Northway just south of Reading (M4 J12) are also pretty good. Might be stretching the +1 hr a bit, but you are driving a Porsche...

Hi Peter
Just had my IMS done being an engineer I studied the different options. Didn't like the ball bearing LN version as they specify you need to check it every 4 years and for me that's about 8000 miles. I was looking for a fit and forget solution. Didn't like the idea of a permanent oil feed solution as the pipe is on the bottom and could theoretically be ripped off or they require connecting into other parts of the oil feed system. In the end I went for the EPS solution which is a theoretical permanent fix without the pressurised oil feed. The bearing is submerged in oil any way. This is a roller than ball solution and has no axial loading on the bearing. This is the version fitted by RPM Technique I believe. I also had a new RMS (Not actually leaking and clutch as it was nearly down on the rivets). The IMS bearing removed was in perfect condition, Both seals in place and runs as smooth as a babies bum. No play in it what so ever. Car is a single row 2002 C2 with 47,000 miles and full history. I also had a lower temperature thermostat fitted to reduce the risk of bore scoring.
So why did I have it done? Every time I took it out I was always relieved to get it home without it going bang, I knew it was unlikely but it was always in the back of my mind. ( Didn't think it would bother me when I bought it)
I took it out for a 100 mile spin last weekend and the car seemed so much more enjoyable. Silly I know but the brain plays funny tricks. Yes I could be unlucky and the new bearing could fail but at least I have done due diligence.
Unfortunately I don't live by the M25 as I am in Gloucestershire. Work Carried out by Peter Chambers at Tewksbury. Porsche Ferrari, Lamborghini and race prep specialist.
I expect your interested in cost under £1,700 including the clutch and VAT and the drilling out of a broken bolt. Genuine parts used except the IMS of course.
Hope this helps

Great post - very thorough, thanks. I'll be getting my RMS and clutch done later in the year, probs back end of the Summer so will most likely get the IMS done at the same time. I'll speak to Northway but I imagine they'll be aware of the different IMS replacement options, but it looks like the EPS one you mention is the best.
Hi Peter
I also went for the EPS bearing, last summer the engine and gearbox were out as i was having the brake lines replaced so I decided to get the clutch, usual seals, air/oil separator, oil pressure sender and IMS all done at the same time. I went for the EPS bearing for the same reasons as Cayman295, Autofarm carried out the work and photographed the process they were excellent always keeping me posted........................by the way the old IMS was in perfect order (33,000 miles)
