Hey guys,
Im about to pick up a used set of KW V3 coilovers for my 9. Spring rates are front- 9Kg, rear- 6Kg with helper springs.
I want to swap the rears for 10 or 11Kg.
Question- What size are rear KW springs??
I did some research but didnt find a definitive answer. Some say 60mm, some 65mm.
Are they 6,7 or 8 inches tall? And any recommendations on the brand- Swift, Eibach?

Thanks

 

I know that they're 60mm, but not sure on the length. I run 6" long springs w/ the helper springs on mine.

 

^Thanks for your reply. I PM'd you

 

Length should take you about a minute to figure out if you have a measuring take and a jack.

One thing to look at though, if you want to go lower than you are and are already at the bottom of adjustment go with a shorter spring cause the stiffer spring at the same perch setting will sit the car higher.

 

I am looking into Swift 10Kg/mm 60mm 6" springs right now. These are stiffer and shorter than others so I can address the issue you have pointed out. Thanks

Anyone knows if 10Kg would work good on stock KW rears? Someone mentioned that 11Kg is close to the limit of the shock.

 

I ended up ordering a 9kg Swift 60mm 6" springs for the rears. Spoke to KW, they said that would come close to the stock valving limit.
