This makes any comparisons reach a false conclusion. Here is an illustration of what I am referring to, along with a picture of a special GC assembly of increased travel. You do have to be careful, and the 11mm is about the limit for the EDC motor vs. negative camber vs. stress bar bracket. Last edited by JM3; 02-09-2012 at 01:12 PM.. |

^ Thanks for chiming in Jay. what exactly are you showing there?
There is just a flat washer, and it's about 1/8" thick. I don't see what else is there? Your picture implies that the curved washer's entire thickness is part of the stack height and it's not. |

I trying to show that when comparing apples to apples, that GC and stock are equal "stack height" and equal suspension travel.

travel. "Stack height" is a contrived term, and can be very confusing, if not downright misleading. The pic I attached we are trying to show "stack height" as being 29mm across the board, while the crucial "block height" can vary, and is actually the TRUE indicator of available suspension travel. I only heard about this thread via some emails asking questions that didn't make sense to me, so I hope this explains to the guys who emailed me. Last edited by JM3; 02-09-2012 at 03:29 PM.. |

Dinan claims an increase in suspension travel by shaving the bottom of the OEM mount. So would the plate in the middle provide a similar amount of suspension travel gain that Dinan claims?
In my mind, that would be ideal for the Dinan suspensions that will see track and street use. Am I on the right track?

Here are the parts off my car:
31332283379 is the smaller washer 31332283038 is the larger one on the bottom. It's nowhere near as thick as the one in your photo. was it a production change? Last edited by kitw; 02-09-2012 at 06:33 PM.. |

That is a race plate and will transmit more NVH than the shaved Dinan parts, and will not work with stock diameter springs. (It's actually more than what Dinan gives, they shave the top hats by 6.35mm.) |

So will the normal GC plate with the Dinan setup work.

It's my understanding that the middle plate is a modified version of their street plates that will fit stock springs. It just has a different overall height from the regular street version. Correct me if I'm wrong, Jay.

Thanks for chiming in! I'll take a little extra NVH in this case...a fair trade off.

The thin washer is the TOP washer. The thick one in my pic, and hidden in the pic you posted, is the lower washer and I have not seen or heard of any changes. In fact it is the same washer as used on early e34 M5, and very early e36 four doors, so it has been around a while and probably wont be changed Last edited by JM3; 02-10-2012 at 10:37 AM.. |

"Modified" is perhaps even too strong of a word, because it is just assembled differently with existing modular parts from a modular system of STREET camber/caster plates. The RACE camber/caster plates are even thinner than that pic, but cannot accommodate stock diameter springs, and the EDC motor can get too far upward. Thanks.

(I machined a set of stock mounts down by 8mm with no issues at all, btw) What is the middle plate and does it have the same kind of not-completely solid mounting as the street plate? |

That is the street plate, just different configuration. I have already ordered another 31332283038 and a 31332283379 , just to see what I get. It will take a few days.

I just ordered my GC plates to go with my KW springs. Thanks Jay!!
Had i known i would have just done the GC kit with springs and plates but I didn't think I'd need the plates right away. Unfortunately for me i can't get enough camber out of the driver side now to match the passenger's. Gonna take it in on Saturday and get them installed and aligned. I think the shop who installed the springs last week messed up my headlight arms because my headlights are all outta whack now. Worst thing about Nashville is the lack of good shops. I have a good body shop and there are some decent indy shops but no one stop shop. My indy bimmer shop doesn't have an alignment rack so I have to hit a standard Firestone and walk the guy through my alignment. |

For those interested, I just ordered the shorter GC plate to go with my Dinan stage 1 suspension. I's planned to go in next week. I'm no expert in suspension but my local shop confirmed that it should work fine.
If I get this whole thing correctly my 2 choices were: A) Get Dinan camber plate This would raise the front by 1/4" which I'm not excited as I find it a bit too high already and the amount of camber you can get is limited. In my case, I could only get -1.4 with the pin pulls so probably ~-2.1 with Dinan plate B) Get GC plates (modified shorter one) This gives me all the camber I want or may want in the future, increase the suspension travel on top of what I already have with Dinan and doesn't increase the ride height like the Dinan plates would. That sounds to good to be true, what did I miss??? Someone said something to the effect that the EDC strut could have a problem with too much increase in suspension travel. Could I switch back to my OEM bumpstop (from the Dinan E36 one) if this a problem to reduce the suspension travel? Here is a version of the side-by-side comparison that I modified to what made sense to me. Anyone care to comment if I got this right or am I totally off? If the install is successful, I'm taking this to the track next Friday. |
