I have a pair (read: two springs) of 9kg swift springs. Swift part number Z60-203-090. These are 8 inches in length/height and have a 60mm inner diameter. These will fit most all after market coil-over setups. Most aftermarket coilovers come with 8kg rear springs, these would be a great upgrade for someone.

Selling because I switched to a different mid-link setup and had to go with 65mm inner diameter springs. These have around 7.5k miles on them, and are pretty much in great shape. Price is firm but includes shipping to the lower 48 and paypal fees.

It should be noted that you should be aware of the valving on your coilovers before upgrading springs, however most quality coilover companies valve their shocks with about 4kg leeway (read: can typically run +/- 2kg springs then what they are valved for) so there should be no issue with running these.

If you have to ask what stiffer springs will do for your car/driving then this might not be for you, but a HIGHLY simplified version is it will give you some more oversteer if used in the back of the car. I do not recommend using these to replace front springs as it will lower the spring rate with most coilovers.

Glws perfect for a bc upgrade.
Wish they were 9in as my swift 8in keeps my rear a bit low for me.
