mine is what you call a widetrack converted NON sport.
Sport clios are considerably wider, in terms of track, than normal ones: they use longer front wishbones, different hubs to house bigger discs and calipers, and obviously different dampers. The front subframe is also different with an extra gearbox mount. the rear axle has a thicker torsion bar as well, and disc brakes.
this means that if you want to fit sport suspension on a non sport you'd be limited to just rear axle and springs, because the front driveshafts would be too short once all the other components are fitted.
65 and 80hp diesels, however, share the same gearbox design as the sports, this means that sport driveshafts fit straight on (driver side has to be a Cup one) and so does the sport subframe with the extra gearbox mount.
i haven't got the cup setup, would be a waste on my car !
Mine is also a tad wider at the back thanks to some 10mm spacers, and it's also lowered on eibach springs.
It's all on my project thread, i followed what others had done before, a fellow forum member (GrahamS) describes the whole process in detail on his youtube channel, TrackIt.
