I’m looking at a set of CRS for my track-days. On 8.5x17 wheels I can get CRS in 235/40 or RE71rs. Also I could get A050 in 225/45. Not sure which would be faster on my ND MX5. 🤔
How is the sidewall stiffness on them? I currently am on the Yoko AD09's, which have pretty stiff sidewalls (which I like), but they are not the grippiest.
I've never had the same size in both. 225/45/15 in a CRS is wider than a 205/50/15 RE71RS as you'd expect. CRS has a more square profile, so you might get a little more width from a 205/50/15 compared to a RE71RS.
They'll be fastest the first and second laps, then get slower throughout the session. The drop off doesn't seem as dramatic as what I've seen from A052 or A050gs. I last drove on A050 mediums back in 2017, they always required a lap or so to get up to pace and then were fast for the whole session. Depends what you're after from a tyre. I do think A050m is the best tyre for smashing lap after lap after lap, especially because they are as fast down to the cords.
@@rhysrhysrhys OK. Thanks. I currently use A050s for sprint days. All I need is 1 quick lap per session. The CRS is a lot cheaper than the A050 in my size, so Im keen to give them a try.
Got a set to try on the i20N soon. Keen to see how much improvement over the rs4 they provide. (Im expecting 2+ secs at smsp)

They feel stiffer than the RE71RS, especially on initial turn in.
How do you differentiate the v1 to v2 ? Tyre suppliers are clueless in NSW about the updated model.
Anything made before 2023 is V1.
Have measured re71rs & crs. Which one more wider?

How do you think they would compare to A050 medium compound on track?
