Cusco has had a bit of a rough time this year with their official US office (Nukabe) closing a few months back. During that time, the only seemingly reliable way to get Cusco was to go direct to Japan. Thankfully, Cusco has a new US office and is back in operation.
They're a bit hesitant in stocking the 370z parts as there haven't been many orders lately, though Cusco parts are always sought after for almost every Japanese car, so it's surprising that the 370z has been slow for them. Here is what they have for the 370z currently:
Front Sway Bar
Rear Sway Bar
Standard Spec Coilovers
Pillow Upper Spec Coilovers
Type-RS LSD
Type-MZ LSD
The sways will be in stock in about 3-4 weeks. They won't be stocking the coilovers yet until they see more demand, so they're currently special order with a 6-8 week leadtime.
Let me know if you guys have questions about any of Cusco's parts.
