Titan Motorsports. They're originally for the MKIV Supra but Titan was able to slightly modify it to work on the 2IS differential housing. Figs offers their own high durometer differential bushings which are a direct fit.

Yes, Lance is correct. Here's a shot of the Titan Motorsports Solid Differential Ear Mount installed on my car that I was referencing earlier:



I ended up having some free time tonight so I decided to jack up the car and install the new Rear Subframe Suspension Braces:

1) So shiny and pretty


2) Here's the beefier subframe brace installed on the vehicle. The OEM brace feels thinner and flimsier than this new set. You can also see the Titan Motorsports Rear Differential Solid Ear Mount to the right.

Nice! Easy install huh!? I noticed something today when I went to my mother inlaws, parking in her steep driveway usually turning to park from the street/ going up over the sidewalk/ driveway transition would really flex the chassis and would be frightening but it was a tremendous difference with the new braces. I can take a pic of her driveway some time so you get a better reference lol

They are more rigid than the stamped steel oem, wether you can tell the difference in performance is rather unlikely. Still a good buy, the guy is nice/trust worthy.

are these the same bushings you're referring to from FIGs: http://shopfigs.com/v1/index.php?rou...product_id=236

First time I hear about these, has anyone documented this install or product?

Yep! I used some chisels n punches to drive them out. I tried a bushing tool but the center just flexed too much and the metal cup has to be removed

The braces are pretty much a knockoff of some we designed back in 2005. I decided not to market them, because I do not believe they are effective on such a small mount and since the subframe bushings are like jelly, so why reinforce them.

I will try to get a video of the subframe. IMO its just adding weight and removing aero on the F. I will be making semi solid subframe bushings shortly as now that our car has serious grip, the mounts are the largest source of instability in the rear.

^I've been hearing rumors of soft subframe bushings ever since I became interested in the 2IS platform. I know when I did some suspension work a year or so ago I noticed how big and soft they were. Looking forward to the video, and your solution.

In BMW world the regular 3 series has soft bushings and the M3 has stiffer bushings, a very common upgrade for the regular 3 series is a set of M3 sub frame bushings.

Yup, those are the FIGS rear diff bushings that I was referencing earlier.
