Hi there
I thought it might be a good idea to compile all the spring rates of the springs of the market all in one place, I shall keep this original post updated so people don't need to read all the replies.
So far I have compiled these from reading many threads on this great forum.
Front/Rear
GT: 160 / 668
GT PP: 165/728
BMR Performance: 170/740 (1.2" F / 0.5" R)
BMR Handling: 300/980 (1.2" F / 0.50" R)
BMR Drag: 150/800 (1.2" F / 0.5" R)
Steeda Sport Linear: 198/874 (1" F / 0.95" R)
Steeda Ultralite Linear: 198/874 (1.20" F / 1.05" R)
CJPP: 182-217 / 799 (1.5" F / 1" R)
Eibach Pro Kit: 200-314 / 800-914 (1.1" F / 1.0" R)
Eibach Sportline Kit: 217-331 / 879-994 (1.50" / 1.3" R)
Swift Springs Progressive: 270 / 782 (1.1" F / 1" R)
Linear VS Progressive
For those who don't understand the difference, Linear has a set constant spring rate and progressive is as the name suggest, progressive so as you drive the car harder causing more body roll the springs become firmer to try and control body movement more. Linear are the choice for those who want best handling characteristics with great predictability and less noise, plus linear springs work in harmony more so with the dampers. In short a linear spring will typical be a better handling car. The plus of progressive is when your driving on better roads they maintain better levels of comfort and only firm up on poor road surfaces which can actually mean worse ride quality or when you push the car harder, the downside is your dampers are linear and have a set rate so sometimes dampers can struggle with progressive springs and this is why coilover kits have progressive springs. Another downside of progressive springs is they can be noisy due to coils being much closer together causing squeaks. I enjoy corner carving and a predictable car with as little noise/NVH as possible, so I will always go linear springs.
Anyone knows the rates and drops for other springs or if I made a mistake please post and I shall add them to the OP. Be nice to have them all in one place, maybe an admin/moderator could sticky this?
Spreadsheet with all spring rates in!!
