I have Bridgestone Turanza ER300 on my +8 which I find pretty good, but suspect theres better out there. The best wet handling tyres I have experience were Dunlop Sp Sport on a 944 Turbo, but they may have changed since then.
Goodyear do EfficientGrip model that is A rated for wet and although I have not tried myself other Goodyear tyres I had on other cars have been good.
Be very interested in what tyres other +8 owners are using.
