3 things determine bump stop length:
-Keeping the tire out of the fender/sheet metal
-Preventing the shock from over compressing
-Preventing the spring from going to block height
You're not running high steer so there is no concern with linkage-frame contact.
My reccomendation is to tune your bumpstops to the 2nd and 3rd points, and trim anything out of the way from the body. You should have ample clearance with those fenders.
