The Height of Bride Zeta XL is 880mm, the Stradia XL is 860mm, the height of the Recaro SPG XL is 860mm which its the height that you need since the holes are too low. Since the Zeta IV(
looks horrible to me) is coming out Bride is discontinuing basically all the Gen 3 seats DEC.1.. You should be able to get a killer deal soon... hope that helps
