Ok so the only thing that goes between the two disk's would be the tape? I thought that people put lub in there. I was wondering about that...what would keep it from coming out. As far as the shock goes, I understand that...I did run my car last week on a very small track and It did start to feel like the car would unload when I drove it hard. I was told it was the diff being too tight but i think it could be the shock as well....god knows when it was built. I have to get a new axle so the diff will get rebuilt anyway. Is the L4 axle the one to get or is there another out there to get?
