SC - Carrera Sway Bar Specs

[Superman]

I'm confused.

I believe the sway bar sizes went from 20/18 (F/R) to 22/21 in 1896. In other words, they were 20/18 in 1985, and then 22/21 in 1986. Correct?

Then, the next year, the G-50 transmission came out. Did these cars (with the G-50) have a different kind of sway bar?

I am trying to upgrade a 1978 SC. I have been told that Carrera sways will work well, and I wonder what model year(s) of Carreras to look for.

Yes they did change in 1986 to thicker bars.

For the upgrade ideally you would want '86 bars, but the later G-50 bars will also work. The only difference is that the G-50 rear sway bar will hang lower to get around the bigger G-50 transmission. If I recall correctly Noah did this to his car and he loved it. I have '86 bars for my car, but I've never driven my car.

You ask about sway bars but give specs on torsion bars ...... Which is it?

[Superman]

Nope, those are sway bar diameters in millimeters.

All '86-'89 22/21mm sway bars work, great upgrade for street & occasional track.

FWIW- on my street car I am still running the original rear mounts w/ 22/21 s-bars. No issues after 8 years and occasional track use.

Thanks, guys. I've sourced some '87 sways. They should work nice with my fresh shocks and 22/29 torsion bars. Woohoo!

If I break a sway bar mount, I'll fix it.
