I have done over 2000 miles on the Michelin Super Sport and to be honest, I don't like them on the RCZ R. The R's harder suspension does not go hand in hand with the harder shoulder of the Michelin tyres. Where the OEM Goodyear Assy 2 provides more damping through the tyre's side walls, the Michelin does not. And below 15°C in wet the Michelin become rock hard with sending a not very assuring feedback to the steering wheel. They still grip somehow but you get a feeling like driving on ice. This relates to higher speed only (above 70mph) so maybe not of any concern in the UK
So the first thing I did was to play with tyre pressure to help reduce this effect, ie make those Michelins "act" softer.
Recommended tyre pressure is 34PSI something, I went as low as 28PSI on the fronts and rear. It helps a bit, but they are still way too hard in their response for R's suspension.
It shows me how precise and well-done the calibration on the R was done by Pug Sport. Excellent! :greetings-wavingblue:
Other than that the PSS is a very good tyre. With them on the car, the R has a more precise steering feedback rendering the opinions about a bit sluggish or feedback-low response of the steering as claimed by e.g. EVO magazine, obsolete. Suddenly the car steers crystal clear and rapid with those PSS on it. Perfect for track days.
The grip is phenomenal. Way higher than on those GY. You need to apply a new level of self-confidence when cornering with the car. Brutal for a frontwheel-driven car. I can tackle well known corners in my neighborhood significantly faster than back on those original GYs.
Rolling resistance seems to be at level with GY as they already been very good.
In wet performance is not as good as on the GY. The GY provide a very high grip level in wet and induce a reassuring feedback back to the steering wheel.
Wear off looks like way better than on GY as I'm not able to measure any wear off after having this distance driven.
For me the consequences are clear, sell the hardly used PSS and swap back to GY Assy 2.
