Alignment Finishing

Tried to attempt assembly of handbrake, discs and caliper carriers but first decided to have a last check of the toe, and borrowed a digital inclinometer from work to check camber (although its non-adjustable).

The reason for this is that although in the manual it says to set the toe/alignment off the upper forward mounting lug and then measure the space in the other 2 lugs and fill appropriately, if you were to be ±1 shim in the lower forward lug and then did up the nut effin tight you could inadvertently alter the toe and potentially the camber depending how bendy everything is.

Due to dissasembly for messing around with driveshafts, then reassemby, the aligment measurement for the rhs was out by 3mm at the front of the car which is near as damn it one thin shim (0.15mm). Maybe I wasnt quite so brutal in doing up the nut as before but anyways we were getting sick of the iterative measure-adjust-remeasure process and the manual says within 2mm either side is good enough.

With all shim packs inserted and everything done up good and tight, my toe readings were 0.5mm greater at the rear of the setup bars, giving very slight toe in, and 1mm difference at the front although the width of the laser at that distance gave another 1mm potential error margin so we reckon it was as good as it could be. Out of interest the camber measurement was -0.2° and -0.1° driver and passenger side respectively. Probably not going to get much better than that and the target is 0°.

This meant that the handbrake components could go on, followed by discs.
