Hey guys,

So I was thinking about upgrading the springs in my Megan LP coilovers to swift springs. I believe I have it figured out which ones to buy but if somebody here has experience with it and could double check it'd be much appreciated.

stock megan LP spring specs

F: 62mm ID; 200mm length; 14 kg/mm
R: 62mm ID; 220mm length; 10 kg/mm

I know from reading on other forums that they say to use the 65mm ID swift springs. But the part that I'm having an issue with is that the spring lengths on swift's site are all in full inches

Soooo, here's my estimation an 8" spring is approx 203.2mm; and a 9" spring is 228.6mm and these are the closest lengths that i could find to the spring.

With these my guess would be for a 14k/10k

F: Swift Z65-203-140 65mm; 8" length; 14kg/mm
R: Swift Z65-228-100 65mm; 9" length; 10kg/mm

If anybody could help with my query, that'd be greatly appreciated.

PS: please don't comment if you're gonna say go buy some other coilover etc, etc. That's not what this is about. I'm looking only for somebody that can actually contribute to my question.

this should help some.

 

It doesn't help at all, I got the parts numbers from swift's site that displays this exact info. I was asking essentially if the 8" would work for the 200mm and 9" for 220mm based on somebodies personal experience with swift springs. Thank you for trying tho
