I can't remember exactly which model KYB I put on my 300E, but AGX doesn't sound right. I think they were GR2's.

It sounds as if you are a penny pincher like I am. That's what made me buy the KYB's to start with. They were cheap. They are well built, but WAY too stiff for the 124.

I must say though, it's interesting when someone asks for advice, then gets actual first hand advice, THEN ignores the advice.

Maybe the harsh ride won't bother you as much as it bothered me. The harsh ride is only part of the equation. When the ride is too harsh, what comes along with that is too much dampening that prevents the tire from staying planted on the pavement better. When the tire is not consistently planted on the pavement, handling suffers.

I wish you the best of luck with them.
