Hi, I have read on here before that it needs to be on all four wheels before tightening them up fully. I can't remember why, but someone will
be along soon to confirm it's correct.
Thought I should mention it, just in case

I think that's if you are using the Truimph Herald rubber type bushes - the indy bushes are PU and are not fixed to the centre crush tube like
the herald ones.

Yep if you're using the Truimph Herald type on which the crush tube is fixed then yes keep them slack, sort out the ride height etc and tighten
them up, thats what I've done anyway.

P.S Mooky you still working too hard?

If using the usual poly bushes and steel crush tube then the bolts can be done up with the car in air and wishbones at any angle. Do them up good and
tight as you want to hold the crush tube nice and tight in the chasis bracket and ensure that it's the bush rotating on a fixed crush tube.
Make sure you grease the bush/tube interface whilst assembling otherwise they will suffer stction and squeak like a bugger forever more.
For the shock bolts, unless you're using shocks with rod end type fittings, you want to wait until the car is on it's wheels with the full
weight acting on it and the ride height roughly set. then pinch the bolts up tight. This avoids over stressing the metal/rubber bond of the
metalstic bushes of the shocks.

Thats the right torque for rubber bushes. Polybushes need to be done up to around double that to be sure of holding the crush tube tight in the
brackets.
The recommended torque variues depending on the bolt, but will take it to ~75% of its yeild strength, this is the point at which it produces the
optimum clamping force.
For an 8.8 grade M12 this is approx 100Nm
