wierdly Ive become attached to these trofeo wheels
http://toronado-trofeo.20megsfree.co.../rollin_16.jpg
But I dont really like any of the standerd wheels that come with the bonne or the riviera (whitch I mite decied over the bonne.. I dont like the whole 4600lb 4door Idea so much anymore)
would the 114.3? bolt pattern be the same.. these are 16'' wheels. but wheel size doesnt matter unless you have bigger roters. (225/60 tires)
so I mite skuff up the oldsmobile letters. not sure though

Linky no worky :(

i would guess that oldsmobile used the 5x115 (same as bonne and riveria)
5x114.3 seems to be chryslers and some nissans (maxima)
and the rwd of course - mustang
