This does bring up a good issue though... A 7" spring is too short. You will always bind the spring before engaging the bump stops. It looks like 8" would be more ideal with 6k rates and you'd possibly need 9" length for higher rates... you'd trade off wheel fitment for stiffer springs which is not worth it in my opinion since you already need more front tire to makes use of even a 6k spring with 200tw class tires.

Also note, a better way to manage roll might be to change ride height to a more ideal roll center. You might be able to reduce roll without needing to stiffen the suspension...
