Where To Get 309 Arches For Motorsport Usage?

[Motor-Mania 0]

Hi there all,

 

i would have posted in "Trackday & Race/Rally Prep" but as a new member i´m not allowed to.

 

I´m working on my 309 XS for regularity rallies. And now i need some more space for my wheels in the rear arches.

 

Does anybody know where to get 309 arches for motorsport usage like in the pic below or any similar items?

They don´t have to be this wide. 10-15 mm more on each side would be enough.

You can gain 10-15mm on 309 arches by folding the lip and 'rolling' them. My brothers 309 has had this treatment in a previous life to accommodate 18x8s and a 60mm+ drop.
