I have a 3-pt Scroth Rallye3 with some custom anti-sub straps (makes me a 5-pointer).
For the rear points, I simply used the rear frame rail bolts. Just remove the rear bolts, slide the harness brackets underneath
the rail (lining up with the hole of course), and put the bolts back in. I also put a washer in the other rear bolts to keep the surface level. I didn't want to tighten them down and bend the rail. Takes about 3-5 minutes to install/remove. 10mm ratchet and phillips screwdriver is all you need.
Rear point is the center lap belt point. Pull the rear sear (bottom cushion) out of the way, use a #55 'star' wrench and unbolt
the bolt. Slip in the rear bracket and put back together.
The sub straps are triple-wrapped around the 1/2" bar underneath the seat. (part of the seat frame). Helps keep the lap belt from riding up when you tighten up the shoulder harness.
Clear as mud?
It's worked GREAT at the spring zing AX, especially with the OEM belt also used. No need to brace for corners. It was my first time using them. First time at a Solo II ax actually.
