Thanks for the input guys really useful, I'm keen on rolling my gaurds just seems like too much hassle when its something more for looks then anything else even though the RS is still at standard ride height.
My car isn't making big HP, should be over 100bhp at the flywheel. So that isn't a real issue when it comes to needing the surface area for grip.
I did my order today, its going to cost me $1700 for a complete set of Performance Wheels Superlites 15x6 with tyres including spare, wheel nuts and center caps through my local City Discount Tyres
