Hi all, i need some extended locking wheel bolts to fit my 15mm spacers, to my knowledge the oem ones are m14 x 1.5 and 27mm long, with a radius (rounded) seat, is this right? ive searched the forum but noticed a few people recommending the conicle or tapered type and it got me wondering if my existing bolts are in fact original or not? also by checking other sites they suggest both? so just a double check really, thanks a lot, daz
