ATI has designed a damper for the MINI Cooper S engine. This new design is a direct replacement for the stock OEM MINI Cooper S damper from 2002 through 2006. So when the OEM early design rips, or the late design comes apart, this is the one to get. The heart of this unit is the tried and true damper within a damper design that has put ATI ahead of the rest. The outer shell has been specially machined to allow the OEM serpentine belt, and includes laser-etched timing marks (even tho it does our MINI's no good). Available in stock size (0%) or very popular 2% oversize. The 2% will function just like stock, but give you a bit more boost, which in turn makes your car faster! No modification to the ECU is needed. ATI gives you an install tool, but you will need a tool to remove your stock damper. We rent or sell the tools you need. MINI also says to replace your crank bolt, we recommend it. We also see a lot of crank seal leaks, so we highly recomend replacing this seal at the same time.
You might want to also upgrade your damper bolts to the light weight titanimum bolts!

I purchased the ATI 2% overdrive damper, crank seal and crank bolt from the fine people at Detroit Tuned, and received it in 2 days. Installation was easy, and took a bit over an hour. I highly recommend the specific puller to get the factory part off, especially if it was in two pieces like mine. And the MINI has a noticeable gain in power at around 3k and up. The ATI is rock solid and Detroit Tuned delivered again! Whenever possible, I will be purchasing everything from Detroit Tuned, customer service is excellent and Chad is always responsive to technical emails.
