would you pick that or go with another setup. I've done some searching and i've been reading the spring rates are pretty soft leading me to think the ride quality and response will not be a great improvement. How does this compare to lets say... tein flex and basics?

 

cusco ir primarily valved for track driving and even the street setups are very stiff... depends on your preference but they'll def be more stiffer and ride a little more harsher than teins.

 

they have it all over the Basic's and the Flex in terms of overall handling and response. They are stiffer than either though, and the valving is fairly aggressive.

 

softer rear springs for the cusco coilovers will cause oversteer? Im planning to combine the cusco coilovers and the cusco sways.

 

my car was very neutral with the Cusco's in it and Cusco sways -

 

are the cusco rebuildable? how is the support in US?

 

Cusco does not rebuild dampers..they sell moderately priced replacements instead and we usually have a couple pieces in stock.

In the 5 years we have sold Cusco now, I have only had to have a single damper replaced (and this goes for ANY car!)

 

Was checking Zero1 with pillowball mounts, and it's not cheap. I was expecting for a non-adjustable shock to be around 1000$, but at 1500$, it's only 200$ cheaper than HKS RS and a few other quality coilovers. Is it really worth that much?

 

never used them on a Z so cannot comment
