I have noticed that the S5 came with VLSD. the information i gave was talking about the S4 NA clutch-pack LSD, which is the same construction as the T2 clutch type, but different final gearing(dont remember well, but nothing a single search on any FC forum cant fix). The article is huge and posts on the piston swaps are lengthy and abundant. I just found couple KA swapped into FC that I guess were completed within last year. tons of SRs, 1jz, 2jz, RBs. I gave a very small portion of the article that i got it from. I dont bloody care anymore to go on on this. grannyspeedshop.com and read up. dont forget to use the search on piston motor swaps into FCs. Just make sure to type in the motor codes rather than "piston swaps", nothing comes up under that. I would of thought a car that ran Mid-10s would of gave a way the fact that it needed to be launched rather than just drive it like around town style. If that car didnt launch off the line to get a mid-10s...I would love to see its 1/4 times when it does.
