Post 2015 Q40 AWD Swift Spings, Cusco Strut Bar, Stillen Rear sway, Bell OEM brace

Hi,

Relatively new owner of a 2015 Q40 AWD, which is pretty much a G37x. This review isn't that detailed, but more of a notice to Q40 and/or AWD owners that these parts fit fine. I had been driving an IS300 Sportcross outfitted with Koni yellows and an Eibach spring/sway kit for the last 17 years. The car handled like a go kart, and i needed a bit of that feeling from the Q. Stock, the Q is pretty sloppy. Tons of body roll and the OEM tires are terrible. I ordered a set of Bridgestone RE980s from Costco. I wanted to stay with the stock 17" wheels so these are a great all season choice. Immediately the car handled better, but it was still rolling heavy. I had a shop install the Swift Springs and Cusco strut bar along with a full alignment and underbody inspection. My son and I installed the Stillen rear bar and Bell brace. The car handles really flat now and has that nice rotation feeling in turns. Stillen claims the bar does not fit AWD, but that is because it is sold as a front/rear pair and the front definitely doesn't fit. The Stillen is 25mm diamter vs 17mm OEM so I bought Energy Suspension bushings and brackets. I used the stock end-links and greased the new bushings with Mobil1 synthetic grease. The diff brace was easy to install. Did both while the car rear was on ramps.



Stock, note the wheel gap.



After the Swift install, much less gap, but not a crazy drop.




Stillen rear bar vs OEM.....lol




all the new red stuff. Swift springs, Bell brace, and Stillen sway bar.
