No doubt Puddy is a great installer but having to pay for shipping is an extra cost. Rear end specialties has done more than a few S2000 and this is all they do is diffs. They have been around for quite a while. If I had to do it again I would use them again I have no complaints. If you want your diff reinforced then the puddy diff is the only way to go.

Here' s a cheap way to give your dif a little more strength while they're in there. Check the bolt lengths on the cap that holds the pinion gear. I think you'll find you can replace them with longer ones and harder too if you like.
