Tyres for a BRZ?

[The Notorious S.T.E]

Hey folks, Ste again. I was just looking around getting some new tyres for the ol' girl and I cam across ASDA Tyres? "Lol" was my reaction too, but lo and behold they actually provided me with some recommendations upon entering in my registration: https://www.asdatyres.co.uk/215-45-17?speed=w&load_index=87 

My go-to from this would probably be the continental premium contact 6215/45R17 87Ys. Would anyone advise against this? And yes, I am aware that they're summer tyres, but I'm looking at keeping them for a while so I would rather drive with new summer tyres in the winter instead of getting winter tyres now and being stuck with them in the summer. 

My question to you guys is... has anyone on here used ASDA Tyres before? Or, more specifically, has anyone with a high-end vehicle used ASDA Tyres before? I'm slightly reluctant because it's asda, so I am open to suggestions if there is anywhere better which has better prices. 

Thanks in advance.
