I would go with that as well, do some reading up on what your adjusting and the result you should expect, racetech has a fair bit of literature on setting sag numbers. Is it that your running out of travel, or is the plate just in the way of the suspension travel?
The plate is in the way of the suspension travel, I'm going to try stiffening it up a little, but if that doesn't work, I'll just buy a proper fender eliminator kit. Thanks for the help
