Hi everyone, I was wondering if there are any stiffer and harder springs available for the rear shocks. a customer wants us to convert his 456GTA and put the shocks from the 550 to eliminate the hydraulic system. My concern is this car has an automatic gearbox which I believe to be alot heavier than the Manual car. so the original 550 shocks setup will not take the extra load from the gearbox. Any help on where or who makes harder springs for the 550 would be much appreciated.
Some threads on this. Conclusion is to redo hydro system is much cheaper And less hassle than a custom fix. BTW the 456 is a heavy car.
