Let's see if you're still saying the same thing after you have experienced the Cup 2s .

Why not just have goodyear eagle F1's on the CSL rims, buy a set of 18's and run the dunlop 03G.

You can do nice long 25min stints, insane grip, predictable and will keep most drivers on slicks honest.

Billy, wash your mouth out - I think you mean MPSS or their successors .

Dunlops or Pirellis. Not even worth comparing to Cup2.

I am going to compare the cup 1 with the cup 2 tyre in a track that I have over 1400 laps with car (~1000 with the CSL) and 150 with bike.
The only option for me to go faster in this track is if I cut through the grass and skip parts of the track This is how fast I drive the CSL there.
I have the consistency too; I can drive lap after lap within 200ms.

Going in this track with the cup 2s is what I am going to do and I will compare the corner speeds between the 2 tyres.
I hope this makes sense.

Excellent - that would be perfect

However, might I suggest that instead of cup 1 vs cup 2 comparison, if possible we do a cup 2 vs any other modern R tyre (e.g. AD08R, R888R, TrofeoR). That way its between choices we would actually be making.

My guesstimate is that the cup 2 will be quicker on the clock than people are giving it credit for. Granted that consistency/staying on point could be an issue on the relatively heavy M3/CSL as reported by others here. Plus its about all round wet/dry use where the older cup 1 (for example) was not as good with standing water.

Ultimately it does also depend on style/objective of the driver's track outing. I do interrogate my video logger after track events and hence do keep a sharp eye on my driving performance (notwithstanding I'm not a pro)/the car's performance/the tyres at every event. The real world indicator being the lap time.
Hence for me the pace over a decent 30 min stint (in the afternoon when temps/pressures have all settled down) is key.
For others who may not be into the data side of things but enjoy dicing with friends/just driving as fast as possible, they may rate a tyre differently based on things like operating window/longer stint performance etc without perhaps an eye on the lap time.

Anyway, looking forward to what Alex may find against the clock.

In the meantime, I may be choosing between AD08R and Cup 2 for my CSL rims. Both have performed remarkably well on other platforms for me (AD08R/XBow and Cup 2/911s) but I've not tried on the M3. On the M3 I've only tried the R888R which were great on track but too noisy/rumbly for the road. Welcome any thoughts.

I tell you what goodyear Eagle F1's are bloody brilliant tyre, so much wet grip.

Im goodyears all day long.

I would just buy the dunlop 03G, if they handle my aggressive driving style and 25min stints at snett with approx 1360 kg M3 + full tank of fuel and two up you lot will be flying.

All I have ran is the old Dunlop 02g, loads of cup1's, slicks and dunlop 03G's.

Shim you not got any old 18 inch dunlops you can bang on for SPA?
