How much of a drop from M3 Springs?

[Spencer]

Correct me if I'm wrong, but M3s use the same shocks as any other 3 series short of the '84 318i.

No, they were stiffer. And I blew my stock shocks in 2 weeks with M3 springs.

crap - now I don't want to put mine on.

I think it depends on how you ride on them, if you don't do any auto-x or anything like that, and it's just like city driving, I don't think it would be that harsh as to blow in 2 weeks.

Mine was city driving (on nice roads) about 10 miles a day.

Ah, fer fuks sake... how many km were on the M3 springs when you bought them?

Are you 100% certain that your shocks aren't blown right now? Stock Boges don't last that long.

Son of a bitch! If stock Boges will blow, what other ones could I buy that won't blow and that aren't as expensive as Bilstein sports? The OEMs I'd be buying would be new. New shocks gone in 2 weeks is horrible.

I'm getting M3 springs btw.

60,000-70,000 miles.

Really doesn't matter how many miles were on the springs... its how many miles are on your shocks. A shock will start wearing out and loosing damping, causing the suspension to bounce more and more after each bump. Eventually they'll just blow (leak) completely. Throwing on shorter/stiffer springs compounds the situation.

A spring doesn't really "wear out" per se. After time, it may loose its spring rate some or sag, but it still functions as a spring. A blown shock is pretty much worthless.

IMO, you get what you pay for in shocks, especially on a modified suspension. Stock pieces, or their OEM equivalents, are really cost-driven items. OEM shocks tend to wear quickly, and probably have wide production tolerances.

How do you test this?

When I push down on any corner of my car it pops back up to normal height without any drama. It doesn't bob up and down at all. I think this means they are good right?

It's really tough to tell sometimes with stock shocks and springs...

Here's what I would do:
Jack the rear end of the car up so that the wheels are off of the ground.
Unscrew the two nuts on the RSM off.
Then see if you can compress the shock down by hand... if you can easily and it stays where you compressed it to then it's blown.

Good to know.

Thanks!
