I think the KE70 is actually an old school shape, probably the very last of the old school corollas. After the KE70, corolla styling goes headlong into 80's styling. In my opinion, new school rims are are at home on new school cars... I really hate to see new school rims with low profile tyres on old cars, its just not right. Some smaller, possibly even 15 inch old school rims on the KE70 would look tough as nails
Watanabes look good on at least one KE70 I've seen on this site
As for hotwires, I have them on my KE70 and I honestly think it looks perfect for the style of the car... remove the side strips from the car and chuck some hotwires on with dish and you'll have one tough looking KE70
