Hello and Happy New Year,

During our G50 sale last month I got more than a few PMs/Emails asking me when there would be a special for the Cayman and Boxster owners. Your requests have not fallen on deaf ears and here you go. For the month of January we are offering the following differentials on sale:

987S Pro-LSD. This is our top of the line product for the 987 S 6spd gearbox. This is not for the 5spd, tiptronic or PDK. It is a 4 plate differential with the ability to set it up as a 65/45 or 80/50 locking configuration. It features a billet chromoly body for bulletproof strength and long lasting durability. Regular price on it is $2695. Sale Price is $2195

987S Torque Biasing Differential. This is for the auto crossers and guys just looking for a little extra something on the street. It's also the only differential that's been certified in several classes of racing that currently are not allowing a true LSD in the cars. I'm not going to pretend that it will give you the same performance on the track that a true LSD will provide you, but as long as it's the only thing the rulemakers allow it's better than an open differential by a long shot. Again, this is for the 6 speed cars and not the 5spd, tiptronic of PDK gearboxes. Regular price on it is $1795. Sale Price is $1495.

This sale will run through the month of January. Please be sure to get in touch with us early if you need it on a particular timeline. Our offices will be closed the whole first week of February while we are at Daytona and Sebring so last minute orders placed Jan 28th and 29th won't ship until Feb. 8th or 9th. And specialist installation is advised. Talk to your mechanic prior to ordering these parts and make sure they've got the experience to set this up properly. Many shops don't do regular gearbox work and if you need guidance on who can put one of these in for you, please don't hesitate to ask.

Kind Regards,
