Bought this just to spice up my engine bay a little bit, and ended up actually surprised on how nice it felt on the corners. Great quality

It fits!

Ok, so I’ve got an IAG AOS, Grimmspeed TMIC and was worried about Cusco strut tower brace clearing. I couldn’t find anything online where someone had already done it with the same problem. But it fits and looks good, might powder coat the bases red to match the engine bay, but super stoked.

Great strut bar that is proven that clean the IAG AOS

Not many strut bars out there can clear the IAG AOS in the original mounting locations, this one can and with having onlins coil overs already installed this just put the icing on the cake as ohlins keep you planted in low speed corners, this adds that extra security in turns or sweepers at high speed

Balanced Ride

Installed on a 2019 STI base w/ stock suspension. Added the cusco X-brace first for the rear chassis flex which was felt right away when trail braking and then recently added the cusco front tower strut. The front strut gave me a more immediate steering feel and the car felt more neutral and controllable when combine with the rear x-brace. I did not get an understeering feel like I did with the OEM STI front tower strut bar and the fit was a lot better too. No added NVH and if you get squeaks just lube w/ white silicone and the noise is gone. Great cornering out in the tighter canyon roads and def worth it for the WRX/STI’s that have some mileage on their chassis. Great purchase experience and packaging from IIR as always.
