I have a Genesis coupe 3.8 that came with factory sway bars that worked well but I wanted something a little…stiffer. So I went with the thiccest & heaviest sway bars available which were whitelines (also got the endlinks). After tossing them on I tested them out on my road with several 25mph curves (desolate country road in Mexico btw) and the difference was super noticeable. Like I literally started laughing when I felt it. It was a lot less body roll and felt a whole LOT more planted than with stock bars. I imagine people going from no bars to these would think they just hit the Konami code. I am no professional driver but felt comfortable pushing an extra 5-10mph on curves that I’ve driven for the past decade. Mind you this was when the rest of my suspension was bone stock. Pairing them with my full setup now is just bonkers. So I would 100% recommend these and specifically from springrates because they hooked me up. UPS lost my rear sway bar and literally delivered an empty busted box (which was mad disrespectful cause he knew there was an issue) but I emailed springrates and they said it’s no worries and they’d send another one out immediately. The next day I got another tracking number and boom. If this sounds like a paid review I swear it’s not, I’m just excited about these chunks of metal that help me impress my stupid friends lol Follow my gram @djinncoupe
