Solid Everthing

[PC Racing]

I'm making this post to share the suspension upgrades I'm doing. I'm aware there have been posts on other fourms about this but I haven't seen any about soilid and spherical set ups.

Parts list for the rear:
Akg end links
Ecs sway bar
Akg sphirical lower strut mount
Akg poly upper strut mont
Godspeed toe/upper control arms (spherical)
Polly lower inner
Rouge engineering lower outer (bearing)
Rouge engineering trailing arm bushings (bearing)
Ecs trailing arms
Tuner solid subframe bushings
Turner solid diff bushings
650i finned rear diff

Front parts list:
M3 control arms
Akg spherical inner uppper
Akg spherical inner lower
Akg end links
Ecs sway bar

At this point I have the rear end down and disassembled but I will keep this post updated.

Nice

All those well manufactured parts and then...Godspeed arms??

Are those bearings covered with a boot or just exposed on those arms? Heard way way too much about premature failure on those Godspeed bearings

 

[PC Racing]

One of the arms has a boot the others are open. I have friends running there toe arms for over a year with no issues. If they start to fail I'll upgrade at that point.

I'm just pretending right now for the sake of my wallet and sanity that there are no suspension upgrades beyond coilovers.

Nice!! I'm running a good amount of those parts too. The GSP arms have been great for me. I'd like to add the 650i diff cover myself. You have to make a spacer right?

Yes you need to make a spacer. I bought a 3 foot long aluminum stock and plan to make a bunch of them for other people who want to do the same.

Nice, I have a machineshop so it would probably be pretty easy to make.

Small update of today's progress. I got all the bushings out of the subframe and made a tool to remove the diff from the driveshaft. I have one that was made for the job but it was a few mm to large. On that note if anyone needs any of these tools I'd be happy to rent them out.

Need to get some bigger drill rod to press the diff and sub bushings but got a few things done today.

hm, if you're going that far I feel like you should have swapped an M3 subframe in as well

Far as I know the subframe itself is the same. I could be wrong though.

Is it? Also, would be nice to have some kind of repository of of CAD/CNC Program/Drawings for custom tools for things like this, along with the fuel pump removal tool and a few other things.

I want to get into 3D printing and possibly hobbyist milling, so this has been on my mind.

It is different

 

[PC Racing]

It is different

I know the part number is different since it has better bushings. What's different about it other than that?

Edit
Yea, your right it appears the rear diff mount is different. I guess that would be nice if I didn't already have an lsd for the 135i diff.

 

[PC Racing]

New diff cover fits well

 

[Danksies]

Interested to see what difference this makes. I'm guessing you weren't on stock suspension before this so what did you have before this install?

Befor the instal I had ast coil overs and m3 subframe bushings with a wavetrack lsd.

Got some things done today. The diff spacer was simple to make since the rear diff mount from Turner moves. The meant the size just had to be within a few mm. I did have to get a larger bolt for the rear diff as the stock one was short buy about half an inch.

So, I assume you're a 6MT, and you have the 215mm differential? Also is this the correct cover?

I'm interested in this but I have the small AT diff.

That is the correct cover however it's my understanding that the 650i cover will only fit the large diff, my car is mt.
