Just got a promo email from Tegiwa. They are selling AD08RS' now
Had this also, I am unsure about them though as it reads as a more economical tyre which makes me wonder if it will be lesser grip on track. Although the tread looks the same I do wonder if it will perform the same and last as well as the older AD08R.

YOKOHAMA announced today the latest addition to its global flagship ADVAN brand. The “ADVAN NEOVA AD08RS", a street sports tyre, will be marketed in Europe only from this spring. The Company plans to gradually make the tire available in 31 sizes, ranging from 185/55R15 82V to 255/30R19 91W.
A re-engineered version of the “ADVAN NEOVA AD08Râ€, the “ADVAN NEOVA AD08RS†has been fine-tuned to meet Europe‘s ECE R117-02 S2WR2 regulation* and raise its environmental performance. While keeping the tread pattern that earned the “ADVAN NEOVA AD08R†a strong reputation for excellent control in dry and wet conditions and superior abrasion resistance, the “ADVAN NEOVA AD08RS†uses a new compound that reduces rolling resistance. The new tyre achieves an excellent handling and low fuel consumption that will fully satisfy driving enthusiasts craving for “speed & funâ€.
* ECE R117-02 is an international standard established in June 2010 by the UNECE (United Nations Economic Commission for Europe) that stipulates technical requirements for tyre noise, rolling resistance and wet grip performance.
