Will you be doing DEs or AXs or just street driving?

The IMS in the M97 engine (06-08 Cayman 987.1 engine) has a 1% chance of failure. The 987.1 has other issues that need addressing if you plan to track it. No need to address them if you just plan to do street use.

I do approx. 4 DEs / yr with my 08 CSS. I changed the oil baffle, make sure the power steering is at the proper level before each DE, and shift at 6K rpm to alleviate pressure on the rod bolts. No problems in 4 yrs. My 08 LE is a fair weather car. I don't worry about IMS issues in either one.

For the price difference between the 987.1S and the 987.2s you're looking at, buy the 987.1S and save the $10K IN CASE you blow your engine.
