I decided to go with 0.80 springs from RaceTech, Racetech were more expensive than Sonics but SonicSpring's shipping charges to Canada were crazy. At the end RaceTechs turned out to be cheaper delivered.
While I am doing springs and seals I decided to add the emulators as well. Although not cheap people praise them so much I decided to pull the trigger. One rod has been drilled already so there is no way back
.
We will see how this works out when the snow wears off.
