LOL....I was just playin' I hope to have 4200's on my E30 M3 this Fall and I'm sure they will be awesome. I have not doubt 4100's are great (lots of E30 guys running them and are very happy), but it's nice to have the adjustability. I like the modular design of the 5000 series. Sure made it nice to upgrade from 5200's to 5300's with a small amount of cash!
You going to do AST's when you sell the KW's?
