So I just picked up a '95 325is for DD. It's got 135K on it and the shocks are shot. I'd like to tighten it up a bit without getting crazy, so no springs...
I kinda like the idea of the proposed new Street Stock rules so i thought I'd go in that direction without...once again...getting in too deep.
I've done a little reading up, but I'd like to ask the Bimmer guys around here what might work best with stock springs.
Koni sports? Bilstein HD or Sports?
What about aftermarket sways? What's a good brand and should I update to the M3 endlinks?

Thanks for all opinions...

Don

Bilstein HDs are very durable. At least buy new springs for it. You should replace, FCAB, RTAB and ball joints. Check subframe bushings and the front lower control arms.

All the rubber and ball joints in the suspension needs replacing, I'll get to that bit by bit.
So either Koni Sports or Bilstein HD... would the Bil sports be too stiff with stock springs?
Any thoughts on sways?

I would get the Konis. The best sway bar setup would be the Ground Control kit, super light and easy to adjust.

I forgot about GC. The sways look nice, but are more than I want to spend. I might run the car once in a while, but not seriously.

be wary about upgrading rear sway; the tab mounts are weak even on m3 and need weld reinforcement [street touring legal]. a broken tab can mean $$$ subframe replacement

I'll keep that in mind. I won't be setting it up to ST rules, just (the new, possibly) Stock, and a mild setup at that. I just want it to conform to some sort of rule set, just in case...
After doing some more reading, I found that Bilstein HD is for stock springs, and the Sports are for short(er) springs, so I'll be getting the HDs, just 'cause they are cheaper than Konis... Laughing
I'll do more reading up on sways...

I really like the adjustability of the Ground Control swaybars, especially the front. I wouldn't go buying a pair of swaybars, yet. Lots of things up in the air...
