Archliners, Alloys and so on

[funkyol]

Hi,

(before anyone moans, i've done a search and can't find what i'm after.)

I'm soon going to be upgrading to 16 or 17" alloys on my 2003 VTR.

I've seen everywhere that you have to cut your wheelarch liners away to stop them rubbing - now as far as I know, the arch liners stop all the mud etc from getting to the metal of the inner arch and corroding it etc - if you cut them away, what protects your wheel arches? Or can you do something to compensate?

Second, obviously my VTR is running 14" alloys with 195/55/14 tyres - if I get 17's on there, won't that make the total diameter of my wheel and tyre combination larger - will this then affect my speedo etc?

If someone could let me know, Thanks.
