DirtRacer, Hi. The best advice I can give you is to pick up a chassis book.......You will be surprised how much there is to learn......The questions you ask are difficult to explain in just a short post here........to explain them well enough to actually do you any good......

Buy the book....gain a basic understanding ....... the book probably won't tell you what springs,shocks,etc to use........Thats where the forum will really help you......these guys will share with you what works for them and help with any problems...........

The center of gravity of your car........that is the center of your weight.........if we could hook up a crane to this point........the car could be lifted up in the air without skewing up or down or sideways.........in short, it is the balance point of the cars weight..........

The height of this point is the "center of gravity height"

In general,race cars will want the cgh to be as low as possible,however, dirt cars will use a higher cgh than asphalt cars........

The higher the cgh, the more roll the car will have........but it's much more important than that..............

In general, mount everything as low,left,and rearward as possible..........

Roll stiffness.......is just that.......how much roll resistance you have......front and rear........stiffer springs and anti-roll bars add to the roll resistance...........

Travel...... how far something moves....usually guys will measure shock travel.......to tell them how much the suspension moves........just a tunning tool to help them find where improvement can be made...........

Buy the book........and read through the forum......you will find the answers to many questions just reading through the older posts........AND ask questions here.......someone WILL help you.........

Welcome to the forum

Good Luck,
Snowman
