the mounting tabs on my current rear bar are at the end of the bumper, the mounting tabs on the car it self are 10 odd mm from the end of the wheel arch.
is yours a reshell or a genuine yellow plate evo hypo? a mate of mine has a reshell 3 and his the same as the gsr. my old rear bar lined up properly and has the mounting tabs 10mm away from the gsr bar.
I have a black e3 bar in stock , I haven't checked the plastic lugs , I reckon some of them would be broken , pretty standard for those bars , we just got it in last week .
