I've always seen the tremendous weight-reduction factor for FG leafs, that one is obvious, but FG just seems like an unlikely material for a spring. Do these things not break? Thats a LOT ov stress, and even more on a race car in corners. Are these safe? Sure, some here have track cars that never see real streets, but how about for a street car? or do you people drive these things (and abuse these things) on the street as well...???
i bought the hypercoils leafs but not until i did some research on them and asked around on forums before buying them - their are guys using these springs on street. dirt. roadcoarse. and scca racing with great success - punishing them in the corners and never having one crack or break. They are pricey but i do like the fact i can pick my own spring rates... I would love to save a massive chunk o' weight, but i'm leery. I'd also be leery about ordering them, as if they're not quite the rate, or height, load, whatever you wanted, there is no adjustment. How do you make SURE you order the right one...???
