Most cost effective way to lower front of S70 by 2 inches while lowering spring rate

[ThaddeusTheBold]

Hi,

I am converting my 1999 S70 to full electric. The front of the car is going to be about 250 lbs. lighter than stock.

I'm going to need to lower it by a couple of inches, and should probably put softer springs on also.

Does anybody know the stock spring rate of the factory springs on an S70 T5?

Can anybody recommend a lowering coilover kit that would be a little softer than that? Or another option?

I suppose I could heat the stock spring until it collapses a bit... but it will be way too stiff, and the stock dampers will be bottoming out too readily.

thanks,

T

Here are some resources for information and maybe custom springs.

Custom springs may not be cheap. Cutting and heating may not be durable.

No heating. You need to be in an control environment or the spring rate will not be equal even if they drop the same amount of height. Just drive it first after the car is complete and roadworthy to see if you like the stock springs.

Yes, I'm going to wait until I''ve driven the finished car before doing anything. Ride height is not critical path right now...

Where is all your weight when finished? In the middle with batteries? The electric motor is way lighter than the CE? Do you retain the stock transmission?
