Does anyone have the H&R Cup Kit installed on their Crossfire? I see many who have installed the Eibach kit, but it makes perfect sense to me to install this Cup Kit due to the spring rate and dampening being perfectly tuned. Here's a link to H&R's website, cheapest I have found the kit is 736, maybe that's why nobody has it. http://www.hrsprings.com/site/index.html
