i am doing R&D for ksport for a 510 application, well i finished up what needs to be done to get the kit to work (since the 510 application is similar to the ae86) and i recently decided that I didnt want drift spec coilovers on the 510 as I plan to mainly road race the car. So i am selling a brand new set of full ksport coilovers for AE86. 7/5kgmm with the rear helper spring setup. I only test fit 1 rear and 1 front, $950 pick up, 1000 shipped.
