Installing coil over questions

Hi Guys,

So I got some coil overs from Rebel Racing, Clint is a great dude, very helpful, highly recommend, so much suspension knowledge, he even talked me out of getting the more expensive shocks...

So anyway I have written a list of how I think I should tackle the job this weekend. Any feedback would be much appreciated. The car is at stock rear height so looking to drop that too. I'm also having it all aligned and corner balanced once I stall the shocks and the new front suspension Clint is making up for me (raised spindles etc).

1. De-torque rear wheels, chock front wheels.
2. Jack car up via engine crankcase, where do I then put the stands? I always use the torsion bar tubes!
3. Remove wheels
4. Disassemble spring plates
5. Take note of spring plate angle with angle finder
6. Remove torsion bar cover
7. Re-index torsion bar, not sure to what angle (stock 88 carrera bars)
8. Reassemble setting the spring plates in the middle as best as possible.
9. Take car for a drive and see where the suspension settles
10. Install coil overs with the least amount of spring preload
11. Adjust preload until it just starts taking effect on the cars height.

So this is what I imagine, not sure if I should make the car really low then raise it but I guess I would like the torsion bars to be taking most of the load at rest as the shock towers aren't re-enforced...

Thanks guys as always!
