IMS retrofit vs. IMS solution?

[wrs986]

I have a 1999 Boxster with 40K I recently purchased. I want it to last and with everything I’ve read on the internet there are just no guarantees if your IMS bearing will fail or not. I found a shop that will install one at a reasonable price. I’m trying to educate myself on the different ones available. It looks like most install the LN Engineering bearings. Is the biggest difference between the IMS retrofit and IMS solution price and longevity? It looks like the retrofit is good for 75K and the solution is lifetime with about a $1000 difference in price. I don’t plan to track the car. Just a Sunday driver. Are there any statistics on the IMS retrofit failing after a certain amount of time or mileage? Or is it worth the extra $1000 to install the IMS solution?
