Check the cars tab and look at the saportline section.
You wills ee its not just springs, shocks and swaybars, it included new suspension bushing as well.
Overall it is a great upgrade to any 124 car.
Myself I went for aftermarket, I prefer stiffer than sportline has.
I would look into the full sportline upgrade, you wont be disappointed with it.
Talk to JCE about it, he did it to his car, and he can tell you the differences between before and after.
