My Aircon is leaky too, but it does last 18 months or so between recharges... And the condensers have definitely seen better days.

Is that uv sensitive stuff in all Aircon systems? Can I get a UV torch and try and find my leak?

Normally some common places to look to check the pipes if the condensers look ok. They run just beneath the sills on driver's side and stupidly close to the jacking points so can easily get crushed if they're not careful. It might be obvious if you have a look at the pipe condition. If not then it might need a full test. My condensers were shot but the pipes were also knackered.

Agree with this. Common places are condensers, or where the pipes join the condensers (rubber seal degrades) and the pipes under the car.

I've had a look at my pipes and they are in not great condition but look ok - no obvious wetness. The condensers are not in great condition though, definitely need replacement.

The zircon on mine worked perfectly during the test drive. Following the PPI where they replaced one of the condensers it no longer worked. I assume there's a good chance it just needs gassed. However, In 3 years I've only ever had 1 long motorway drive on a hot day where I wished I had air con.

Have been following this thread and others like it for a while and finally pulled the trigger on an upgrade from my 986 putting down a deposit on a 98 C2 last night.

Spec wise it's exactly what I wanted:

Zenith with full factory aero
GT3 look split wheels.
Manual
No Sunroof
Hardback sport seats

It's also had a pretty much every single mechanical component / suspension work possible done over the last few years including an engine rebuild. So I'm hoping it's going to give me a couple of years without too much pain. smile

Picking it up at some point next week and very excited. Have a trip to caffeine and machine planned at the weekend as a first run out.

Gratuitous pic below!

Alan - 87, aerokit 996s are relatively rare even amongst the PH group, but amongst my group of friends we've 3, but they’re all C4 manuals (the 3rd is another silver one that's missing from the pic as rarely gets driven by my friend rolleyes ). We’re about 1hr from C&M btw

Yours are looking well MrC.

A good mate of mine has an almost identical spec to the one I've just brought which he's evolved into a kind of Club Sport Spec over the last few years.

Would be interesting to know how many aero kitted cars were actually supplied.

Mine's been on a diet too with fixed back Cobra Nogaro bucket seats installed, rear seat delete, plus a CAE shifter amongst the various bits & pieces done (interior bits retrimmed as well) & a lighter exhaust system as the OEM boxes are overly heavy. I've done the normal suspension refresh plus full engine rebuild etc. Mine's a keeper now hehe

My one friend (with the silver C4 in the pic) has a car that had a dealer fitted full aerokit in the past so it's not unusual to find this happen, albeit an expensive way to get the aerokit.

My mate with the 996.2 has a little oil leak from the rear of the engine which has been getting progressively worse. He also says he sees some coolant mixed in the catch tank under the car. Water pump was new 2 or 3 years ago. Does anyone have any ideas?
Thanks

How many people are tracking their 996s? Any issues if being run on standard rubber?

My car was tracked by a PO. That's why the rock hard suspension and bushes and what not. It has x51 baffled sump but he ran semi slicks so not standard rubber. I think the general advice is the m96 engine doesn't like higher lateral g. I suppose it depends how hard you want to play. The PO mentioned cracked a head and then sold it to my PO who rebuilt the engine at home in his shed. I'm not sure if the track use cracked the head or something else caused that failure so take from that what you will.

I'm still tempted to try some track action but so far not found the time or enthusiasm. I would probably caution that most modern rubber will be a lot more grippy than 1998 designed tyres and therefore even standard rubber bought today will have a lot more grip than anything around back then. But its just a car so you can do what you want with it. I believe the standard brakes can get a bit hot too. My car had some very dusty and grumpy pads. I believe for little stints you just need or want some pads that can deal with higher temps.

My thoughts along these lines too.

The higher lateral Gs and the associated potential oil pick up concerns lead to the baffled sumps etc. But I wonder how high the lateral G would actually be given road tyres on a regular trackday.

I did a few laps of Castle Combe at the April Action day yesterday. Didn’t push it to hard so was just a bit of fun but everything behaved impeccably.

Yep no problems on Goodyear eagle f1 assy 5. Even with standard geo, running m030 with h&r rear anti roll bar I was wilting before the tyres. Yellowstuff pads with otherwise standard but good condition brakes worked very well indeed too.
