Stock Spring Rates for is 350?
I want to get a set of springs for my car and was wondering what the stock spring rate is on our cars.
Hopefully i can find something that would match it or if not i would just get some tein-cs and the spring rate same as stock, hopefully it will give me that lexus ride quality.
I just hate the fact that i have to take off the rear trunk lining everytime i want to adjust the rear firmness....
Someone please give me some advice!!!

That's one of the reasons I don't have aftermarket springs and got the OEM sport suspension instead.
OEM non-sport springs are 45 N/mm front and 51N/mm rear FYI
The F-sport springs for comparison (also progressive) range from 40-70 N/mm rear and from 47-66N/mm front.

Why change the springs if you want the same spring rates? Are you trying to lower the car maybe? If so a shorter lowering spring with exact same spring rate as stock might contribute to frequent bottoming, and cause the Lexus-like ride to deteriorate.

The F-Sport brochure for the lowering springs states the following rates for the stock springs on an IS 350:
* Front: 45 N/mm
* Rear: 51 N/mm
* Front: 45 N/mm
* Rear: 51 N/mm
