Amazing turning

Installed this on its stiffest setting right off the bat and made the rear so much stiffer, combined with some camber in the front and some coilovers, the car takes corners so fast and so easily. I feel a lot more confident speeding up to catch a yellow left turn arrow at a stop light! Installation was a little tough since my coilovers were too low making the sway bar not go right over the LCA's. Also, at low speeds I hear some popping noises in the passenger side rear of the car. All bolts are tight and my endlinks are straight so I am not sure what the issue is. Overall great product would highly recommend 10/10.

24mm whiteline Sway bar and endlinks

Handling is fantastic and I just started with medium setting. Can't wait to try stiffest setting. However install was not quite as easy as I initially thought. I needed to use 2 lg. Washers on inside of endlinks because there was too much running torque. And needed a pry bar to get one side of sway bar around the bracket it connects too. But over all happy with results.

Like it tight!

Was torn between 22 or the 24 and it decided to go with the heavy duty and one of the best decisions I made it made the rear a lot more planted in corners pair it with some d bushing and front end links to compliment the rear and your good.. well worth it. Note: you don’t need to take out exhaust mid pipe or any of that I did it in 30 mins most bolts aren’t crazy tight and went to town

Great bang for buck mod

MAPerformance processed my order in great time and sway bar came in perfect condition. Set on stiffest setting and feels great over stock. You don’t get thrown around in the poorly bolstered stock sti seats after installation. Would definitely recommend for for the price.

Noticeable improvement in handling

Install was straight forward and fairly easy. My only complaint was that the original bar i was sent was noticeably bent uneven on one side and wouldn't line up with the left side endlink. M.A.P took care of the issue quickly and sent me a new replacement. Car feels alot more neutral around corners with about 50-60% less rear body roll. I have it set on the middle setting, paired with whiteline's adjustable endlinks.
