I need some more info, 'Chev Z':
What is the spring rate? As the Zed has near enough to a 1:1 ratio the spring rates will be more or less the same as the wheel rate. Lowered King springs are fairly soft so I'd be looking to go up in rate all round.
What are the tyre temps at after a session: outside, middle & inside of the tire <- this info is important.
As a very broad guess, I I'd say you need more front camber & a possible increase in castor.
The Khumo V70A's are a very soft compound R-spec tyre. Hence they reason they wear quickly.
They are PERFECT for Super Sprints because they have a fast heat up time.
BUT if used with incorrect suspension setup, they WILL degrade very quickly.
Also comparing an road car to a track is just plain silly...
DevilZ, Have you used them yourself? Or are you just going off what you've seen???
The setup of a 4WD Evo is a completely different kettle fish to a Zed...
People, IF YOU DON'T KNOW WHAT YOU ARE TALKING ABOUT - DON'T POST!
I DO NOT want to see in-accurate information posted on this site.
