Hi Folks, I haven't read anything on the forum about these shocks, so I'll post up a review for posterity.
Background: my early 2019 M3 SR+ rides like crap. The roads in my area are pretty bad and it just crashes and bounces over road imperfections. It feels like I'm driving a shifter cart on the street, lol. My goal in replacing the shocks was to smooth out and tame the harsh ride. My SR+ is basically just a commuting appliance, so something that rides like a stock honda or lexus would be my ideal situation. I've been thinking for a couple years about getting MPP Comfort coilovers, but could never quite bring myself to spend the money and after reading through the whole MPP thread, I wasn't sure if it would be the solution I was looking for. They have similar spring rate to stock and I did not want to lower the car at all.
Enter Tein. Tein EnduraPro are replacement shocks, while the EnduraPro Plus are adjustable versions. They are designed to work with your stock springs, but also should work with lowering springs. I come from a Japanese import background, so Tein is a familiar brand. Not top shelf suspension, but a decent reputation and products that focus more on street than track. What really drew me to the Teins was their use of an internal hydraulic bump stop. These allow much more uptravel than the stock shock/bumpstop combo and also greatly reduce the upset to the ride when you do engage the bumpstops. As we all know, the M3 basically rides on the bumpstops and uses them as a secondary spring, lol. I got the adjustable Pros for about $600 for all 4 shocks from a seller on Ebay. Here is some literature from Tein: TEIN.com: EnduraPro / EnduraPro PLUS - PRODUCTS
The shocks themselves are advertised as being "overbuilt" compared to stock and that appears to be true. The tube diameter is larger, the spring perch metal is thicker, the piston is thicker. All this should result in greater fluid capacity and maybe more durability than stock if you decide to take up rallycross. In the real world, thicker flanges aren't going to make any difference, but greater fluid capacity will. The front shocks also have about 1/8" longer piston stroke than stock.
