Stiffin it up!

The STI already has a decent sized sway bar from factory but this Whiteline kit is an excellent upgrade. The factory mounting points are unsupported and Subject to flexing but the braces in this kit correct that. Very happy with the quality from whiteline.

Tight fit but BIG handling difference

Install was pretty smooth except for the last bolt going through the lower control arm. This combined with my CUSCO strut tower braces made a major difference in handling, I can't help but take 70mph turns on the on-ramps to the highway now.

Another great product

Easy to install. Actually comes with paper instructions which helps (although the paper instructions have formatting issues so there are no spaces between the words). Helps with understeering and body roll.

2nd set - Love Whiteline

I had a full Whiteline suspension setup on my 13' WRX with ISC Coilovers. Purchased these for a 2020 STi with the same expectations of quality and have not been disappointed. IIR delivered fast and with great customer service. I will be picking up another set for a 2019 STi in the near future.

Whiteline sway bar kit STI

I recently purchased a Full whiteline sway bar kit from IIR. Fast shipping as always! my car has Fortune auto 500 coils, Beatrush braces, bushings, etc. and voodoo13 LCA's. even with all the other suspension mods there is still a huge difference in handling. I have my sway bars set to full stiff. the biggest thing ive noticed is that the steering input is much more responsive. when cornering the front end also feels lighter, with a lot less dive that I couldn't tune out with the coil overs. the rear did not have as much change in feel, but definitely has more grip when cornering.
