I just dug out the old Tischer Performance Shock Kit I ordered over a year ago...The part number is #33500429574

I'm ready to install them now, but not too sure what springs to pair them up with. I have a 2008 328i non-sport E90 sedan with manual transmission.

Has anyone paired these shocks up with non-oem springs (Eibach, H&R, etc)?

If I wanted to go 100% OEM, I keep seeing references to D4, D5, D6 springs? Which springs are for which car?

Thanks guys!

I run the stock sport springs with mine.

get either a set of sport springs from a car similar to yours that has the ZSP option (to have the Dx you need), or go aftermarket (I wouldn't recommend eibachs), or if you can source a set of BMW perf springs from the v2 kit you will be amazed - that was I have and feel it's a really great match.

If you want to keep it OEM, stick with ZSP springs, otherwise EPK springs (which have a similar spring rate to the ZSP springs albeit slighty stiffer) are the recommended springs with these shocks. I paired mine with EPK springs because I wanted a lower stance.

[lowgman]

Hmm... Sounds like the EPK would be my preferred route. Do you guys have part numbers for those particular springs? Thanks!

pretty sure you would need shorter bump stops if you are using lowering springs or else you may be riding on your bump stops at times.

I'm pretty sure the PS struts come with shorter bumpstops.

He said he bought the v1 kit. The bump stops are designed for sport springs. Lowering springs would require shorter bump stops. The V2 kit has different springs and different bump stops.

On ZSP -- have installed the rears and still debating on diy installation on the fronts.
.
Car has 70k miles --- so far the new rear struts really firmed up the ride but a little bouncy over bridges / expansion hwy joints.

.
Kit has all the bstops / sleeves and fasteners needed to do the job right.

Nope. OP has the 'old' V1 kit that came with taller, firmer bumpstops designed to be used with oe sport springs.

Ok, thanks for the correction, I was under the impression the bumpstops were shorter even on the old V1 kit.

I also have box o' parts in the garage. So really no ride height change if I install the v1 kit on a '07 e90 with sport package? Maybe slightly firmer ride?

At 65k the car is getting sloppy on original shock/struts.

no ride height adjustment from sport package.

I'd say more than slightly firmer, maybe "definitely firmer" though very tolerable for daily driving. I think you will like the change with the V1 kit, especially if you're sport shocks are worn.

Thanks.

I had 'newer' Bilstein Sports on my previous 95 M3 and loved and lived with the firm ride.

just my 2 cents..not bashing the BMW Performance shocks...I actually had them on my E90 with H&R Sport springs......I would use them only with the factory OE springs wether sport or non sport springs its a good upgrade.

The rebound is extremely unpleasant. Save and buy the Koni's since Bilstein no longer sells the SPORT shock, but can be aquird by special order only.

I have a set its was on my car for 1 week.....im giving it away, I would be ashamed to sell it to someone...let me know if anyone wants its, Im in Fairfax VA.

Dude - send them to me ! I need a spare. With the yellow springs they are the best setup I've experienced, lightyears away from ones I had before: ZSP on the e92 / Bilsteins sports + H&R on my Golf / Bilsteins sports + Neuspeed on my Passat. The way I see it: either your shocks are gone or there's something with your car...

I'm about to get pro kit with my old performance dampers. I think it's a little too bouncy especially with 3 others. And I would like to lower it to about 1 index finger width height.
