no manufacturer of aftermarket parts
is going to carry an extended warranty.
Especially when these bits are made for racing/performance.
We all need to be realistic in our expectations.
I will speak with whiteline to asses their warranty limitations and expectations.
as far as camber plates, here is a quote from Wayne @ Whiteline:
I must point out to you that while ever you use the adjustable strut tops that you are currently using, you will be robbed of 20mm of bump travel, due to there design, which will cause problems if you are going for a lowered ride height of "super low" equivalent, taking away the benefits of buying a coil-over set for there shortened shock body.
This is not the case, as the additional travel taken up by the strut tops is above the top of the shock, so it is actually pushing the shock shaft into the body of the shock and that was causing a ride height problem. With changing the top spring platform we are rectifying the ride height problem by lowering the vehicle down over the struts but the shock shaft is still remaining the same distance inside the shock body.
