i spoke with owner
PDK is new b/c the old one didn't have LSD. to install a good after mkt LSD, the tranny must have oem LSD to begin with. so, owner put a new cay r PDK in the car (they come with LSD from factory), then worked in the aftermkt LSD.

 

Correction, at the time this car was built you had to have a factory LSD gearbox if you wanted to replace it with one of ours. Subsequently we have produced one that will fit in the non-LSD PDK. However due to size constraints it is a much smaller unit. If I was building a racecar I would still want to start with the factory LSD version of this gearbox.

Ps. The open version is so popular that BGB has sold out the whole first production run in less than 6 months. We are making more.

Sorry for the hijack. Back to the sale of a nice car...

 

I have one of these LSD's and the change in performance is staggering. Also, my rear calipers are not chocolate, so I am assuming the LSD might factor into this. Downside is they run hot, so a cooler is in the works.

 

I know it is built to the GTB1P rules but can you confirm the weight of the car.
