rougeben83 Posted April 21, 2015 Share Posted April 21, 2015 What model year 300zx? 90-95 twin turbo model. The 90-91/92 Had the lighter aluminum calipers, but the later ones had the cast iron calipers. The cast iron version is slightly smaller so fitting under 16" is easier (less to no grinding)- they also don't flex as much as the aluminum version. Either one is fine for an aggressively driven daily IMO. Link to comment Share on other sites More sharing options...
