Difference between Vega SL3 and Vega XM

Hi everyone,

Does somebody know the difference approximately between these 2 tires?
In a track about 1 minute, thx

SL3 less consistent, less grip and similar wear in comparison to the XM3

XM3 cik-fia homologated, SL3 not, just made for north america

Can’t comment on lap time differences, never run SL3
