What's the difference b/w "old" BMW Performance Suspension kit and the "new" one?

If some one has the means to compress and measure the resistance of there springs then we can find out. I think it will take some help from folks on the forum to check what they got and tell the "T" number associated with their findings. They said that my vin says I need T2 front and T4 rear. I would assume that a larger number means it is a stronger/stiffer spring.

Quick question is there a "how to" for install of the performance kit and/or springs. It came with a lot of parts and I assume that I will find where everything goes. But I was also looking for tips and tricks. And I don't want to forget to put one of the new bushings in because I wasn't sure where it went till its too late. Bushing locations are really my concern here.

Can someone post a link.

I think tischer has an install pdf. While it does not show how things fit together, it does list all the parts and what they are along with general install steps. *** Edit, attached it for you to view.

Since my e90 LCI is manual 328i so I should run D4 springs all around, what about if I run D5 front and D4 rear from the auto zsp spring??? Make any different?

Just get the correct springs. Ride height will also be taller if the spring rate is greater with D5 vs D4.

They come up now and then. I got mine used from the classifieds for around $100. I have the rear D4 springs that I didn't use from my set since I have a wagon but that doesn't help you much :)
