Nice! Would love to go to spa at some point.
Can I ask why you switched from the cup 2’s? I was considering a set for the summer/track days next year.
I found the SC6’s rolled over onto the sidewalls unless you put a lot of pressure in at which point they quickly overheated.
Spa was absolutely amazing, even better than expected. I'd highly recommend it!
Regarding tyres, there were loads of factors that lead me to purchase the SC6's. Main considerations for me were the combination of wet and dry braking/handling, as well as the sidewall stiffness that affects how the car feels.
One of the reasons I went with the Cup 2's was to get a stiff sidewall that didn't take from the overall feel of the car. After removing the Cup 2's recently, I was surprised to feel that they actually had (much) softer sidewalls than the SC6's. Using Michelin's recommended pressures (36F / 33R hot), the Cup 2's rolled over and I ended up scrubbing some of the lettering off the sidewalls at Brands Hatch. I think Michelins generally have quite soft sidewalls - lots of people mention that the PS4S gives the car a 'floaty' feel - they're probably even softer than the Cup 2's.
Using 44F / 38R hot pressures for the SC6's, they didn't roll over onto the sidewalls at all (to my utter surprise). Having seen a friend completely scrub the lettering off the SC6's on his FK2 in one track day, I was expecting them to go the same way. They also didn't overheat at Spa and felt great for the duration of the sessions.
I also wanted tyres that were better in the wet. The SC6s are the best all round tyre in Type R size, quite comfortably beating the Michelin PS4S in both dry and wet handling. See the results
here. On the road, the Cup 2's have less grip than the SC6's, because you can't get enough heat into them. Once warmed up on track, the Cup 2's have more grip but the SC6's aren't far behind.
Lastly, I wanted tyres that protected the rims from potholes a little more, hence the 35 profile. A bonus is that 4x Contis in 245/35/20 size are £650 a set (and come with 7mm tread), compared to Cup 2's in 245/30/20 size being £950 a set (with 6mm tread).
The Cups are surprisingly grippy in the wet, you just need to be careful with them when it's cold
and wet, and also for aquaplaning when they're low on tread. To be honest, I'm just shocked at how good the SC6's felt. My recommendation would be a set of those in 245/35/20 size.
TL;DR: I wanted a tyre with good feel, that was better in the wet and would protect my rims a bit more. Contis in 245/35/20 size, using 44F 38R hot pressures didn't roll over onto the sidewalls at all, didn't overheat and felt great for the duration of my sessions at Spa. This was completely unexpected.
