Let me catch you up to speed then

Stock old shock up front and MP long rear shock(also vary old)
I think that brings us up to speed...... o yeah its a 70 plymouth Barracuda.

After watching my video. I realized that some may have not seen the hole video because, the last launch from under the car is in "slow mo" and it take a minute before i launch the car. There is three more from up front of the car.
