fronts are ok but the rears seem to have too much offset. The stock 18x10 rims have 65mm offset and probably the tyres will rub the fenders.

Try them if you can before buying.

it is a RoW 2001, 996 C4 convertible

I've been doing some research and apparently the Alfa Romeo ICS systems, which are very similar to the Siemens PCM1, have those functions enabled and people have connected DVDs and all kinds of stuff

Hi,

according the the car wiring schematics, the PCB1 has an unused RGB input with all the connections available (RGB plus SYNC) and what it seems an enable pin (RGB ON in the schematics).

has anyone tried to connect anything to these pins and be able to display anything on the screen? I'd be interested on the functinality of the RGB_ON pin as well (ground to activate?). 

If it is implemented inside the PCM1 I am thinking of using this unused input for a backup camera for example. 

cheers!

I live in Hong Kong so prices may be different to what you can get but a new set of LMs here are around 3,500USD.

Maybe in Europe you can find them used? 

I'd suggest BBS LMs.  I was like you few months ago and finally went for those. 

It is bolted on both sides but probably full of freon so I don't wan't to mess up with it much.

I guess if I take it out I'll make a mess / will need to recharge the aircon. 

I am not sure if dealing with the aircon is as "easy" as just let the gas escape and then get it recharged or some other precautions need to be taken

Mine is a 2001 pre-restyling, maybe they rerouted that pipe...

Hi,

few days ago I decided to fix the foam flaking over the car ventilation and the lack of hot air by accessing the air mixing flap through the heater core.

To my surprise it seems not possible to remove the heater core easily in the C4 because an aircon pipe crosses over it (see attachment). I'd would guess that I'd need to remove the offending pipe and the recharge the aircon but it would be great if anyone with the same experience has some input about it.

thanks!

Thanks Loren and Dharn, it is clear to go for ET65.

thanks a lot!

seems that 10" ET65 will be the way to go :-)

295 should need a 11" rim, right?

mine is the pre-restyling body. maximum tyre in the handbook is 265, would it rub the fender or other internal parts. The restyled ones with the new headlamps have the 295 tyres and I think I read somewhere that they come with widened wheel arches

Hi,

has anybody tried rear 10x18" wheels with ET50 in a narrow body C4?

I got a 2001 996 C4 cabrio and I am considering changing the "boring" stock 17" with BBS LMs. The rears come in two different offsets, 10x18ET50 and 10x18ET65. ET50s would look more aggressive but not sure if they fit at all. As far as I know recommended is ET65 for a 10x18 wheel.

Tyre will be a 265/35/18

thanks a lot

I'll try the color match route. Thanks for the advise.

Hi,

I have some scuffs in the interior plastic parts and was wondering if anyone knows of some paint I could be using to touch them up. It is a 996 C4 convertible in savannah leather in Hong Kong. Porsche doesn't seem to sell any but perhaps some enamel paint for models or anything else could do. Obviously colour match should be perfect, otherwise it'll look even worse than the original scratches...

I've seen this post from many years ago but seems no solution either  http://www.renntech.org/forums/topic/474-savannah-beige-touch-up-paint/

thanks!

I'll check, thank you !

sure, definitely that's also an option but the amp has 4 inputs for the front/rear and left/right balance capabilities. Ideally we would need to patch the audio before the balancing and equalization is done inside the PCM.

If I finally decide to hack the cassette side I'll create a tutorial for it.

Hi, no answer yet... If I am in the mood I may disassemble the cassette player and try to find where I can inject the external audio (I am electronic engineer) keeping everything else working.

As for the CD player you can insert audio through the plug C3 behind the PCM1. It is the blue one on the top right when looking the PCM from the back. Connections are:

pin 19: Audio Left

pin 20: Audio Right

pin 18: Ground

You'll need to keep a CD in the player.

Hi,

I got a 2001 Carrera4 which is equipped with the PCM1.0 and its cassette player. It would be great if someone has the cassette player electronics schematics which can share with me. I am planning to modify it to play any external line source.

I am aware of using the CD player for the same purposes but I want to keep it working.

thanks everyone and happy 2013.
