FYI:
When ordering shims, the center shim packages come with 2 each of .5 mm and 2 each 1 mm, therefore you'd need 2 packages of shims in order to have enough .5 mm shims to lower all 4 suspension blocks the same amount. The Front/Rear packages have enough to do the job.
This was not clear to me until my recent VBC parts order arrived and discovered I lack enough .5 mm shims to set the Car up for tomorrows Race, "Oh Well!"
