TBee,
these are more suited to the R33 and R34.
however, being a 9.5" rim, the +12 offset will certainly bring the wheels out to the edge of the guards, perhaps lipping of the guards will be enough. will double check.
ok, just checked... these were originally on a R34.
i know 10" rims can fit under a R32 with a +22 to +25 offset.
given those specs, these rims are a 9.5" width, taking into consideration that the offsets are bringing the wheels out a further 10-12mm with only 6mm less rim on the outer, these wheels will be sitting approximately 6mm further out than a 10" with a +22ish offset.
slight rolling of the guards may be needed to get these babies to fit.
estimating between $2500 and $2800 landed at this stage.
