Hi everyone,

Having been a long time Rennlist member back in the Lyris times, I have now re-activated my account.

I own a black 911 3.2 built in 1989 that has been (partly) converted to Ruf spec. Still being an aspirated engine, it is now a 3.4 litre with a few modifications pulling about 280 bph and 236 lb/ft.

Since it is time for a clutch replace and a conversion to a 993 RS clutch system won't work because of the 60-2 timing, I am thinking about a lightweight flywheel and a lightweight pressure plate.

Has anyone got exerience with this conversion and can recommend a manufacturer? What about Patrick Motorsports?

Kind regards,
Frank

Hi Frank,

I have an 89 Coupe as well and i'm currently using the Patrick Motorsports lightweight flywheel and pressure plate with great results.
Although my car has a 95 3.6 in it now , if I remember well , the parts were on my 3.2 and were compatible with the 3.6 as i ditched the 993 dual mass flywheel when i installed the engine.
That was a few years ago but i'm sure somebody will chime in and add their comments !

I had a Patrick Motorsports LW setup in my Targa when I used it for DE events. The only drawback was that clutch pedal pressure was much higher than stock, a bit of a workout on the left leg ! That may be different nowadays though....I'd call Patrick MS and discuss it with them, great products.

I have an '88 3.2 with 964 cams and I did a KEP light weight pressure plate & clutch.
Saved about 10 pounds in rotating weight, and have a much firmer clutch pedal, I'd say +50%.
It's quite still drivable, but definitely takes a bit more finesse getting off the line than my buddy's '87 with the stock clutch.

I could be wrong but don't think you're going to have an easy time finding any aftermarket flywheel
that works with the Motronic-bad tooth count. But the pressure plate is the heavy bit.
Why not just go with a KEP plate?

Very helpful, thanks very much everyone.

I have an aluminum flywheel in my track car. The biggest improvement I've ever made.

I have the KEP Lite pressure plate with a 930 spring centered disc on my 3.4L. Still using the original flywheel which is already fairly light. I like the setup, but I do get gear chatter engaging first. Just have had to slip the clutch a little more.

You may experience an issue with the idle. Perhaps others have not had an issue this problem. This can be addressed with a remapping of the chip. Others may have more input about the idle.

I have a PMS lightweight flywheel and its a quality part and well balanced.....don't hesitate to purchase. FYI...My 73 runs a 3.8L hotrod engine and the chip remapping didn't get rid of all the lumpy idle but I could care less myself, a lumpy idle is simply a warning of whats to come with some revs lol

There are a couple of aluminum pressure plates on the market for the SC/Carrera, Patrick of course, and the other one escapes me right now although I installed one hot 3.0 just about a year ago.

Also, I prefer to use the Sachs aluminum sport pressure plate as provides a nice balance, and no additional pedal effort. I have this on my twin-plug 3.4 as well. As noted by some, you may have to get used to your clutch/gas relay when moving from stop until you get used to it.

The only lightened pressure plate option for a G50 is KEP.

Believe you're correct.. didn't see he was G-50/
