Looking to choose R-SPEC tyres for my GT3.

Only doing club level track days, not full circuit racing or Targa rallies. Will use my R-specs on a dedicated set of BBS rims, leaving road tires on my standard rims.

Some say the Yokohama A050 is the ultimate and obviously its top dollar. What do people think is the best “bang for your bucks” value option? including from the following:

-Yokohama A050 vs AD08 vs V105
-Dunlop DZ03G
-Hankook z221
-Kumho V70a
-Toyo R888
-Others?

Appreciated and regards to all
