What's a good upgrade from stock that's currently available in 2022? I mean, I know swaybars are part of the infinite variability of suspension tuning, but is there a go-to, Easy Button, 80-20 solution setup the community has found in the last 30 years for a street car that sees some track days here and there?

I'm on a 9k/7k GC/Koni Yellow setup with the stock bars. Honestly, the car is pretty good this way, but I think there could be improvement. Balance is pretty good, maybe a little pushy with my current staggered tire setup.

Do most people swap both bars? Front only? Rear only?
The front sway bar mounts do well with replacement/reinforcement, right? What's the go-to solution there? (Again, that's still in production)

 

What year and trim is your FD? Both bar OD sizes vary, the rear moreso.

Racing beat is one viable option for sway bars, and Sakebomb Garage makes the front mounts:

FWIW I auto-crossed for a few seasons with my Tri-point adjustable swaybar on the middle setting and an RB swaybar mount brace and the stock swaybar mounts with no issues. If you like easy, that brace is a lot cheaper and easier to install.
If you have understeer and are keeping the staggered tires I think you want to stiffen the rear, not the front.

 

It's a 93 R1.

 

Very happy with the RB F&R sway bars for my 93 RX-7.

Have them set on the stiffer setting for both F&R and very happy with them. Much less roll. Made it a bit easier to rotate the car which I preferred. Obviously a heavy foot can get the back end out, but I feel that the RB sway bars make it balanced towards oversteer if that makes sense.

 

I followed Howards advice in his chassis setup thread. You can get the front bar in the same specs from mazda motorsports and then go with the 95? bar in the rear. His thread details everything.
