I'm using a LSr gusset kit. I've only ridden the quad a race and a some practice laps. I've cased a 30ft double and a little bit smaller one that shot me up a little higher and so far no cracks in the frame. We'll see what it looks like after the year is up. The way my year is going, hopefully the whole quad even makes it lol.I'm planning on getting new plastics and my frame powder coated this fall/winter.Ive also thought about a gusset kit just for the heck of it.What kits are the better ones and your guys opinions on them?
