Yeah, I know I should fit solid rears but I like to go there as a 'street car' rather than a race prepared one if you know what I mean. I will have all 4 seats, a parcel shelf, jack, spare wheel etc. I know im pushing this a bit with the welded diff, but if I cant drive it there then it wont be going down the track with it. Im just not a fan of people who say 'my car runs these times' when infact that was with different tyres, suspension settings, no seats etc. Anyone can do all that stuff to make their car faster so I just dont see the point of doing it just so you have a number to brag with, it means sod all when you are sat at the traffic lights next to someone

Karlos, its good to hear from someone who tried welded diffs. I will be very careful when I try it on the road as you suggest its pretty awful, I will persist for now but if its as bad as you make out then I dont think it will be in there very long.
