I've heard rumor that subies endlinks are weak. If you lower your car and one tends to autocross fairly often/hard then you can break them. (If you have upgraded you sway bars you definately should have upgraded endlinks.) Is this true or false?
Those Endlinks don't look all that stable to me..just on a look..I have never used them so I dont know for sure
The stock endlinks are pretty weak and aftermarket ones will help you out a lot as far as suspension go's...PM me if you would like some I can hook ya up for sure
if I had to do it again, I'd get cobb's in the rear and kartboy's in the front.
Kartboy's are padded so they're not as precise as the cobbs but I can't live with the pinging from the metal on metal in the front with the cobbs.
I don't think it's fair to say endlinks improve handling nor that getting just a sway is silly. The main benefit of endlinks is better handling feedback to the driver allowing the driver to make better decisions and adjust to what's actually happening with the car.
The oe links aren't very likely to break- as moss points out their inherent weakness is the rubber bushings they use- they are very soft. soft bushings deflect more and with a sway bar this extra deflection delays the working of your sway bar. In a gentle sweeper your likely not to notice it much, get into some fast transition stuff (like a slalom) and you will very much notice the difference between a good aftermarket link and oe
A pillowball/spherical link provides the least deflection, but most most likely to add NVH- if the bearings are not of high quality they can often die pretty quick. They are often also height adj- this lets you adjust any pre-load out of your setup. For all out racing applications they are the only way to go, for other applications a uprated non-spherical may be the way to go
