 But I guess we're waiting for data regarding groove "wear" from the car

I don't know if the grooves are hardened.

I have never warn out a groove, so I don't know how long they last. But the 
carbon seals are very much lighter than the iron seals, and I use too much oil 
in the fuel
( 8 Ozs in 5 gallons of Redline racing 2 cycle) So I have no data on max life 
in racing.
