With that early a number you very probably had the suspension replaced. It may not show up as a recall because it was held at the factory and not delivered to a dealer until the suspension arms were replaced, therefore it was never officially "recalled". My number 298 has the machined replacement arms but it doesn't show as being recalled either. But it falls right in the date range for the cars held for replacement parts.
Don't let that bother you though. The machined pieces are much prettier than the later forged arms and are just as strong. Jamal Hameedi, the GT Project Manager, told me that they used exhaustive testing and stress tests looking for the right aluminum alloy to use for the recall arms. They are not just off the shelf billet aluminum. We will never have a problem with them.
I think too much has been made about this "early vs late" comparison. They all have their little idiosyncrasies and when they were built has very little to do with it. Drive the hell out of it and enjoy it!! :cheers
