Is it possible that you can use extended wheel studs, rather than using the press in studs?
We fabricate several wheel spacers for S13s (240sx). They have the same lug pattern, 4X114.3mm. Once, we did go a bit crazy on wheel spacers. Made a 50 mm spacer plate that made a 40+ offset wheel stick out 1.5" out of a S13 body fender.
