The part number changed in July 2008 so I assume the newer version shock will last a bit longer |

I spoke to Jay at GC on Friday about our suspension and his comments were the same as Richard's orginal post. I have also decided to move on from the Moton setup and had planned to go back to stock but Jay convinced me to try their coilover conversion setup.
So what I'm going to end up with is stock EDC struts with shorter bump stops, stiffer springs (probably 430f/600r) to make up for the lack of OEM bumpstop/spring, camber plates, height adjusters and rear shock mounts for less than $1k. I decided to try this because I can set the ride height/corner balance the car, have a linear spring thus more control and adjust some of the stiffness via a button inside the car. I've had good experiences with GC in the past and am trusting Jay's experience in what he's recommending. I'll keep you guys posted on what transpires.... BC

How about brakes, how did those perform? Are you on stock brakes?

The stock brakes are fine other than the fact that the stock pads are junk, I warped 2 set of rotors because of them. Other than that, it never faded once on the 13 mile course and I usually do 2 to 3 consecutive laps. In hindsight, I should have invested in some Pagids. I am very easy on my tires and brakes, I did all 50 laps on the same set of PS2s. I had to replace the front tires after my last visit to the Ring, but the rears still had enough for me to do a couple of AutoX with a lot of drifting before I had to replace them. But as far as brakes, I'm going to get some RS19s before going to VIR this year.

I have Eibach Springs for My 2011 M3 so I bought the E36 Bump-stops and a set of OEM Guide Supports. I brought the OEM Guide-supports to the Machine Shop at Work and had the Machinist take 0.55" off of them.
With 0.25" shorter Bump-stops and 0.55" shorter Guide-supports (0.25"+0.55"=0.8") I now will have the full OEM suspension travel with my 0.8" lower Eibachs installed. |

I'm thinking that there's a risk that you may have added enough travel that the tire will now travel upwards far enough to hit the inside of the wheel well. Dinan would have done this exercise, and they only lowed the car about 0.4". If 0.8" is too far, some shims under the bump stop will make sure your tire doesn't contact the inside of the wheel well. I'll be very interested to hear how this goes - more travel is a good thing, and an extra 0.8" is a significant upside if it works. |

Also, my 2011 will have ZCP so I am going to compare part #'s of the ZCP parts to the non ZCP parts and see if there is any differences. There is a slim chance that the ZCP will have different bump-stops and/or guide-supports to make up for the 10mm of lowering compared to a non-ZCP M3. Finally, there is a possibility that I will like the stance of the ZCP suspension and I won't even install my Eibachs. |

I was at the Rolex 24 in Daytona two weekends ago and as I was eating dinner Steve Dinan himself sat down next to me. I had never met him, but he seemed like a great guy.
At any rate, when I told him I had an E90 M3, he started telling me about all the work they'd done on E9x suspension stuff that would be fully compatible with EDC. He was very proud of what they'd achieved in terms of handling while maintaining the comfort. I can't say I remember too many details, but I was impressed with his knowledge of the issues involved in aftermarket suspension tuning. He finished by saying even though he's known mostly for his engine tuning, he's also very proud of the work his company does on suspensions. After chatting with him for 20 minutes or so, I wouldn't hesitate to buy his systems if I was on the market for suspension components. Also, Im not sure, but I think their policy is provide warranty on the systems their components affect. Check with them for details. I don't have any first hand experience with the Dinan suspension, but I thought you'd all be interested in Steve Dinan's enthusiasm about his company's products. |

ok to recap
I have an e92 w/eibachs...I wasnt able to get the e36 bumpstops so my mechanic trimmed the oem ones...so far I have no issues and everything is great My mechanic is a suspension expert and stated that trimming the oem bumpstops wouldnt have any adverse affects Is he wrong and should I get the the e36 bumpstops and use those instead? thanks |

That is exactly what I want to do: 08 E92 M3, Eibachs, E36 bumpstops, +/- the shaved guide supports. Let us know. Subscribed!

I think I may go this way unless the GC setup is better setup. I think adding bumpstops and shaved guide supports is not shown to help and no one has shown any data analysis. I know that Eibach put a good chuck of development time into designing their springs to work with existing products.

Nurburgring Suspension
Don't get me wrong the stock suspension works great i did 25 laps on the stock suspension! But the H&R are night and day for my driving style. I prefer a stiffer ride plus the H&R got rid of the excess body roll on fast corners and fixed some of the slow speed plowing. I run EDC set to sport when dry & DSC off; when the ring is wet I run EDC set to normal and I turn all the electronic nannies on! The ring is freaking dangerous in the rain!

This is for armyav8tor and Trier Germany. I live about 1h 20min from the Nurburgring and I'm planning on tackling the course this spring/summer. I have been there before, including going on a joy ride with Sabine in her Porsche, but never driven the course myself.
What sound advice could you give me. Thanks...

I may just be dreaming. But I have a feeling the gc suspension is gonna surprise a lot of ppl. I have spoken with those guys, and they seem to know so much about this car its not even funny. As a matter of fact, I think someone there has one, or deff worked on one first hand.
