So what are the stock sway bar sizes on the Ea-82 cars? Specically my '92 Loyale...What is the GL, GL-10, RX, etc...What is the size of anything that will interchange?

Look here:

Excellent - that chart is great! Except it still doesn't have the loyale sway bar sizes...or if it even has one.

check "Stabilizer Bar" (first line)

 

My '88 RX is 18mm front and 16mm rear. I want some XT6 20mm front and rear bars.

same as GL/DL

Thank you chucks. That's what I needed to know. So is it worth installing 20mm xt bars? Is there that big of a difference in 4mm? I know the stiffness goes up exponentionally with diameter...but does it make a big enough difference to be worth the effort?

I went to 20mm front and rear.

 

Huge difference.Combined with my suspension, understeer is a thing of the past:D
