NO!!! Don't do it, they are the most common wheels ever seen on a Cinq, even when I was modding my Cinq 4 years ago everybody had them wheels! How much do they cost? about £600?
I had Fox Racing 5 wheels 6.5 x 15" 195/45/15 tyres, PCD was 4x98 and offset was 45 with 3mm spacers on the rear. They were fitted by Halfords/Ripspeed in Altrincham. They caught on the anti roll bar on full lock and slightly on the rear arches with someone in the back. Suspension was Eibach springs -30mm. Cost of wheels £450!
If you want a motosport look get in touch with compomotive direct, they can literally custom make your wheels. I nearly bought a set of 6 x 16" wheels with low profiles but ended up selling the car! Cost about £600
Also you cound get any 16" wheels on your car without any major arch work as long as they are less than 6.5" wide. Fox Premier 2 (6 spoke) wheels are perfect, same PCD and Offset as above. Cost about £500
Have a look around, you can get more for less!
