Rear suspesion components

OK, looks like I'm going to be starting on fixing my subframe some time in the next few weeks. Check here for more details. Since everything is going to be off the back of the car, any ideas what else to upgrade? I'm already having the Turner reinforcement kit welded in when I get it all fixed. I am also planning on getting coilovers (Ground Control) to replace my H&R springs and Koni shocks.

While I still intend to drive the car on the street a fair amout, it is increasingly moving to a weekend driver only and not a daily driver. I don't want it set up as a full on track car, but I do think this is the time to upgrade.

Rsm

There are many rear shock tower mounts and reinforcers on the web. For track cars that have removable adjustable shocks get a RSM with downward bolts so that you don't need to open the trunk and rip out carpet every time you adjust/replace shocks. If you want the car streetable I would stick with the rubber style and not the metal (spherical). Rogue and JT Design look like they have nice ones. Call JT Design if you don't see what you want, for some reason they don't have everything on their web site. I think that GC has some too.

I ended up going with the subframe, sway bar and shock tower reinforcement kits from Turner. I am replacing the subframe and differenetial bushings with stock BMW bushings. I am also getting the trailing arm reinforcement kit and a set of Ground Control coilovers (which come with upgraded shock tower mounts).

I'm looking forward to trying them on the track in the spring. I don't track nearly as much as you do and it is way more suspension then I know what to do with, but it should still be nice.

i just installed a TC Kline Single Adjustable setup and am waiting to get the damn car aligned so I can really ring it out. I also picked up some rsm reinforcement plates from BMW....originally for the Z3 1.9l, it slides over the top of the shock mounts (access fromt the trunk) and then bolted down....also wise to pick up the paper gaskets so theres no metal on metal rubbing. Cost me 17 bucks. Id like to find out more about the trailing arm bushing reinforcement kit you guys mentioned though...any info? Trailing arm mounts rip out of e36s like they were designed that way...to break...my friends all have theirs welded and re-welded to reinforce them...wondering if i should do the same. I have 50,000 hard nyc miles and just installed this suspension....I hope my car holds together.

I bought these used ones but it looks like they have another set.

These bolt onto each side of the inside of the RTAB cassete. It makes it so the RTAB cant flex as much and keep toe in/out more consistent.

sweeet...i actually just ordered a pair of these from motor-force.com. The ones i got are a little bit cheaper....$40 bucks but they look like a hard plastic, not metal. It took 4 weeks to get them though. I would not reccommend doing business with motorforce...they don't respond to emails and have no phone number listed anywhere. Im going to install them tomorrow.....hope it all works out well.

Probably delrin ones. I dont beleive those screw onto the cassete so it should be much quicker to do.

are you having any noise issues with these?? i'm debating between these and the GC delrin ones. i'd go for the ones above if i can be assured that there will not be any noise issues.

No noise yet but I've only had them on for about 3 weeks. I also put some grease inbetween the bushing and the aluminum plate.

You're right, they are the Delrin ones. Installation was a snap. They fit well, no noise and they eliminate some of the lateral movement in the rear by eliminating the bushings' built in play. So far so good, but I haven't had a chance to really rip on the car with all the snow we got here in NY.....
