Racers look here to help a newbie -Thanks

The answer you're looking for isn't quite that simple.
There are simply too many variables you're leaving out. Sure you're looking at a 10-sec. car but is it going to be dual purpose? Are you running a specific class? How much horsepower? What type of trans? Do you plan on travelling or just staying at one or two local tracks? What is your track experience?
From what little you describe, I'd go with the Cal-Tracs simply due to cost, simplicity and proven record. Both ladder bars & 4-links have adjustibility but you may not have the experience to deal with variables they offer. Go to the track & find a racer that has a car similiar to what you have planned & ask questions. I'm sure you'll find dozens of cars you can use as a guide but ultimately it's up to you what you want to run & how involved you want to get.
