Hi, I am new to this forum. I would like to replace the stock springs on my 2008 IS350 with the F-Sports. In some of the descriptions I read they are linear in front and progressive in the rear. Is that the current spring rate set up? The shocks on the car are 2 year old F-Sports. As I understand it will drop the car approx 1 inch.










I am also planning on replacing ft and rear sway bars with the F-Sport bars to take full advantage of the other suspension components. Thanks

F sport Springs barely drops... I don't even think it drop more than a inch go with h&r or tein s tech if u want something noticeable. Or just do coilover and do it right the first time alot of owner upgraded to coilover soon after installed Springs

I really like my f-sport springs. They made the stance look great and they dropped it by about 3/4" on average. I have an awd so I was looking for a safer drop, and it has worked great.

Progressive front and back....I ran them when I first got my lexus. Thought the ride felt better after the f-sport springs
