Hi, My name is Steve and I am an addict, of BMW's. I will be parting ways with one of my 89 325I's. I noticed the sway bars are different diameters. RealOEM lists the 84 as 18.5mm and the 89 as 20mm. Is it worth it swapping before I sell the 89? I will be running H&R Sports with Bilstien Sports on the 84.
