There is no higher quality than oem. There are adjustable links, which are only useful if you have adjustable suspension height, so you zero out any swaybar preload, especially after corner balancing.

If you don't have adjustable suspension, you are just buying something that will wear out quicker than stock but provide no benefit.

 

I forgot to mention I’m also planning in buying coilovers. Currently it’s on stock height but I plan to drop it an inch. Will track occasionally one or twice a year. Do you recommend I go with with adjustable since I’m installing new suspension ?

 

Hardrace is supposed to be an OEM replacement.
I went with Anorexicpoodle's adjustable links with my Eibach bar. I think you only really need adjustable links with aftermarket sway bars.

 

No. The only reason for adjustable swaybar links is to remove preload from the swaybar. Swaybar preload is not because of the swaybar, but because of the suspension. The coilover height left side vs right.

If your suspension is perfectly level, no adjustment needed. The only way there is going to be enough preload to make adjustable links worth tje effort, is if your adjustable coilovers aren't set the same left vs right. The major reason they might not be even is if corner balanced the car.

So it can be said that you really only need adjustable swaybar links is if you are actually corner balancing your car.

 

any particular brand for adjustable sway bar links? i've been reading about whiteline.

 

With fixed endlinks, swaybar preload occurs when there's any left-right weight imbalance, regardless of whether the car's corner-balanced. Since the driver sits on one side, it'd be highly unusual for there *not* to be any preload.

However, as the track-day community has known for many years, the real preload issue with this car is that nearly all of the "easy" weight-relief tricks are on the right side of the car:
- Battery (15+ lbs)
- Header (8-10 lbs)
- Exhaust (25+ lbs)
- Spare tire (23 lbs)
- Passenger seat (33 lbs)
- Airbox (5-10 lbs)

That's 100+ lbs of weight relief from the right side of the car, on top of the 150-200 lbs of driver added to the left side. I tracked my car in this config, and when I had it corner-balanced the endlinks were essentially at max length on one side and min length on the other; and the ride height was set so high on the left rear that the car looked like it was trail-braking standing still. But man, once you got it on track, it handled like nothing else.
