Nitto Invo 230/45 R17 Subaru sti Type RA 20 miles March 23, 2018
Fitted these tyres after using RE002 and wouldn't rate them highly, wet grip is average and dry grip is better but not amazing. paid the same price for these tyres compared to RE002 and would say that i should of gone with something else .I use these tyres for wet track work and spirited driving but dont trust them enough to push them in a good rain.

wear rate on these tyres is low but have seemed to last a fair amount of time so cant complain about that. if you were looking at these tyres you would want to get them on a decent special to justify the tyre.

Wet grip more impress than dry grip, heavy tire noise after 50% wear. Overall good but not the best budget sport tyre.
