Obviously I can search for these coilovers, but I can't really find anything that explains the major difference between these 2. I mean, I know that the PSS9 includes 9 position compression/rebound adjustment, but for someone like me who is probably never going to AutoX my car, is the extra $300 really worth it? Wouldn't I be just fine with the regular PSS coilovers? I know that PSS9s get a lot of talk on this forum, but what about the regular PSS? Anyone riding on these? TIA.
