My car has Slotus disease. There I've gone and said it. Thankfully there is a cure. The Gonzo/CR suspension mod is guaranteed to fix even the most wayward front end. At least I think there is a guarantee. There are lots of pages of build log to go through and I'm just going on memory here. I think if it doesn't work you get a free goat. The whole discussion is right about here, give or take 10 pages.
viewtopic.php?f=35&t=8526&start=2385The short version for those that don't want to read 30 or 40 pages or have an aversion to goat jokes is that moving the upper spring mount out towards the tire will make the coilover more vertical. Leaning the spring over reduces the effective spring rate softening the suspension meaning less control over suspension movement. Once again I'm working from memory here but I think that was the basics. Anyway Gonzo applied the fix to his car and the car was immediately faster. Or maybe it was painting the intake manifold green that did it. Hey, there are more than 200 pages there. I read them all once but that was a ways back.
So here is the front suspension of my car.

See how the coilover is laying down on the job? The coilover is out of a Caterham so I'm guessing that the spring rate is close to what I need. The suspension bottoms out when the coils compress to where they become a solid unit. Not a good thing. I'm going to use a 1.5" square tube to make a new mount that is further outboard and a bit higher. First off I measured the bolt to bolt length of the coilover with the car sitting on the floor. Then I made up a spring mockup that is the same length. Here it is with the uncompressed coilover.

Then I had to clear the air cleaner and it's mount out of the way. That meant grinding off the brack...um mounting thingy. I think that means that I've now ground off and replaced just about every mounting thingy on the car.

The turbocharger something or other valve was also in the way so part of the induction piping had to come off as well.
