Yeah i agree with Suj, a nice factory lookin wide arch, either pre or facelift bumpers, standard spoiler and full interior, nice stance, would suit alot of rims in my opinion (a "euro'd" mk2 golf rallye inspired look id say lol)
Where as if i was going motorsport/rally look etc, id go with the f2 bumpers and spoiler and go with more motorsporty rim, cage, the whole hog lol
As for widening the track, as you said i've got the vr front subframe etc to
help but it its only an inch overall plus or minus abit because of the difference in hub and the way it's mounted (not sure lol) so i think you would need abit more to fill the proper f2 arches, personally dont like spacers lol ive spaced the stub axels off the standard
ibiza rear subframe to make up what the vr front adds, but again i dont think this will fill those arches. Could make the rest up playing around with et of 3 piece splits if your made of money lol or start sectioning and welding subframes/driveshafts together which could cause engine mount problems etc custom ARBs and adjustable top mounts would be needed too probably.
If money was no object and i wanted to build a proper f2 replica, id get a haldex quattro/4motion system from which ever car matched the f2 dimension wise and for the engine, something like a 2.0l tfsi or 1.8 20vt highly tuned or vr6/r32 twin turbo lol proper rally car style
