First, a big thank you to all the early adopters of these. Anyone who has read the entire thread will have learned a lot from the reviews, writeups, modifications, and things to look for during install.
I'll also try to add some useful info: Anyone looking at upgrading the bolts (since it looks like a few have either bent of failed completely) should look for M16 bolts and nuts Edit: I cannot measure things properly. Those should be M14 bolts and nuts, M16 is too big! The existing bolts are 130mm length, but 120mm will also work. Class 10.9 should be equivalent to Grade 8. McMaster-Carr part numbers are 95327A795 for the bolt and 94645A250 for nylock nuts Edit: 91290A774 for socket head bolts and 99908A105 for locknuts, so about $20 for both sides delivered.
Finally, there was a request a while back for before/after alignment numbers for just changing UCAs. I swapped UCAs and replaced my 2.5 front spacers with 5100s @ 1.75 and Moog 81108 coils, but my height only increased ~0.25" so I have a decent set of numbers for comparison (compare the after values from the first data set with the before values of the 2nd set).
2.5" Daystar on stock UCAs 8/19/14
Left Camber: .5 before, .2 after
Right Camber: .4 before, .2 after
Left Caster: 1.3 before, 2.0 after
Right Caster: 1.6 before, 2.3 after
Left Toe: .27 before, .05 after
Right Toe: -.2 before, .05 after
SAI (both): 11.5 before, 11.7 after
Left Included Angle: 12.0 before, 11.9 after
Right Included Angle: 11.9 before, 11.9 after
5100s @ 1.75, Moog 81108s, Suicide UCAs 7/6/15
Left Camber: -1.5 before, -.7 after
Right Camber: -.8 before, -.6 after
Left Caster: 4.8 before, 4.0 after
Right Caster: 5.0 before, 4.4 after
Left Toe: -.9 before, -.01 after
Right Toe: -1.52 before, .01 after
Left SAI: 12.6 before, 11.9 after
Right SAI: 12.9 before, 12.9 after
Left Included Angle: 11.2 before, 11.3 after
Right Included Angle: 12.1 before, 12.3 after
It looks like these add ~3 degrees of caster (while totally throwing out your toe and camber, so predictably an alignment is required).
So...that's something, I guess. Hope it helps!
