The rear bumper i believe is part of the Mugen lip kit, really like it myself but cant justify the price
As for the wheels, i really like this look but is obviously all show no go and defeats the purpose of a DC5 in my eyes.
If you wanted to achieve that look with a JDM DC5 then i think the same wheels with an offset of et45 would give a similar effect.
RSX - standard offset = 38 iirc and et20 wheel would give 18mm further out each side than standard
DC5 - standard offset = 60 and et45 wheel would give 15mm further out each side than standard
(et42 would make it the same but don't think you'll find that in those wheels)
Also taking into account it is a 9.5j wheel that adds a further 1.25" to each side of a standard wheel (7j) which is 31.75mm. So in total the outer lip would be 46.75mm further out :shock:
A lot of effort and arch rolling and maybe pulling ?
(all of this is what i think so don't take it as gospel and go and buy wheels based on what i've said)
