AUM/Markus,

Funny I was thinking of the same word to use in my reply. While it's hard to judge from web forum statistics, yes, US GT3 has RMS problem seemingly of epidemic proportion.

And for more gory details just search for rms in title here on rennlist's GT3 forum: http://forums.rennlist.com/rennforums/forumdisplay.php?f=141

Before I installed the Bilstein PSS10 in my Turbo, I had seriously thought of trading it in for a GT3. Besides the reduction in torque, I was scared to make the change due to the sheer number of RMS reported in 997 GT3's with GT1 engine. The strange thing is that it *seems* to be worse than 996 GT3, in fact *seemingly* worse than ANY 911 ever built, GT1 or not.

The most "exquisite" thing about this situation is that as of September 2008, PAG actually DOES NOT have a fix!! There are 997 GT3's that are on the third (or fourth?) RMS change. The 997 GT3 and GT3 RS are cars to be unloaded IMMEDIATELY when the warranty ends, IMHO. It puzzles me greatly that people are buying (and collecting!!!) that car still, while next gen. 997 GT3 is just around the corner, most surely faster because of pressure from for example that great but heavy and fugly Nissan GT-R (kidding... kidding... about the fugly, but it IS ugly, AND heavy).

The GT1 engine has been great in its Turbo version and as a race engine, but to me the NA version in the GT3 class has been a disappointment because of RMS problem (search for RMS in [url=http://w



The current GT3 actually also uses the GT1 based engine block I have not heard of RMS problems with the GT3.



USA GT3s have an epidemic of RMS to the extent that it is expected by many owners and used as an opportunity to change to the GT3RS lightweight flywheel (with reduced labor costs). Plus the USA cars get a compulsory sunroof.
