Is the Turner Rolex GT M3 running the DCT?

Or a sequential tranny? My assumption is a sequential - but I saw a video recently that made it seem like the DCT - it was seamless and immediate on both upshifts and downshifts.

I see 3 pedals in the first vid on the GT car, so it must be a squential box. I don't know how reliable DCT/DSG boxes are for endurance racing, and I assume they are heavier than a squential box.

Also remember that that the Rolex GT car is not really an M3 - just looks like one.

It is a S62 not an S65 and is a full tube chassis car like every other car in the class with the exception of the Porsches which are a factory tub car.

They can run a transaxle car at a higher weight.It is a great class to watch

It's a sequential box with automatic ignition cut, that is, zero lift upshift (perhaps downshift too with auto blip). The clutch pedal is only used when starting from a standstill.

I'm not sure its a full tube chassis...
I remember seeing the Rahal/Letterman GT2 up close and it looked like a tub chassi to me.
But I could be wrong.

Also, I've been in touch with Drenth and Xtrac (manuf of sequential magic)
Drenth has a sequential that mates directly to the S65 @ $18k USD
It weighs 100 lbs less then a DCT tranny
I believe that the R/L GT2 uses a custom Xtrac

The ALMS & Grand Am rulesets are 2 totaly different animals.ALMS pretends the cars are based on production cars but allows some pretty wild differences like an M3 runs with a transaxle and has a lot of underbody aero which is not allowed in Grand Am which results in a very expensive race car and small fields.Grand Am GT works on the Nascar formula of having lots of cheaper race cars and having larger fields.Look at the limited modifications allowed for the engines and quite a few of the cars have to run a stock sealed engine in order to meet the rules but it is still a very diverse interesting field to watch or compete in.
