I'm using these trailing arms to do the necessary modifications to get everything lined up while they are sitting on my work bench. This way I don't have to take my car off the road while I figure out this mod out. Once I get things worked out I'll either just install these trailing arms or (worst case if they won't fit) transfer the hardware over to the ti arms.
The reason I can see the that the Z3 arms will work on the ti:
- The Z3 1.8\1.9 subframe is interchangeable with the ti (same part numbers for those members, P/N 33321091151 trailing arms and P/N 33311090957 rear axle carrier).
- The same Z3 rear axle carrier that is used on the ti (P/N 33311090957) is used in all Z3 models 1.8 to the 3.0i.
Therefore, unless the body of the 6 cylinder Z3 is different than the 4 cylinder, (which it could be, but I don't think it is) the Z3 arms should fit the ti no problem.
The 6 cylinder Z3 arms are strengthened a little since they have some additional bracing that the 4 cylinder ti doesn't have as well as larger rear wheel bearings (just like the 323ti). | Based on experiences from another guy that did a complete rebuild of his e30, the trailing arms from the 4 cylinder Z3, Z3M and Compact can be used on an e30 without altering the geometry. The trailing arms from the 6 cylinder Z3 is approx 50-60mm wider and can't be used on the e30, due to erronous geometry (he learned it the hard way...). In my understanding this means that the trailing arms from the 6 cylinder Z3 can't be used on the 'ti. | | | | | 01-10-2010, 12:49 AM | #168 | | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 |
Using stock ti spindles, ive found that E46 330i rear brakes can be used but require custom shoes. *shrugs* __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Do you have any pics of this set-up that you came up with? What are you using for caliper carriers? Are you using 330i rotors and calipers too? __________________ Alpine Weiß 1995 318ti

Im replicating it from a job an e30 guy did.
Everything is OEM 330i rear, calipers, carrier, rotors, pads. The carriers bolted up, required a slight milling of the upper hole of the carrier, disc on, caliper and pads on, shoes were off by a few MMs. To do the shoes, he just used the ti brackets, removed the abrasive side of the ti shoe, then welded the 330 shoes to the ti shoe/bracket. Bolted right in. __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Bolted right in. | The overall height of the 320x22mm 330i rear disc is 60.5mm. This is equal to the height of the 276x19mm e36 328i discs unsuccessfully tried fitted in the very beginning of this thread. The overall height of the rear ti'-disc is 78.1mm. I.e. that the ti's brake shield and shoe has to be moved 17.6mm outwards in order to align properly using the 330i rear disc. In my experience, the use of carriers from other BMW's used on the ti requires making an adapter. If there is pictures of this 330i application, it would have been very much appreciated. Another issue is the brake bias since the piston diameter of the 330i rear caliper is 42mm. | | | | | 01-20-2010, 10:53 PM | #172 | | Senior Member Join Date: Oct 2006 Location: Europe Posts: 224 | Update Jan 2010

Some ideas are tested. To be sure that the carrier can keep up with the load and stress, the design is fed into a FEM-tool where stress and load simulations are done. The load was determined by analyzing and modeling the complete brake system. Here is an image of the first iteration of the carrier design:  I am feeling very lucky to have knowledgeable friends that are willing to help doing the FEM analysis. This is fun...

This is as expected, and is easily seen by comparing the brake disk data. It is of course doable, but I am not convinced that it is plug and play on the 'ti ... ... not to forget the issue regarding the brake bias since the piston diameter of the 330i rear caliper is 42mm. | | | | | 02-03-2010, 03:54 PM | #177 | | Senior Member Join Date: Apr 2009 Location: Merritt Island, FL Posts: 351 |

He says in post 10 up front that he is using Z3 suspension (I'm assuming that includes trailing arms also). Now I'm not sure how he got the 330 rotors to just fit up like that, I think there is some information that he doesn't include there. Without researching, I would think that there was an offset difference between the drum on the z3 rotors and that of the 330i rotors. He is probably not using the Z3 hub flanges since they have the same offset (or height) as the ti flanges. My guess is that his trailing arms are a hybrid using the Z3 arms\bearings and hub flanges out of an e36 sedan or coupe. I say this since the offset of the coupe or sedan (from the pictures) looks similar offset to the 330 with the same lug pattern. He also doesn't say exactly what he did to the caliper carrier either.  I'm not 100% why he just ground down the one ear of the carrier like that. He is probably using a spacer\adapter in there of some sort. __________________ Alpine Weiß 1995 318ti

these guys do all sorts of big brake kits, including for 318ti and z3, albeit at a high cost. also they use willwood calipers, which are not my fave. http://www.massivebrakes.com/home/ | | | | | 02-12-2010, 04:10 PM | #179 | | Senior Member Join Date: May 2006 Location: 43609 Posts: 3,425 |
You guys must have just skimmed over the pics rather than actually reading. He posts what he did to get the rear to fit. Quote: | Tomorrow I start the big break kit.. 330i front and rear breaks on my E30. I have the Z3 2.8 5lug swap under the car. I pulled the z3 hubs and wheel bearings from the rear and replaced them with e36 325i hubs and bearings. this will allow for the correct offset from my wheels and for the brakes to work properly... | __________________ 1995 Hellrot Clubsport 318ti -Gone 1996 Schwartz II Sport 357ti - 5.7L V8 LS1/6 1997 Moregrun Metallic 318ti - Gone

Thing about those hubs is that the TI uses smaller bearings, where as e30, e36 and e46 (except the big engine ones) use same bigger bearings, so the hub is interchangeable (between the e30 and other models, as in the case of the guy swapping 330 rears). But will the larger diameter hub fit over the smaller TI bearing? Or do you have to swap the rear bearing as well as axle to be able to install the shorter hub? | | | | | |
