting a set with my new alloys. I use my car all year round and I'm worried about grip in wet weather conditions. More specifically they will be this set up at the bottom.
as for yoko vs falken yokos al the way ive had uyokos on my last car prada spec 2 they were amazing tyres.
on the mini i have two yokos on the front a539s and im happy with them so i will replace them all to that in the future
