I am currently Running on the C-50 compound. it's very compairable to the kumho or toyo's compound. I get very compeditive times on them and they are not super sensitive to camber. I would bet the 214's are faster but for twice the price I'll run the snot out of these. they are not a very light tire, but the sidewall is nice and stiff. they are pretty forgiving at the limit, and have Lightining quick turn in (sharp transision from sidewall to tread)

I would run these every chance I get, however I need to start getting the car tuned for Street tires so sadly this is my last set of the 211's till after MAY
