Just to update anybody interested in these tyres.......
I got them fitted today by the boys at Nottingham 4 wheel car allignment (great peeps and top service

)
the tyres look very aggressive with a mean tread pattern and they hold the road like super glue.
If any of you guys happen to have this month's max power mag, then there's a track/road test between the marangoni, dunlop SP, Toyo T1 and Yoko (can't remember which), etc and these bad boys beat them all.
when it decide's to rain a little i'll go see if they're worth their money
i'll get a pic posted at some point.
