Last night I worked a trade and now own a pair of rear yellow Bilstein shocks. I believe they are " sports " and there is a sticker that says they are # B46 179. So what do I have here? They have the adjustable clips that adjust height but nothing else like springs,perches or mounting hardware. My thoughts are to buy threaded collars and springs so I really would have adjustability for height. Any suggestions on who to purchase the collars and springs from? I currently have Konis on the car with 140 lb. springs but my car isn't running yet so I don't know how good that setup is. Car will be street driver but leaning towards autocross / DE weapon. And is it true that most aftermarket springs that fit the adjustable collars are smaller in diameter than OEM or the springs I have on the Konis? Feedback from the experts is appreciated.

You can get them from this guy

If you want to go all Koni ( and sell me the Bilsteins )
Lavanaut has these 185# Koni Springs that were on a koni setup

And finally yes some springs are smaller but the Weltmeister springs should be the same diameter.. I honestly don't know on the Koni springs.

You need a specific Lower collar that fits over the shock body of the Bils then you can run any of the various springs of OE dimensions. The top mount is just the stock setup. Your correct that when you switch to the coleman style perchs they require a smaller diameter spring.


BTW go here for those Lower perches
