Help With Spring Choice?

[SAFE-T]

We try with our calculator to let the customer tailor the options so that it matches their needs. Very important with the GS to pick the Standard/Sport Touring option instead of Sport Bike even if you have the F model. That said, if you have doubts at all about your rate please shoot us an email and ask

The guys over at vfrdiscussion.com have given Sonic some good reviews as well. If I was going for a straight rate spring I would check them out. For a progressive spring/shock I would look at HyperPro.
