Default Simplest rear sway upgrade?

I'm kind of looking for plug and play. I know it's only a modest upgrade but I was thinking of the 19mm STi rear sway for my '13 WRX since it's only $100 for the bar and bushings, and can use my current end links. This way I can just hand the parts to my shop and say - "here, put it in" without having to worry about them needing anything extra.

So I guess I'm looking for a suggestion on what other modest bar wouldn't need any new end links, just buy the bar, bushings, and hand it off to my mechanic.

I appreciate any input, and am not looking for this to be a sway bar debate, as have read most of the other threads including various "manifestos" on how they work and what they do. This is a daily driver only, but of course we all like tackle the corners when the opportunity presents itself.

Also, if I go this route, is items, 1, 2, 3 on the attached diagram all I need? Is item 4, the 'stabilizer link' the same as an end link, which I dont need going to the STi bar from my stock one?

The 19mm bar is a pretty good upgrade for the price, and you shouldn't have to upgrade the endlinks, My OEM ones are just fine after a year of use with the 19mm bar.

I also have the whiteline support braces (KBR-15) for extra support, it wouldn't hurt to get those in case you upgrade to a bigger bar in the future.

This is so confusing. Now i'm debating the 19mm Sti bar for $100, or the 20mm Whiteline for $152

Allow me to confuse you even more. I would skip #2 and #3 in the parts diagram, and just buy some 19mm poly bushings from Energy Suspension or Prothane.

If you elect to go with the Whiteline bar, it will come with new poly bushings, so there wouldn't be any need to buy anything else.

Oh, and a rear sway bar install/swap is painfully simple. There's no reason to pay a mechanic to do it. If you don't have the tools yourself, find some other car enthusiast you know that does.

Do the swap of bar yourself. Depending on the hardware change 12, 14, 17mm are the sizes. Easier to swap the endlinks as well at the same time if you are going to upgrade hardware more.

20mm whiteline bar, kartboy rear end links and about 30 minutes of time and you are all done.

Okay, going to make this simple. My 2013 WRX comes with 21mm front and 16mm rear. Quick and simple. My choice is between the STi 19mm rear, or the 20mm Whiteline rear. Even though they're close I'm thinking the 20mm Whiteline, keeping the front and rear as close as possible to give it a more neutral feel.

Which would you choose between these 2 ?

If you want to keep using the stock end links buy the STi bar. If you are willing to swap the end links buy the whiteline bar.

The stock endlinks on the GH/GR chassis are surprisingly sturdy, there is generally no need to upgrade them unless you go with unusually large bars. I have the RCE 25.5mm hollow bars with stock endlinks on my 2012 WRX and no issues whatsoever.

I would say there is no need to upgrade the endlinks if you are sticking with an OEM bar. If you go to an aftermarket bar you will definitely want endlinks as it is very difficult to make use of adjustments on the aftermarket bar with stock endlinks.

My 2012 WRX has a 22.5mm front sway bar as a stock unit and 16 rear so I ordered a 20mm for the light rear end. I wanted the side movement to b balanced with a small amount of sway for weight transfer n to b less likely for the car to slide in a panic turn. This street set up seems ideal to me. Good luck
