Sway bar recommendations-Drift only application

[Spdrules5]

I need some opinions and facts on this matter. First, my car:

'89 240 coupe w/ SR(maybe 230 rwhp)
GP Sports inverted coil-overs(non adjustable valving)
Home made Nismo powerbrace
CP racing triangulated strut thingies front and rear
TC rods, new lower control arms, Battle version RUCA's
Peak performance inner tie rod ends, S14 Tein outter ones
Box'd the frame rails on car(Great results!)
Good Drift alignment from good shop
6 point cage coming in January
Stock sway bars---

I only use my car at monthly drift events- Drift Buffet/Land-Ho.net, Driftday, Just drift. I was going to get Whiteline adjustable sways, but started thinking if I really need all that adjustability. Or if any good brand(???) of non adjustable sways will work best in my application. I

Maybe even some local places in So. Cal-Long Beach to purchase said sway bars.

Thanks
