Not quite correct. The "07" V-Specs have an extended ridge on the bottom of the crankcase that runs all the way to where the front crankshaft bearing sits. That ridge only runs halfway between the front and rear bearings on the "06".

Both versions have the same bubble wrap packaging inside the box.

Also, the 06 V-Specs have an 8 ball rear crankshaft bearing, where the 07's have a 9 ball rear bearing.

Here's a picture of an 07 V-Spec. Notice the ridges on the bottom which go all the way along the bottom of the crankcase.

BTW its the C6BB7T not C6BBT. Well, I believe the C6BB (non-turbo) is no longer produced, but still sold if the resellers have not sold out. I have not seen a place to buy a non 7T for quite a while. But yes, proper break-in is essential on any race motor. On my standard C6BB I already put the 7mm venturi in for most race occasions (which the 7T comes with stock) but I do not believe I need any more power at this moment. (I really don't think anyone but the pro-level racers need this power, but its always fun)

Thanks for all the advice, I really appreciate it. I got the v- spec only problem is it is a 06 version I didn't understand the ridge until I compared the two. Is there anything I should do like change the bearing before it goes or just keep a close eye on it.
