Has anyone found a rear spring with a higher spring rate other than the Hyperpro that Rugged Roads sells? It's supposed to raise the ride height by 20mm. With luggage and a 175 pound rider I need to raise the ride heigth at least 40mm. Honda shows no part number for the spring, only for a spring and shock. Does anyone know the dimensions and rate of the stock spring? For what I am doing I don't need a new rear shock with a custom spring rate. And I would rather have a straight rate spring and not a progressive spring. Leaving for Colorado in the US in 10 days. I'm running out of time for a solution!
