Hello all:

I'm a new user and need some help. I have a 89 C4. I've been working on it for about two years now, the car sat for many years. So I immediatly pulled the motor and rebuilt it. I've replaced or rebult most everything now. It runs very well, but it has some suspension issues. I ran it in the silver state classic last September and lost the tranny. I've run this many times in a 73 Pantera but this was my first time in my C4. I have just finished the new tranny, but I know have a few more items to fix before heading back to the May race. Here's my issues and will try my best to explain.
While on a long stright the car will loft up and down on a road the isn't perfect. It does not do this undere normal highway speeds but above 100MPH it starts. Also when in a turn and hitting a little bump in the road the rear end will want to skip out. I'm going to be buying new shocks this week, but am not sure what to buy????

Also what is the best seat to replace the originals. I've got the ASM harness bar installed. The stock seats pushes my head forward when I have a helmut on.

Sorry for all the questions, but I'm learning.
Thanks Everyone
