I'm not going to lose any sleep over it!
Having driven it, I'm feeling 3.23 is still too short, so at some point I may consider a shorter ratio.
A few pics, they always seem grotty, I suppose the underside of cars generally do.
I did a few fixes like the below on the heatshield that was on its last legs around the bolt holes - I intended to buy another but only remembered when I was putting it all together, so this will have to do:


Did some general flapwheeling, kurust and dinitrol to clean up the subframe etc.

General impression is the ARB and suspension bits at the rear make it much tighter, the eibachs sit perfectly and are noticeable both in terms of ride height and ride - from what I'd read I was expecting them to basically be the same as oem sport springs but am glad that they're a bit more sporty and a touch lower. The diff is noticeably shorter but I'm annoyed I didn't go 3.38, I think it would have been better still and it still feels a bit long. The LSD has definitely improved traction but I've not really had chance to push it.
Maybe at some point I'll consider selling the diff complete and try a 3.38, no rush though!
Good to see it all back together Tim, but was expecting to see the undercarriage as clean as the examples by this Dutch guy!
