Hmmmm...i had the same rims on my 4.5 Cam....rubbed like crazzzy in the back...
I abandonded it and get something more universal...enkeis.
You dont get vibration problems?....i found that since our center hub is 60mm, and the acura is 64mm...i actually had vibration at 55-60 mph... The only way to resolve this was to get the venter bore'd out to 73 to fit a ring adaptor. so i sold the rims for profit instead!
and also... since i had the same prob about 3 months ago...do what i did...search for "70mm Toyota Decals" and you should get black stickers with a chrome emblem that PERFECTLY eclipses that Center cap...infact im using them on my Enkeis
Im glad at least one camry owner has the rims i dreamt of having on my car...g/l on them center caps

on that note....some guy has a blue 3.5 sedan with those rims in NYC..... you out there? lol
