Lowering the sping platforms to acheive ride height.
Discussion
I was just about to circlip groove and lower the platforms to the bilsteins to acheive a 10/15mm lower ride height then realized the shocks being on the angle, also rears more pitched than the front that it's not that straight forward.ie 10 difference in diagonal coil height wont give me 10 mm of vertical.
Has any worked out or calculated when lowering the car what adjustment is required on the platforms to acheive different ride heights.

It's simple trigonometry, but if that isn't your cup of tea trial and error is pretty foolproof.
Yes, however I still need to work out the exact angle of front and back with a stripped chassis,trial and error isnt my cup of tea,maybe I should just machine a thread on the body.
The trig is simple once you understand the problem, but a bit too complex to explain without diagrams. Really, trial and error is the most sensible approach if you aren't familiar with trigonometry.
Put it this way: with the suspension assembled without springs and set to the normal ride height, measure the damper length. Move the suspension to your desired ride height. Measure the difference in damper length. That's how far you need to move the spring seat. Bear in mind that changing the ride height can change the suspension characteristics significantly. You probably won't get into trouble with half an inch, but don't be too ambitious without consulting an expert.
If you're seriously thinking about machining the dampers you should consider getting an adjustable spring seat instead.

Hopefully your springs will also be long enough ..
Don't forget when you go over a ump back bridge the whole suspension is fully extended and if the spring is not long enough may well not re-seat properly...

Spoken to the Bilstein guys here,1/2 inch no probs,spoke to Derek too(sorry, probably woke you up.Would of preferred to look at a set of eibach's but you have to make do when your in the backwaters of the world.
Last Bilsteins I regassed to a setting I liked,just want to take it a step further with a little height adjustability,still works out a hell of a lot cheaper than if I end up selling the car with the Ohlins left on, and in the meantime still get some enjoyment out of a better handling car.
