Hi Guys,
 
Has anyone had any experience or knowledge of these tyres.
 
They are using tyhem as the control tyre for the Sepang 1000km Enduro Races in Malaysia.    http://www.malaysiangp.com.my/news/sepang-circuits-sic-announces-achilles-123-of
 
At around $135 per tyre for 195/50 R15 that's very cheap.  http://www.ebay.com.au/itm/Achilles-123-Semi-Slick-Tyre-195-50-15-Grip-Drift-Street-/220966161671?pt=AU_Car_Parts_Accessories&hash=item33729c0d07
 
Whilst not a true R Spec tyre they may well be suited to the odd track day.
 
Cheers
