Paint code, go here: http://colorwebtech.ixell.com/index.php?index〈=en Type in "647" and scroll down to Renault and you will find "Gris Titan" in a number of varieties. GRIS TITAN 647 is the code for the 182 in Titanium Silver. The place you get the paint will be able to help you from there which one to use.
182 Cup is tricky because of the larger, stronger hubs have 60mm bolt spacing on the strut to hub as opposed to the 54 mm on all the other Clio II sports. If you just want a road car, I Koni Yellows would be the obvious choice, but you can't get them for 60mm
You can go B14's or H&R coilovers; but these are quite expensive now. I think a fresh set of top mounts, fresh set of front dampers (these are cheap from the dealer), bushes and ball joints and you'll have a sweet little road car. I can't see myself recommending lowering the car for the sake of it; Eibach pro-lines if you must. Geometry goes to whack when you dump the Clio II's (I learnt the hard way) and you're better off with the travel and suppleness on the back roads.
The quiet KTEC exhaust sounds nice and subtle on the 182 as well. The 98 RON RS-Tuner map makes a big difference to the mid-range. I would say that the peak power figure is probably no different, but it pulls in 3rd gear 60km/h - 110 km/h much better. Car also starts and performs much much better when cold. Whiteline rear sway bar on the stiffest setting is not "snap oversteer" at all, it puts the car into a nice neutral balance in the dry. In the wet it can be a little bit oversteery; only proper slide I had was on a racetrack with a big lift. A very very nice mod that makes the car feel totally different and super playful. I have a set of genuine roof bars on the 172, they come with some weird pentagon shaped key from memory. Quaife LSD not worth the cost for a road car. ITB's a big hassle to get properly tuned or use the KTEC GEN90... Not cheap either. You lose cruise control and ESP as well, which is not worth it for me on a road car.
KTEC make an intake that is a hose and pod filter and it isn't cheap. They suggest that it makes power on the stock box, but the change is not significant. You can create the same thing yourself, but the standard airbox and a good filter is going to perform just as well. Have to record the sound for a listen to tell if it is normal or not.
