im pretty sure posting a few paragraphs that could easily be summed up in a few sentences is a DANGEROUS waste of the time of anyone reading it

did i secure the load leaf with some form of clip, yeah the same one they use in stock applications....which seems to be non existant
flatter than a stock spring pack and pushing down on it? yes the load leaf is big and straight, doesnt bend easy...makes for a good flattener
yes its inverted....other wise it wouldnt do a good job of lowering the car
im sure if you look through my photo album you will catch a glimpse of it in one of 2 pictures

a ute load leaf should be too hard for demo to find...as he has a ute

you may think that pushing one spring down with another is counterproductive....well yeah im countering one spring with another to make the first spring push up less, hence the lower ride height
it also preloads the spring and makes it stiffer

you wonder why this practice is not widley adopted, maybe its because not every one has ute load leafs lying around as you said
and im sure many budget racers use a similar method to what i have done, but im also sure that many racers would also like a bit more tuneability than a big leaf pushing on some not so big leaves, hence the paying to tune the suspention to what they need

maybe i should take my car to get a roady just to see what they say, my bet is on them not saying anything as they would have no idea that its not supposed to be there....also anyone doing a raody on my car would have far more exciting things to look at like the "dodgy" home made engine conversion diff conversion brake conversion and any other modified part of my car
someone who actually knows would say something like "anything not stock should be engineered"

im sure many people would go to a shop and be happy to hand over money, but just coz you cant do something doesnt mean every one else is the same

after typing that i really dont see how you can actually churn out all these long posts
edit: and oh my god its not even as long as your last post
