2008 VW Touran and 18" wheels.....

[Manni78]

Hi all, i have recently brought a 2008 VW Touran as the wife said it was time to get something "sensible" to ferry the kids in and for her childminding work.
We have had the touran for a couple of months now and i actually quite like it but would like to upgrade the wheels as its a bit boaty on the 16"s and fancy some 18"s to fill the arches a little more.
I have seen a couple of sets of Volkswagen Scirocco 18inch Interlagos alloys which are 8x18" ET44 with 235/40 18 tyres BUT WILL THEY FIT??
Any help or advice about upgrading to 18" wheels on the touran would be appreciated!!

Thanks, Rob

Wow 27 views but no one can help me! The bloke selling had the wheels fitted to his mk6 golf.

According to this calculator 1010TIRES.COM - Wheel Offset Calculator (http://www.1010tires.com/Tools/Wheel-Offset-Calculator#Results) you will have 13mm less inner clearance and the wheels will project a further 25mm to the outside.
