I am not a big fan on solid end links.

A good sway bar will give you same results without having you to swap the endlinks. See, the endlinks serve a purpose. They act like a fuze in case you smack into a curb ot something. They simply snap. If you do the same with solid endlinks, you will bend a whole bunch of things.

Solid attachment is a good investment.

My personal preference is CUSCO front, CUSCO rear w/ solid attachment.

 

I agree, that when using a heavier bar such as the 22mm adjustable, a heavy duty mount is a good investment. I've seen stock mounts break from heavy bars and its just good for peace of mind to install them.

As far as solid endlinks are concerned, they do serve a function in providing the bar's anti sway/roll properties at an earlier point compared to the stock plastic one's. For max performance this a good thing as the car will behave more predictably because you'll only have the rate of the bar to contend with and not the "dual" rate of the plastic endlink. However, as with any component that strengthens an application, the stresses of the road/impact have to go somewhere so one may encounter increased wear on areas associated with the part. They may serve as a "fuse" as Imprezer states but, to tell you the truth, if you smack a curb, you're going to bend/break something and a plastic endlink is not going to save you much.

 

I recommend Cusco sway bars due to the fact they follow the factory bar design (only bigger and adjustable). Even the included bushings are of the same material and quality as the original, unlike the whiteline bushings.

As far as endlinks go, I recommend the solid noltec and new whiteline aluminum endlinks- I sold my Noltecs a few months ago while considering selling my car, but changed my mind and installed the New whitelines tonight (already using the cusco bars front and rear)

By the way, Gruppe-S has the best prices on Cusco!
