Hi Beeblebrox
275's on the Rear rims is totally the way to go ,i've had mine fitted for about a year now & they have saved the rear rims about 4-5 time so far , Also they look so much wider next to the 255's

With the manual gear selector , I like the action its so positive , I do find going from 6 gear down to 5 gear some times i have to take two goes at it , But its no problem , I find having 3 gates across the selector you have to be more careful or your drop into the wrong gear ( but only if your in a rush ;] ) . On the visibility front ( Rear) if you have a back neck forget it as you need to look around all the time.


Cheers

Andy
