xrad - thanks - no, they aren't currently covered - my car never sees dirt, and i am under there after every drive cleaning things up - but while i have never heard of anybody having this issue on anything but an off-road car, yes, contaminants can get in there if you aren't careful - a good washing periodically takes care of that though
firefish - i am also not a fan of delrin on this car - i had used it for decades, but on this car it just doesn't seem to work that well anywhere but the swaybars, and even then you have to do some things to make them work well - there is a thread here showing a mod for that
poly is tricky stuff - they are noisy unless you get ones with grease fittings and grooves
i currently have delrin on the front, and poly on the rear
as for what else to do to make these work, spring rates and controlling them are key - you need pretty stiff springs to take advantage of these - at least 300 up front and a wheel rate of 300 in the rear - anything less with these bars, and the car just slides around - i have no idea what the cayman has, so i'd check that out on your setup - also, you need tires big enough to provide the grip to prevent the car from feeling like it's on marbles - the stock sizes won't do it
the lower brace will be essential to this all working too - the camber change that happens without it will most certainly make things a mess
the good news is that once it's all done, you can dramatically reduce the negative camber in your setup - i am very happy with the way it feels
it's all about a complete package with balance though, so it gets pricey to get there, and most people will never see the benefits in their driving
