Blowing out as in the struts dont work anymore and not blow out like they explode
I dunno, the struts just go bad really soon. That's what some peole have said and if you call Tein, they'll tell you to just buy new coilovers.
As for the TVS Comp ride...it's gonna be pretty stiff. Even if you turn the dampening to the softest setting, you're still gonna feel every bump 'cuz that's how coilovers are. One way to eliminate this is to get a taller tire. Like when I had my 15" stock wheels, I never felt the bumps, but when I got my 18's, I feel every bump on the road. So if you want a smooth ride, I would go with a 15/16" wheel...maybe a 17", but with a tall side wall.
