Anyone no if a 2.5" center section will fit a 3" without the need to have it modified?
Or does anyone no what the hole center is on a 2.5" system?
A 3" center is 105mm or there about (hole center to center)

TIA

 

You can buy an adapter that reduces 3" to 2.5" like this http://www.ebay.co.uk/itm/GrimmSpeed...item35d25966cf

Is that what you mean?

 

Sort of mate, I have a 3" system on now but would a 2.5" center section fit on the flange is more to the question, without modding or adding

 

Just get a garage ti cut flange and add 3" one, shouldnt cost more than 15quid for it,
