Any folks wanting diff gear changes? I want to upgrade s54 M roadster to 3.46 or 3.64 so I can use the high end more effectively. If I can find 2 other folks who want to change diff's we can all save 15%. Prices are around !700 to 1900 depending on gears, model etc. These are limited slip(40%) and quaife units are also available with any gearing. email me if interested-yogajohn@mcn.org

Sounds kinda expensive. Check out http://www.vacmotorsports.com their quaife units are $1250. If you can setup a group buy on those puppies with a discount then I'd be interested.
