Hey gents,
disregard this post if it's already common knowledge, but I stumbled on this site that does the wide Rallye style arches for the 205, they appear to be the cheapest price I've seen for them as well..
Possibly good for someone looking just to modify a base model without cutting the arches for GTi trim?

Hopefully helps someone out?
