Keep it old skool.
IMHO, anything older than G reg looks better with small bumpers. For some reason, big bumpers don't look right with F,E,C,B or A reg plates, but somehow D reg looks ok with big bumpers (eg Dizzie's 20VT Mk2).
What colour is it?
Personally, I'd put some nice old skool rims on it, lower about 60mm, keep the small bumpers. Then play with the engine.
