Can Koni STR.T Struts/Shocks handle lowering springs?

Hi everyone,
I've been looking to lower my car for a while now, and I have some cash to spend on it now, albeit not THAT much. I was wondering, could the Orange Koni's handle lowering springs, such as H&R sport? The struts/shocks are listed as "Entry level Performace", but how do they compare to oem. The price scares me, I'm riding on OEM springs atm, with new Koni Struts on the front (about 500 miles on em). I can get matching shocks for the back for about $150, coupled with $200 for the springs.

http://www.ecstuning.com/BMW-E46-330...cks/ES1866465/

My questions:
Could the suspension system handle these lowered/firmer springs? If so, for about how long (estimate)?

Will I need any additional parts to make this work? I'm currently running with a 325ci with a Factory Sport Suspension (minus the two new Koni Struts)?

Yes they will handle lowering springs fine.

I have them with H&R Sports.

They run similar to the soft setting on Koni adjustables which is still stiffer than stock.

Why are you buying just 2 shocks?

^ +1, running them with H&R sports as well.

If you read more about them on Tirerack:

"KONI has drawn on decades of high performance shock experience to develop an affordable, performance shock absorber. A great O.E. replacement that offers additional stability, control and handling without a harsh ride, the STR.T (pronounced "street") Shock also nicely complements lowering springs and/or anti-roll bar upgrades."

Also, Tirerack has them on sale right now (cheaper than ECS) $264 before shippin (for all four) or $68 for the rear shocks.

http://www.tirerack.com/suspension/s...4&autoModClar=

You will likely need to replace the shock mounts too. When I had mine done, the back looked good (which isn't normal, the rears are known to wear out) but the fronts were shot and thus replaced.

Ofcourse, don't forget you'll need an allignment done after you lower it. All in all I paid $1,246 for springs, shocks and front shock mounts, install and allignment....so don't think your going to get it all done for $300 or so.

Thanks for all the insight. I have a friend who works as a certified mechanic for a luxury dealership, and he can do the install for $120-180 on his own time. I just bought the front two struts (The Koni STR.Ts) since my factory ones had worn out about a month ago. So'll prob need the two rear shocks which are $68 each on TireRack I believe, plus mounts, which should run $20-30 each. So I guess I'm running at about $220 for the shocks and mounts, plus another $220 or so for springs, or hopefully cheaper if I can find someone selling them on here through classifieds. So I'm looking at close to $600 after install.

Jmanscotch, your car looks great! Same year, same model, same color! I've also used vinyl to make the trim matte black and I also have a lip spoiler hahah! I'll probably getting some sort of black wheels though, right now I'm running stock chrome 119's. Are the wheels in your signature 18s or 19s? They look great coupled with your suspension set-up, pretty much exactly what I'm aiming for. Although I will most likely opt for 17s or 18s for my wheels.

$600 would be a nice deal.

Thanks! Wheels are:

Front 19x8.5 ET 35 with 235/35 19s
Rear 19x9.5 ET 35 with 265/30 19s

The rears are rubbing pretty bad, when I make even light turns or even just give it some throttle and the rear squats down some...hopefully a fender roll with work for me or else I'll have to pick up some 255s for the rear.

I think 18's would be a lot better than 17's when lowered.

Here are a few more shots to show the setup:

IMG_0111

Not a great picture at all, but it is the only one I have that shows mine lowered yet still on 17's...may help you when contemplating wheel size.

Can people with 330ci sport package suspension on coupes comment on how well the str.t's looked when changing all four corners? I've read 2 separate reviews now that state that they've put these str.t's on and it's raised the car like a few inches - like the strut was much longer than the standard 330ci sport!
I want to buy, but now seen 2 reviews saying they don't work well with stock sport sus???

Thanks all,
Dan
