i've got r32 calipers now and found out they sit further away than the s14 calipers, so in theory i could use gtr 295mm discs with a 11.5 mm spacer like doski has used, only for some reason r32 discs are extortionate price at £150 each

, i'd like to use bigger discs but i could live with 295mm instead of 274mm std ones, i'am not going to be trackin the car only straight lining, so they should be adequate until next year, then i will probably do what you have done mart.cheers for the help.
