A little bit of inner arch rolling.......
The combination of the Prodrive WR Bilsteins, which have short bumpstops, and the 8x18 ET51 225/35x18 mean't that occasionally the tyre would buzz on the inner arch.
This can be seen below.
The problem is the the inner arch has a 'step/lip' that the wider wheel/tyre combination clip's before contact with bumpstop is made.
It is probably perfectly OK if running the 7.5" Prodrive P-WRC wheel.
With a little help from an arch roller this has been smoothed out.
These images probably best shows the 'step/lip', and where tyre contact has occurred :
Step removed (the bumpiness is where the underseal moved and in some cases come off. A bit more underseal and smoothrite now required):
Images from the other side, which better shows the rolling out of the 'Step/Lip', which 'was' just above the wheel arch lip. Also showing the Arch Roller in action :
