The very few and far between Powertrix coilover review -- picture heavy

roy'sz

So by stock springs you are talking about the original powertrix or are you referencing the ones that cam on the coilovers originally? Also as far as longevity is it those compared to the swift? Just trying to get some info that way if I do pull the trigger on these I have some education on a good direction to go.

Yeah, I was not clear on this one. I meant comparing swifts with the springs that came with the powertrix coilovers. Longevity - depends on what you'll be doing. If DD with occassional autoX, you'll be fine with the springs that came with it. The swifts are probably overkill for DD but is great to have when you need it. There is a difference in materials used but will not translate to an immediately noticeable difference on the ride. Perhaps over time it will. These set just brings great value with or without the swift upgrade.

So what you are saying is that the swift springs are stiffer than the powertrix coils? Is it that you wanted a stiffer spring? Just wrapping my head around the whole situation. From it sounds like is that the swifts have a stiffer range of ajustablility than the stock powertrix springs?

The spring rates between the original front powertrix coils and the swifts are the same at 12k. The difference is in the build and material used. Long term, the swifts will be more consistent, sag/bind less, retain it's shape, etc. compared to the stock powertrix coils (look at the two springs and compare). For those who care about weight, the swifts are lighter. For the rears, the powertrix coils are at 10k. The swifts rear will come it at 10.5 or 11k. I may or may not feel the slight difference once installed, I do not know and will have to see when it is installed in November. I am not clear about what you meant regarding your last question.
