| The assembled Soft mount in place on the crossmember |
 |
| For our car we decided to use the hard Motorsports mount instead. It is a full hard urethane replacement bushing. It is a high quality part with a steel sleeve and must be pressed in place meaning that the diff carrier has to be removed from the car. A lot more work. We didn’t mind the extra work so we went for the harder part. |
 |
| These bushings replace the rear diff carrier bushings or the mustache bar bushings as they are known. The bushings on our car were ripped and totally failed which probably contributed to the horrible clunking noise coming out of the back. |

| You can see the poor condition of the stock bushings. |

I have a 2004 STi. Can the hubs and steering rack be just direct replaced with an 05 sti?
I was looking into following your project fairly closely with my car but wanted to make sure I address any issues native to the 04 to make the path easier.
Are the engine management quirks mostly addressed once the car is tuned with something like a COBB accessport?
The hubs can be but the rack cannot. However, Whiteline makes rack bushings that work well for these cars. The Access port has been pretty dialed back but is fine for OTS tunes and for strictly following Cobbs Green Initiative upgrade paths. For maintaining smog legality this is really the best way to go. For more advanced stuff ECUtek is the way to go.
