Can you draw up what you're thinking?

Remember, you MUST have at least 5" of head room (you'd be surprised how much you body will flex in a crash)

Most of the cage designs are strong and safe as is. The primary concern with changing anything must always be safety. No one plans on being in an accident, but if you plan for it, most of the time you can walk away.

K-Fab is right about the 5" rule. There are safety specific rules like this that apply to all classes in all situations. Don't just make it shorter for "the look" which will do VERY little in the way of performance or handling, when it may impact your ability to live or walk one day.

That being said, if you want to play around with a design, thats how better buggies get made. Looking at the ST3, there is not a lot you could do to flatten it out. You might be able to lay the seat on more of an angle, which would require less height to fit in, and you would probably need to stretch the length as well.

As a first time builder, I really recommend using plans. You can chop and change things as you like but it gives you a reliable starting point and something to fall back on. I think most scratch builders here would agree that plans are a good starting point, as most of the kinks have been worked out already.

i like the look of them but the roll cage i hate

What part of the look of them do you like? Is the shape of the cage not the majority of "The Look"?

If by the look, you meant more generally the features and specs then ignore my comment. It just came across as "I like the way it looks, but I hate the way it looks."

BTW Kfab and Hambam would not lead you astray. Listen to their advice. Beyond safety and performance concerns, build whatever you looks cool to you.
