Don't discount the AD08R's for a wet/road tyre. They are a bit softer iirc and I find you can get heat into them when it's very wet. The V103/V105 is more of a road tyre and acts like it, so I'm told anyway.
Yokohama gave me some help when choosing racing tyres for this season (List 1B). In short, now using A048R mediums for dry/wet and AD08R for full wet (i.e. standing water).
If you only drive to and from the track, consider the A048R's. Best semi slick I've used and I've now tried 888's, D03G's and V70's. They grip incredibly well in the wet if you can get heat into them and with the weight of your car that should work.
Assuming it's used slicks at £100 a set, just watch for the number of heat cycles they have been through. A few of the guys who we race with run used slicks find them run down to the canvas after one race (12 mins or so) but at £20/£30 a pop they're happy with that. Get the right compound for the weight/use (i.e. no of laps) of the car or they won't work.
Just my 2p's worth but hope it helps. I've spent so much money/time trying to find the right balance on tyres and what works for one doesn't always work for another. When you get the right tyre for the application though it's nuts how much of a difference it makes.
Thanks m8.
Am thinking V105's as they will be mainly a road tyre, I shall be trying to avoid wet track days in the M3 as M3's no matter how well setup are simply not fast in wet conditions. If I pre-book a day and its wet I will just take the 911 as it excels in such conditions.
The AD08-R's do look great and from having the older AD08's I found getting heat into them is pretty easy unlike other semi-R tyres.
Yeah I was shocked at how the cups went off, they certainly don't like heat, combination of heavy car with very good brakes just seem to melt them. In the morning I was very happy to be seeing 110-115mph at the start of craners on the speedo and think bloody hell gonna be some great lap times when I've got to grips with the braking power. Alas once I had got to grips with the brakes and their ability I was struggling to see beyond 105mph at the start of craners, the tyres had literally fallen of a cliff.
Its not all fault of the tyres though, I had a mind block and was running the tyres 2-3psi above what Michelin recommend and what I ran on the last day and I'd set my rebound slightly stiffer than last time. In short that was a mistake, keep the Michelin at 30psi hot and leave the rebound at what KW suggest.
Still I had a great day and in hindsight was staying out to long, but it was a lot of fun.
On the slicks well luckily my mate get them for his car, same as mine an M3 and he get 3-4 trackdays usage and has no issues with them going off with heat and his car is same as mine but heavier. He is also a good driver and was doing 1:17's around Donnington, he is now super-charging his M3, so will be interesting on how quick it is once done. The slicks he gets of of the Porsche CUP cars fronts, which are Michelin in 240 and 250 sizes, 240 front and 250 rear on the stock M3 18" wheels. Works great for him so hopefully be good for me.
Only thing left on car now is a cage but greatly enjoying the car, gonna be doing a few days at Outlon as well once the cage is in.
