Just get a qualified engineer to install it is all what matters bud. STATS don't lie, quality readers should feel this (naturally!)

These bearings are good for 500,000miles (if you rely on spec sheets)

Mind you a lot can go wrong with your (and my) crappy little M96 lolll

I rin the IMS Gaurdian on a dual row Boxster. I bought the car with less than 80000 on a clutch that had been replaced once. I have the position that if the bearing fails before the next clutch job, it will be dealt with at that point. If the lasts until the next clutch job, I will replace the bering with the IMS at that point. If I am so inclined at the clutch job, I will also consider sending the entire car to Jake Raby to have the Stage 1 setup installed. Intending to to essentially have the engine prepped for wat I would hope to be prep for another 100k of service prep completed. I fully expect to be installing new tops, suspension, hoses, water pumps etc going. I want to keep the car going until the paint wears out.

With 100,000 miles you are WAY past the time to ONLY worry about the IMS. With that amount of mileage, there are numerous other components that are just as likely (or maybe more so) to fail - are you going to do anything about those? If not, then just keep driving it, change the oil often, and when it blows replace it. Start saving for a rebuild or replacement now.

For the record, my engine blew at 136,000 miles with 89 track days due to valve lifter failure. I suppose that I should have installed the Valve Lifter Retrofit. Just joking, that doesn't exist and neither does the Timing Chain Sentinel or Carbide Chain Tensioner Guides, but I'm sure you get the point. Oh, and when the engine was torn down for rebuild, the original IMS bearing was in great shape. Your mileage may vary.
