I have Strange adj front struts, coil overs with UHT Hyperco springs. 150 lb/in. The car weighs 3150 with me in it. 53% weight on the front. So just under 1,700 lbs on the front end. You can hardly get the front end to bounce with this set up. You have to remember, a coil over set up carries the weight differently than the spring on the lower control arm. So a much lighter spring can be used than what you would expect. Also a lot of it has to do with how long the spring is, and how much you have it compressed to get your desired ride height.
