Hello and nice to meet ya! You can try to edit the chassis config file the file path is:
Street Legal Racing - Redline\cars\racers\car name here\scripts
Usually it will be named as "_main_car_name.cfg," Open it with notepad, you will see lines like this:
P.S. I took razine's Fit for a quick example as I can't find the Mazda 2.

You will find a regular pattern of slottype, e.g. 201, last digit is "1", which means it belongs to the left side of the car, first digit is "2", I... think it means "clickable"?
In this case, FL spring is supposed to have a slottype of 201, but the author typed 501 by accident, so all we need to do is change that digit. 501 -> 201, done! You can now adjust the front left spring!!
