Picked up a Renntech kit a month ago. Like you, had questions on the actual adjustment of the coils. Not too much info out there. Called Renntech and spoke to John. He is the man. Very knowledgable and goes the extra mile to make sure you get what you need. If you get the answer it would be nice to see the post.

It's an awesome kit. I chose it over the KW kit because it is suppose to have the ability to go lower. Weird thing is my rear suspension is not doing that. My installer was surprised and told me KW sits lower. I know that isn't true, but what can I do. Little frustrating because I don't have a installer here in socal that is a Renntech expert.

it's literally a 40-50% more compliant ride now. i finally don't hate the ride quality of this car on bad roads. beautifully engineered. i literally noticed the difference as soon as i puiled out of the shop in 20 feet. stunned.

if you're wanting comfort over performance (although the performance is dramatically increased too), i'd go renntech. the resolution is my installer is useless and i should have done it myself and saved 1200 bux. i always do my own suspension work but got lazy. lesson learned. he forgot to put the set screws in the adjustable collars. that is the set screw that you obvioulsy loosen to adjust the height. if the wheel is removed and that weight isn't pulling the aseembly down, the spring won't turn as it's uder too much load. it's a ***** to have to access it from behind the wheel, but the only way.
