Right guys! finally got these puppies! and got some more questions!
(Pics are in post 996 Turbo / GT2 Section)

Now I popped down to my local Porker centre to check out the seat set up on the GT3 and I was very surprised by the amount of space to enter the back seats when it was pushed fully forward (comparison for Turbo), I don't want to give up the back space, no matter what anyone says to me! lol, there was actually more space than the standard powered seats but obviously more space is achieved when the standard seat is tilted forward, anyway I really want to get my hands on a standard GT3 Rail/Slide Kit or something very similar, the kit over here (UK Cost) is bloody ridiculous, can anyone point me in the right direction for an urgent purchase?
