I found this in another thread... I believe it's the same spring for the b14 PSS & b16 pss10

I ended up with Swift 60mm springs and thrust sheets, Vorshlag plates and HPA adjustable end links.
Front spring has clearance issue on standard wheel with a 225/40/18 when lower than 333mm eye-brow height. I tried the 'ideal' spring rather than the 'known to improve clearance'.

I bought:
392 lbs/in, 8" length, 60mm ID Swift Spring from HPA
672 lbs/in, 9" length, 60mm ID Swift Spring from HPA

I suggest
392 lbs/in, 7" length, 60mm ID Swift Spring from HPA
672 lbs/in, 9" length, 60mm ID Swift Spring from HPA

For reference, B14 PSS ship with:
400 lbs/in, 8.25" length
630 lbs/in, 9.85" length

Benefits:
Ride quality, response, 'handling', unsprung weight.

What's next?
Watch the clearance, align and get some 1M sway bars.
