Ok, stats for toe change on a 6° rear beam across the range of travell, as robbed from Rainbums ultimate spec Sapphire thread.... Assume it's an Ahmed/SCS beam the readings have been taken off as thats whats fitted.
Rear: Independent, by semi-trailing arms, LEDA adjustable 2¼" coilovers with 171lb springs and Escort Cosworth 22mm anti-roll bar. Ream beam replaced with an Ahmed Bayjoo modified (Grp A) 6°
item, rose jointed and fully adjustable set to 1.5° negative camber and 0' 20" toe-in. Polyurethane rear axle bushes and Sparco rose jointed rear strut brace.
Rear bumpsteer:
Bump
60mm - 0.030" toe in
50mm - 0.023" toe in
40mm - 0.015" toe in
30mm - 0.009" toe in
20mm - 0.005" toe in
10mm - 0.003" toe in
0.0mm - 0.000" toe in
Droop
10mm - 0.001" toe out
20mm - 0.002" toe out
30mm - 0.003" toe out
Just looking for standard figures to compare to.

Also. You say about a slotted inner joint being negative. Dependant on the cars body obviously our beam could be better or worse than 6degree.
The 6degree is made bang on the centre of the slot if I am not mistaken. And with it being toe adjustable on that slow a tiny tiny amount makes a big difference as it's across the arm. So if your being anal about it it could be a 5.8-6.2 for example

if the 2 rose joint beam is adjusted for different toe that will also wont be 6 degree anymore. it will only be 6 degree at the toe it was made for?
also you are moving the wheel forward or back to get toe movement, so you could end up with one wheel in a different pace to the other side, with the slotted beam your wheel stays in the same place no matter what toe you have.
also the beams with a bit or pipe welded in, i know of 2 that have bent without any impact.
scs trailing arms are stronger and look more factory.

It's not a case of one setting fits all, it depends entirely on how the car is intended to be used, so you tailor the settings to suit 
.
I have tried the Zoo beam and Ahmed's / SCS beam and they were both equal handling once fitted to the car. The only thing with the double adjustable Zoo beam was that it was VERY tricky (more time consuming) to set up due to adjustments made on the toe affecting the camber as well and the bolt that came with it as standard wasn't long enough (I've even heard of people's falling out
). Obviously it was nowhere near as well made (as has been commented on), but even Ahmed said that despite this aspect, it was one of the better ones he had seen.
At the end of the day, you pay your money and make your choice. If you buy one of the following beams, I'm sure you won't have any issues what-so-ever:
SCS
Ahmed Bayjoo
Turbosystems
MK Motorsport
Get it wrong though and the car can handle worse than with the standard beam.
The beam is one of the BEST things you can do to a Cossie and if you want to understand why, read my article I did for Fast Ford:

Tim, its moving TINY amounts, as I said a tiny amount of adjustment on the inner effects the outside massively! So its barely changing, it may not be a 100% fixed true 6degree beam but its so close to better or worse dependant on cars. Smething you would never notice.
Its like going to 7 or 5 degrees you wouldn't notice the difference but going 18-6 degree its huge. Any were taking 0. Something degree difference.

Can someone show me in English lol the exact difference between a STD 18 degree and a 6 degree Beam
What I mean is, 6 degree is what angle?
Next winters project on my race car will be a new beam to try and reduce the oversteer more power has brought me lol

it will not effect the handling at all ,just maybe when all set up geometry wise the bolts might be in a different position in slots no a drama mate ,just like when you time verniers pulleys might be in different positions but still timed right
thanks mark
