You get what you pay for. A lot of enthusiasts do not need the best of everything. Example.. On a 14 second car, a grommet for a weld might be able to be an inch off, but on a 6 second car, that would surely make a difference. Some cars do not need the expensive wires. Be it MSD, Moroso Ultra40, or Firecores. Some cars it would not make much of a difference. But if you are needing every edge, it is money well spent. For what its worth, here is a small list of some users.
It is not counting the new records held in T/F Funnycar, or T/F Dragster.
