A mate's 20vt with g60 fronts and 8v rears (did have drums) with no pressure reg can lock the rears when stamping on brakes. Yeah I must say the t1r's can take some g and provide good grip when cornering in the wet, its just you can't make snap actions or chuck it into corners, but you can drive smoothly and hard and still stay tight. When it rained on my 1st track day on them I thought sod it theres loads of run off if needs be, and no kerbs, and although running wider than in the dry, it hardly slid, and I never span the car all day. So far the best tyres I've used...
