I have for sale some Cusco O1 R32 GTR coilovers in mint condition. There are no knocks, or creaks. 2 way height adjustable with pillow ball mounts. Exactly the same as the O2's, just no dampening. Spring rates are 11 and 9.
Awesome handling.
Selling for $1300. No pics yet, still in car. Can be removed at any time.
Not sure about postage... have not inquired yet but can be arranged if needed at cost to buyer otherwise pickup is from Melbourne south eastern suburbs.
