DCT and DSG are vastly different, not really the same mechanically speaking

Really? I thought that a "DCT" is just the generic term for a dual-clutch automated manual transmission, where "DSG" was VAG's trademark name for the same technology. Like Porsche & "PDK". Obviously not having interchangeable parts, but the same idea of a dual-driveshaft, dual-clutch automated manual.

Genuinely curious here - can you describe how is a "DCT" vastly different from a "DSG"?

They're the same thing, just different names. just like manumatic/tiptronic/geartronic/sportronic/touchshift/etc refer to the same thing.

Oops my bad. You are right. I got it mixed up with the SMG sorry.

There are wet and dry sump dual clutches. Each has its own capablities, strengths and weaknesses. Its not all the same.... geez...

you mean wet and dry clutches, not sumps, right? They are the same mechanically. The difference is that higher power applications use oil cooling to protect the clutch from overheating and slipping during hard acceleration.

Yeah, they are rated for different types of performance. That's what I'm saying. A DCT is a DCT, But the DCT in the. Focus is not the same as the DCT in the GTR or R8. Get real with that part.

I get it now then. Makes me feel much better about my 7at. I have really grown to love it. Don't get me wrong, I love sticks as well but I'm not unhappy that I ended up with the auto. I just always wondered if I was missing out not having a dual clutch like my friend with the M3.

Honestly, the only way you'd be wishing you had a DCT is if you were trying to get 600hp from your auto and didn't want to spend $4k in prep to make the auto turbo friendly. DCT's can take more under that kind of load.

True and I'm not wanting to do that. My exhaust and intake will be the only performance mods I do. I'm plenty happy with the power it puts out. I've had it for just over a year now and love it more now than ever.

You should finalize with some JDM pieces like the rear light, the motor for the mirrors, jdm cargo net and clear tail lights.

A GTR start button livens up the dash too.

Cost

the Z is already IMO over priced for what it offers and DCT would drive that cost up even more

I also think with the Z heritage, manual is important. As more cars switch to DCT, the manual will become rarer in sports cars and there will be demand for it when most sports cars eventually become DCT.
