Whiteline rear sway bar installed...
Removing the stock bar was relatively easy, installing the Whiteline bar was going well until I went to tighten one of the upper sway bar mount bolts...
Managed to cross-thread the damn thing! (many expletives were used).
After a very sedate trip to @Subirex Automotive, a quick rethread and some power tools make the rest of the job a lot quicker.
I must say, I had high expectations for the 22mm bar, and it exceed them.
The car is way flatter through the corners, allowing me to go significantly quicker on entry and carry the speed through the apex.
Surprisingly very little negative impact to the ride comfort. Almost makes it more comfortable due to the lack of roll.
Would definitely recommend all the 5th Gen owners look at doing the same.
