Peternell Posted August 25, 2001 Share Posted August 25, 2001 I read a buch of the 5-lug posts, but none of them addressed the "el-cheap-O" route. I'm wondering if I can redrill the 82-82 280ZX rear disc's to a 5 on 4.75" pattern? Then I could use one set of tires and wheels at the track for either my Z or my Chevelle. Is there enough material on the rear hub to go to 4.75" spacing? Thanks, Larry Quote Link to comment Share on other sites More sharing options...

Their isn't enough material on the hub flange, you could have them welded up/built up to accomodate the bolt pattern but then you're still left with Z31 4.5" bolt circle hubs up front unless you're putting some domestic front hubs on. I did redrill my rotors if that's all you're asking. I'm sure the wheel pattern fits, but if it'll slip over a larger flange I'm not sure. The Z31 rear rotors should as they have a LOT more ID clearance (11-3/8's OD as well vs. 10" for 280zx stuff). Not too sure what you mean by el cheap o route? We all redrill our rears as it is to get to 5lug. Generally you have ~1/16 or thicker material left at edge of two of the your 'new' holes so no room left for a larger pattern. I had my two 'tight' holes built up with a 'shoulder' as an extra touch. Another alternative to get to 5x4.75" is bolt on wheel adaptors (we generally need an adaptor if we want to run 90's 5 lug wheels whether imports/cobra wheels etc anyhow) that go from 5x4.5" to 5x4.75". These are available from myself in billet 6061 hubcentric spacers with all grade 8 hardware (with an option for wheelcentric as well, ie a protruding wheel matching lip). No pricing online yet but I can quote you if you know the thickness you'd like. Minimum 1" thick for a bolt on spacer generally. Not cheap but then I wouldn't want cheap wheelspacers on my ride. I've seen cheap ones just shatter on imports driving 'normally'. What's the backspacing/offset on your chevelle setup? room for a spacer out back? are you flared at all?
