Just had a set of 4 put on my R and first impressions are that they are good, very good tyres and can see why they are highly rated. I got them from ATS Euromaster £588 all in which although a lot of cash but was far far cheaper than anyone else was offering them as ATS have a very good deal on Michelin tyres at the moment. I was also told I qualify for a free dash cam as well as I bought 4 tyres. Not sure what quality the camera will be. Was going to use F1 tyres but their cheapest was £648.00 which quickly changed to £707 fully fitted. Their promise that they refuse to be beaten on price is a load of rubbish as they never replied to my request for a price match. Anyway the MPS 4Ss are on my car now, performing and looking good.
