I have an LS1 Engine in my 55 and it has 530hp. I am in the middle of cutting out the rear end and installing a 9" Moser rear-end, tubing it to install 12" wheels. My question is this, at this point I am being recommended to install a roll bar. I particularly do not care to install one, (don't like the looks of it on the inside) but being that this car was never designed to have this type of horse power, should I install a roll bar? The car is a street machine and I doubt that it will ever be raced. What are your thoughts?:
