Make the frontal and rear distance values easier to type in and use.
In the common parameters max frontal / rear distance. It's hard and finicky to use, if you click and type it always messes up, loses the decimal, overall sloppy and frustrating. Make these bigger, easier to type in and use to input values. Not a fun part of the process.
Example I just tried to click on the .01 to change it, and the slider bar is 'so close' to that field that it yanked the slider bar value to .987, making me try to click again, ,then type again, ,and when you type it mucks up and highlights / then doesn't / then removes the decimal.... you get the idea.
Also to post this suggestion being forced to log in while busy at work is silly - (5 minute fuss to find the password for this again) make feedback EASY it improves problems with your product.
