I was planning on getting some UL coilovers as part of the new group buy however, there is now the option of Swift springs for an extra $290usd. Are these any better to the standard ones that they come with? I am not planning on traking my car but I want the best possible handling, and I have read that UL are the best bet without having a really harsh ride. However, with the Aussie dollar falling is it worth the extra dosh for the Swift springs? Also is the standard 8kg/mm front and 6kg/mm rear the best setup for my application? For those who weren't on the group buy mailing list you can view it here: http://www.twinturbo.net/nissan/300zx/forums/classified/view/169164/POWERTRIX-COILOVERS-GROUP-BUY-2-New-Up-Grades-and-Options.html http://www.300zxclub.com/showthread.php?t=216867
It's mostly a track set up. Swifts are mostly known for their lightweight and for they're consistent rate throughout compression. It'd be nice, but honestly if you're just going to drive the car on the street, it isn't really necessary. It won't make or break the ride quality or performance.
