I was wondering if Rondell made a 17" version of their 122 alloy wheels
yes they did , good luck tracking a set down and be prepared to pay a lot of money for a set, i agree they look very good on series1's.
fitting is fairly straight forward but as the rondells are 7.5" wide you may need to trim the rear arches, if you get this pro done then it wont cause any probs.
if you are serious about buying one and have some money to spend then join the rsoc and youll get rallye news every 2 months and they have some very very good cars for sale in there, good luck finding one
