swift springs

BC Racing Coilovers with Swift Springs in excellent condition with around 1000 miles on them. Swift spring upgrade with 8k/10k rates. Comes with spanner wrenches and still have original instructions. I purchased for $1225.00 new. Car is going back to stock, so I'm asking $900 OBO plus shipping...

Hi, I have bought a Umbrella Vrh system front and rear. I have also bought a set of BC coil overs. My question is, what size Swift spring have people been using (ie length 5"), with what spring rates? also what size coil helpers? I have emailed swift springs with no reply as yet (2 weeks ago)...
