My mum had them on her old Polo, she sed noise wise they were better than the budget ones shed had on, didnt mention anything about handling, but she aint the sort of person to drive fast enough to determine levels of grip between tyres.
i personally have Uniroyal Rainsports (purley cus they came on the wheels) when you are driving in the wet i havent noticed any difference in grip.
Was racing this Jag around an island earlier 2day, slightly wet roads, he slid the arse end going around (probabily about 40), and only just kept it on the road, i went around int eh same speed and had perfect grip. I realise that the jag was prolly rear wheel drive, and that probabily accounted for the slid.
Btw i have a 1.2 clio, and was keepign up wiht it relativly well on the twisty stuff, only when we got onto a stright bit did he piss all over me.
