I am running a 986 Porsche Boxster 3.2S in CSCC Modern Classics. The car has 18 inch wheels fitted with 265's on the rear and 235's on the front. The dampers are Gaz adjustable. The weight is 1200kg.

Tyres can be List 1A/1B/1C.

For dry use I am running Too R888R's and finding them to be good. For wets I am using a new set of Pirelli P Zero's and they are awful.

Any recommendations for better tyres, especially the wets?

Thanks

Thank you for that advice. They do have very good reviews and are available in my sizes. An interesting thread on them also elsewhere on PH.

Do you have specific experience of them? I see Uniroyal make a Rain Sport 3 and a Rain Expert 3. Do you know the difference?

Thank you.

I think I may have answered my own question. The Rain Sport 3 is the sportier of the two tyres.

Thank you to everyone for the helpful comments. I have three sets of wheels. I think I might ditch the old Michelins and try the Nankang AR-1's which I can then try back to back with my existing R888R's. I think I will ditch my Pirelli P Zero's on the wet set of rims and try the Uniroyal Rain Sport 3's which seem to have good reviews when it is streaming wet.

Any more comments will be welcome. I will place my order in a weeks time ready for Oulton Park and Spa in June.

Thumbs and Richair. Now you've gone and done it! I thought I had a plan and now I am not so sure. AR-1 still looks good for the dry (or the Dunlops) but you are casting doubt on the Uniroyals for the wet.

Does it follow necessarily that a List 1B tyre will be a softer compound than List 1A?

Your advice is greatly appreciated. Thank you

I should have added a note for Richair that we will be racing together at Spa because the Modern Classics and Future Classics are combined. Look forward to meeting up. We are the grey Boxster (No 8). I am racing with my son.

Well here's some feedback. We raced at Oulton Park on Saturday. 2 qualifying sessions and 2 races. Everything from damp but drying, soaking wet and bone dry!

We ran Michelin Cups in Q1. It was damp but drying.

The Uniroyal Rainsport 3's were amazing in the wet. My son, in his first year of racing, was running P3 and P4 overall 12 minutes into Q2. Our final qualifying position in Q2 was P7.

In Race 1 it was a wet start but looked like it would dry. This was a good call so we didn't run the Uniroyals. We went out on the Cups and following a start line red flag incident it was drying quickly by the time of the restart.

I couldn't buy any Nankang in our sizes, so we ended up using unused (but a couple of years old) Michelin Cups. In the dry (Race 2) they were excellent. Better than the R888R's but they did go off towards the end of a hot 40 minute race. I also ran out of talent and spun!

We played around with damper settings and tyre pressures and are working towards a good set up in both wet and dry. A good day. Best result was a 2nd in Class in Race 2.

Thanks for all the input. It was really helpful.
