I have Leda coilovers fitted to my MR2 Turbo Rev3. These were purchased with 7" free length 225lb front springs and 8" free length 325lb rear springs. The ride is rather hard when you have 17" wheels fitted onto them, and after 3 years (under 15000 miles) I want to do something about this as the government is doing nothing to improve our roads.
My question is what spring poundage should I go for to give a more useable ride comfort on the 17" wheels. The standard bilstein suspension for this car has 130lb front and 210lb rear springs. Am I correct in thinking the setup should be a 40/60 % split between the front and rear axles? If so I was thinking 180lb front and 270lb rears with the same free lengths as already fitted. I have the car lowered approx 30mm from standard height and I am concerned that in going for a softer spring and trying to retain the same drop I will bottom out the struts. Any advice most welcome. Thanks.
