New Owner:-2007 997 GT3 RS, a few questions


Recommended Posts

Hello All,

I`ve had my 2007 997 GT3 RS for just over 2 weeks, already loving the car..Its the best car I have ever drove on the road, still amazed at the noise and the way it just grips the road!

In no apparent order what so ever I have a few questions, niggles and also need advice..the car is 100% factory standard.

1) There is a "niggling rattle" from the centre dash area, reckon it may be some where just under the sport chrono area, its only at low revs, its now getting very annoying, is this a common fault ???????

2) The car is running on standard GT3 19" wheels with Pirrelli P ZERO CORSA`s (NOT CUPS), would changing to MPS2`s now give the car any superior ride/handling quality, the car is used for ROAD USE only.

3) Whats the best tyre pressure to run on the 997 GT3 RS for ROAD USE ONLY ?? Also I have the TPM tire pressure monitory system, how long does it usually take after re-setting, its still showing dash fault as its "learning" mode still...

Thanks to everyone in advance

Congratulations to your new GT3 RS, like you, I love mine!

I use the recommended tire pressure 29 and 33 for road use.

The tire pressure monitoring system is not accurate in my car it usually indicates 2 lbs less than the pressure I confirmed with my Longacre $200 pressure gauge. Drive the car for 10 miles and the pressure indications should slowly come back and indicate. I had the same problem on mine, it is just very slow calibrating itself.

I have MPSC on mine but was told the Corsas are equally as good in the dry and in the rain they are better they are also more expensive.

My center console rattles as well I think it is a rattle coming from the side pannel on the center console surrounding the radio, I increase the radio volume and the rattle is gone.

Enjoy your new car!

For tires, you can look at the hardness ratio. Go to the site



The softer the tire, the better handling but also shorter life.

The Michlen Pilot Sport Cup Tires are real soft, but

you may only get two days at the track before you need

to replace them.
