I am installing a new IRS suspension in my 73 corvette that has both upper and lower control arms with a CV slip axle. I am fabricating my own upright and my question is if king pin angle is important with an IRS set up. Can I set it up vertical or do you need it at an angle like the front suspension. Every article I have read is for a front suspension and I just want some clarification before commenting to a specific design, thanks.:sos:
