I havent put too many miles on since the swap, but my initial impressions are good.
I think that for the amount of drop the Swifts offer combined with an even stance for the wagon (they are wagon specific) they are good springs. I just dont think they were matched with the correct strut (stock KYB). If I had them with Bilsteins they would probably be an excellent choice for someone who wanted the drop they offer with a good ride and handling.
The Eibachs on the other hand were apparently made and tested with the stock struts and match pretty well with the stocker KYB's. I will eventually do the Koni inserts because I believe it would be an even better match with the Eibachs. I dont race my car on a track, or am into auto-x like some are on this forum. My wagon is my DD and I want as near to perfect combo of sportiness/comfort as possible. From the little time ive had the Eibachs on, they feel good...not a whole lot different from the Swifts but there is a noticeable positive difference. One example: speed bumps. I no longer have to almost creep over speed bumps, I can actually feel the suspension absorb the speed bump more since the swap instead of previous. Im happy I found a set and think I will probably be happy with these for some time.
