You gotta check out their doors though they have kind of a sucicide gullwing thing going on they are pretty cool and solid. The sales rep at the show said on the most aggressive fastback you had to lower the seats but it looked nice in both version the fastback a tad more so though.
i have the xp4 cage with fixed doors on order but if i really wanted doors and was getting this cage, i would consider SDR doors over the pro amor doors. Very solid doors compared to the pro armor. Tim could tab the cage for pro armor doors if you ask.
