LE charges 500 for labor plus 110 springs, 30 seals, 30 oil, plus tax if you're in CA. Other shops are in the same ball park.
I never got the 919 shock done, since Jim didn't call me back about it. I guess he didn't need to mess with the 919, he does mostly race stuff.
Just look for a good local suspension shop.
If you decide to go with RaceTech, they charge $165 for labor plus parts: compression damping kit, rebound damping kit, springs, seals and oil. About the same as LE.
Some shops like using Ohlins cartridge kits. Add a couple hundred if you go that route.
