no modification to the koyosho boots 1 bit. the rear shocks are a bit snug.. thats why i showed both a front and a rear. but they do fit without stretching and tearing. they're good fit for both front and rear.. a dead ringer to me, rather than the f/r thin losi boots.
and every other run.. thats crazy. im by far a pro, and can actually "feel" the difference, so im just happy my boots aren't torn jacking up my shock pins, and getting my oil all mucky.
anyways, just thought ide share the info.
