I actually managed to install a Whiteline Front Sway bar on backwards loool

Backwards?? Do you mean upside down?
They are very easy to fit upside down by mistake, as I found out once myself.
Made it very hard to fit the links lol.

Holy crap I also thought they were only needed for upgrading sways! I have stock suspension now but it might go BC Inverted coilovers maybe within the next year so might have to invest in one of these you reckon?

 
With stiffer suspension there will be less suspension travel making the sway bars deflect less. This means less strain on the mounting points and lower chance of breaking something. 

That's great news! But ironically wasn't it the stiff suspension and slicks that made Whitchy's SW20 rip it's sway bar mounts?

Woo hoo! mines pretty stiff...
now it just comes down to how hard you're pushing then lol

Mine are cracked apparently. Stock swaybars, stock struts, king springs. I must really throw the car around! Lol.

^^  Those cracks appeared on cars with lowered suspension no?

The pic I showed of chassis cracks happened to a '90 model with stock springs and stock swaybars.
 
Another thing to watch with poly bushes is that they should be a good fit , and not squashed out when the brackets are tightened that can cause mount flexing.
 
Also poly bushes need to be regularly lubed with something like Nulon extreme performance grease.
 

oh great. another thing to worry about lol.
 
better check mine when I do the bushes and get reinforcement plates at the same time....

Angle of the dangle.
Most of these problems can be attributed to the angle set between the bar and end links at kerb ride height. When the endlink length is such that the bar ends are horizontal and the angle is close to 90deg, little force is absorbed by the bar mounts and most is absorbed by the bar.
When you lower the ride height, have weak or sagging springs, or over work the suspension to the point of bottoming out, on stock length end links, things change dramatically. As the angle increases, more force is exerted on the bar mounts; in some extreme cases, particularly with adj height coilovers, the bar end to end link angle can reach 180deg and actually invert the direction of rotation, locking solid, hence all the reports of torn strut mounts and cracked bar mounts.
Adjustable end links are good insurance on modified suspensions.
