Yes.
I really wish Evan would chime in here because I don't understand why you would get different springs than me.
Maybe it's because you have an auto instead of a manual?
I don't know man!

Do you still have the ZSP front springs?
What part number is tagged on those?

Yes I have all of it at home. I will check when I get off work in about 2 hours.

I gotta say I am little frustrated. If it was advertised as getting the 1/2 inch drop with the kit, I feel a little left out. If a simple change in springs to the T3 will make this happen then i will be a happy camper.

If you have D7 springs up front and D4 in the rear like myself, AND if I really got the correct springs then it would make sense that you should have the T3 springs.
Of course, this is all assuming that there is a difference between the T3 and the T4. But why would they have different part numbers if they are the same?
Confusing!

There's a part of me that thinks that there's a difference with the transmissions.

No. Sorry.
I'm having surgery on Thursday so I need to work as much as I can this week.

I'll take pictures when I get the time.
so there is less wheel well gap in front than rear? sounds like what i'm looking for...a traditional rake

how long has the setup been installed now?

have you have the "opportunity" to see how it feels over rough pavement? or maybe crossing railroad tracks for example... the roads out here on long island this time of year due to the frost heaving and snow plowing turn to TOTAL garbage.

rough patch jobs and pot holes all over the place.

Looks real good! but isn't it kinda weird how according to your measurements that the driver front is lower than passenger front? I thought stock springs was the other way around for obvious reason?

I'm definitely very interested in trying these with my FSD but need to see pics of them on E92 first.

I just checked and my ZSP springs are D7 up front and D4 in back. This makes no sense why mine would be any different. The reason why I went with the new kit was because the springs were the same, witch would give me the rake affect in front. I will post pics of mine. could it be you have larger wheels and tire set up??

I think we need answers from Tischer and I'm not just saying this to start anything.
I just think it's fair that we understand what exactly is going on here.
IMO, it just doesn't seem right to me that you should get different part number performance springs than me if we both have the same part number ZSP springs.

It's also possible that Tischer made the correct decision with the ordering but BMW themselves screwed up.
I also know that the part numbers ordered are different than just the "T" numbers.

I completely agree. I am not trying to start trouble, I just want to know why. I know the big difference is I ordered the "new" kit and I dont think the other members have posted about their findings.

I cant be the only one with these springs. Lets twist his arm for the T7s!

Ok, I was just able to see the front springs, and the tag said T4. My biggest issue is with the rear, and I just cant see the stamp on the springs to know.

Fraggy, do you have an automatic? This seems to be why we are getting different springs. I feel like I need the T3s to match the rear but I could be wrong. How are your fronts sitting?

Yah man, this doesn't look right to me.
It's way different than the looks of mine.
Now, I know that I have 19s compared to your 18s but the difference is very close to nothing.
It's surprising to me that you can see so much of the spring.

f you jack the car up and get underneath with a flash light, I will garantee that you will see it stamped in grey on one of the springs.
