205/45/R16 and 205/40/R17 would be the sizes you're after, they are the closest you can get in 16" and 17" to the original rolling diameter (which is important for keeping the speedo accurate). Fitment-wise you wouldn't want to go larger than 17s, and depending on your offset and suspension you may need to get the guards rolled for 17s (16s are fine). As for the lights, personally I'd leave them standard. The centre garnish on the hatch tends to fade noticeably, so if that has gone yellow then swap it for a non-faded one but apart from that there is basically nothing out there. And in my opinion all the aftermarket lights for the sedan look like *****, so you're not missing out. See my mate has some rims that he's gonna sell me with near new tyres on them so I don't really wanna go paying anymore for tyres that I don't really need. And see we've tried the wheels on the car and they don't scrub any of the guards even under load so there's no trouble with them fitting in, its just the legal side of things. I dont mind paying to get my speedo calibrated to represent the speed properly, if thats the only thing i've gotta do. Im actually looking for somewhere, or someone that I can find out what i've gotta do to get it completely legal, so if a cop pulls me up, i've got proof that it's completely legal. as for the lights, Ive seen a few that im keen on if they come in the right shape n size. Interestingly, the centre garnish you're talking about hasn't faded at all on my car and is in one of the best conditions ive seen. Question tho, is it able to be removed at all? Ive seen some of the later model cars that haven't got the garnish around them and ive been wondering if I can possibly convert mine into those.
