My son has 93 SC 400 Stock. We just put in BC coil overs he wants to up grade the suspension we are thinking of sway bars, any suggestions.

Supra TT or Titan sways (for supra but will fit on an SC).
I have the Titans, theyre 3 way adjustable in the front and 2 way in the rear. I have Megan coilover and the car handles like a go-kart on the highway

Thank you I will try it.

Whiteline sells sway bars specifically for the SC. OEM should be hollow steel, whitelines are solid spring steel and adjustable.

I just called enjuku they say Whiteline as well.

I would highly recommend getting the supra sway bars.
the rear mounting points are in a better position which allows for less twisting vs the stock sc ones.

^^^Whitelines mount to stock position and will outperform an oem supra sway bar, 22mm solid not hollow spring steel 3 way adjustable. When it comes to the subframe mounts bushings being inferior on the SC thats why theres battleversion, superpro and shopfigs.

the stock position is not a good position to mount too! (not the bushings)
The mounting position in itself causes the sway to bend/ twist
the supra's mounting points are much more direct which causes less twist.

supra sways are honestly the best upgrade unless you get the daizen.

So you think you know better than the toyota engineers?
Sway bars are supposed to bend/twist - that is how they function.

Same sway bar setup can be seen on 1st gen GS, toyota chasers/mark 2's in japan, lexus LS.

Daizen bars utilize larger diameters instead of adjustability. You can achieve just as great ability from the whitelines because of their adjustability - they are defeinitely much lighter which would mean less unspring weight.

OEM locations work perfectly fine.

whats funny is I am actually an engineer for Toyota hahaha
the reason why they are mounted the way they are is for more of a luxury feel (soft lots of body roll when cornering)
the supra has different mounting points to provide more of a race feel (hard, little body roll when cornering)
its not always about the bar, but how it mounts.

Hollow bars > solid bars any day of the week. The center just adds weight and does nearly zilch for torsion properties of the bar itself. A large diameter hollow bar is preferred in applications where diameter and alternative bushings are permitted.

I can't comment of location. I took my rear bar off entirely so my preferred mounting location is somewhere on the floor in the back of the garage underneath OEM parts.

well, material selection has a lot to do with torsion properties.
and also, the stress would be less with the solid bar vs hallow bar (more weight) stress=Torque/mass^4

and you are absolutely correct. you really don't need a rear sway bar. you only need a front sway bar.

Stress on the bar itself Hollow bars do occasionally fail but it's quite rare. I've seen 2 fail before at the track and that was on a 350Z and a WRX that took some time off-course. Both ran hollow Hotchkiss IIRC which isn't even available for these cars.
