Do they get any squeaks and rattles? Yes the 08 rattle like crazy but it can be addressed. Also please note the GSR has less sound deadening material then the MR's do.

Have any been getting any rust yet? Nope..

Any other quirks about them I should know about? Yep, buy a 2011 if you can, that was the year they addressed the diff pin issue, fuel relay issue, and the tunes were better from the factory.

Probably get one that is already modded and looking to end up around 375-400awhp at DB. "Good luck with that, it probably will not happen on stock turbo or sst with out some serious coin"

Do all of the twin clutches on a X rattle or are some of them ok? They all rattle.

Are there any modded SST cars around, ralliart or MR so I could check one out? Not that I am aware of, but I would go MR if I was doing it again.

I would love an MR, but am a bit scared of the tranny. The transmissions are good as long as you do not go crazy with mad power goals they has been some breakthroughs in programming that make them more reliable
