C6 Vette and Z51 pack?.
Discussion
The Z51 pack is a standard fit on UK supplied type approved cars and can easily be identified by the presence of cross drilled ventilated discs.
Let us have VIN numbers of any cars you are looking at and we'll give you the spec and history.
We also source Corvettes when we don't have what you're looking for.
Manuals are comparitively rare but infinitely superior to the four speed autos at least in performance terms. In city traffic, you'd probably take an opposing view.

As David said, all UK cars are Z51 specification, as the standard suspension was deemed too soft for European tastes. There is also the extremely rare Euro spec 05 model year magnetic ride cars, which confusingly also came with the Z51 brakes and oil cooler (manual transmission), unlike the US spec.
Read the US forums and arguably the larger cross drilled brakes have little benefit on the track, but under foot they do feel more reassuring.
Having spent a bit of time in a US spec standard car, the Z51 is considerably better tied in to the road, and the shorter final drive ratio makes quite a difference also (even though the gearing is still stellar compared with rivals).
Originally the car would have had F1 supercar tyres, rather than normal F1s. Most of the original batch of C6 in to the UK were autos (an accountants decision at PDG head office...), so earlier Euro spec manuals are quite rare.

Remember there are two radically different auto versions, and it's no accident that so many Vettes are sold as auto
1. The 4-speed, pretty much the same as previously fitted to C5. It works; period.
2. The 6-speed paddle-shift. Completely different, much more up to date and IMO very good. Fast smooth shifts and quieter motorway cruising with better mpg.
Suggest you try a 6-speed paddle-shift before you rule them out completely!

Sorry to pick you up here, but the 'box in the 2005 C6, although a 4-speed auto like the C5, is a very different 'box altogether. My only complaint with my auto C5 was the 'box and this always put me off getting a 4-speed auto C6.....until I drove one. The two are totally different.The C6 4-speed auto is very sharp and the changes are sooo much faster than in the C5 auto 'box. There's no slop in the 'box like the C5 and it responds instantly to throttle input. I'd say it was perhaps one of the most noticeable changes to be made for the C6. (along with the improved handling and subsequent grin factor - although C5 handling was impressive as it was)
Any other differences over the C5 can you give.B.t.w. I did a show during the summer and was talking to the owner(F15 pilot) of this Z06..............
He was having a good look around my C5 and commented on how he missed his old C5,as it was the "complete"car

Whichever way you look at it the 4L60-E in the C5 and strengthened 4L65-E in the early C6's are closely related in comparison with the radically different 6L80 paddle-shifter. Some details here http://www.cadillacfaq.com/stsfaq/tsb/data/tsb/05-...Yes, GM is a world leader in automatic transmissions.

Perhaps I should have been clearer, but I was looking at this from the drivers perspective - not from the technical viewpoint. I felt that when you originally said that the 4-speed was "pretty much the same as previously fitted to C5", this gave the impression to someone who hasn't driven both, that the two gearboxes would behave/feel "pretty much the same" from the drivers point of view.
I just wanted to point out that when I had the C5 with the 4L60-E, the gearbox was the one thing I really didn't like about the car. I was more than aware of the technical similarities of the two 'boxes and this was actually putting me off getting a 2005 C6 with the 4L65-E as I thought it would be too similar to the one in my C5.
How wrong was I? The 4L65-E feels stonger and sharper. The transitions between gears are faster & smoother and the way it behaves makes it virtually unrecogniseable from the previous 'box when you drive it. I make no comparison between either 4-speed and the 6-speed auto, 6L80 as I have never driven one. (Of course it's different from the 4-speeds!)
Looking at it purely from the drivers seat, the two variants of the 4-speed could barely be more different to each other. I thought that people who might write off the C6 4-speed (like I did) ought to know that although very similar 'under the skin', the two are indeed very different.

I think Z51 is great early Euro cars that had the Magnetic ride did not have cross drilled discs but this set up was more expensive! Never seen the point of the ride options I hade the F45 on a C5 never could tell the difference.
The Z51 on theC6 is excellent for the Uk I have a 05MY withe the 4 speed auto which is great, Also the z51 has different tyres to the US spec cars without that come over.
