I done the exact same as you fella LOL
I had 17's on for about 1yr 1/2 and could'nt understand what the comotion was about when everyone was saying the E30 was great at handling........i thought it was crap!
Got BBS's, refurbed and chucked them on and i did the same as yourself and could'nt beleive how much fun i had missed out on, i even considered selling the car!
I've now got Koni adjustable shock's all round (Courtesy of Dan-318is

) and also have changed the spring's to H&R -60mm -40mm (Courtesy of bigdek

) and what a difference. I can throw it so hard into a bend and it just stick's
Plus i've stuck on some new Kumho boot's to compliment everything else and i am very impressed
Word of advise, put 28 psi all round and you will get the best and full effect of having the BBS's on
Next bit to go on are the ARB's with polybushes
