I wouldnt refer to your suggestions as corrections, dont you think thats a rather provocative way to have phrased that statement?
Anyways, my train of thought behind the bolt in, is that its… bolt-in. Meaning you can take it in and you can take it out. My car is my summer DD and trackcar so i dont think a cage is in my best interest. I’ve heard lots of people having trouble insuring caged cars. A roll bar by cusco can be had for anywhere between 300-600 whether its from a shop or used. i personally think thats a pretty good buy. For peace of mind, especially knowing i have a rough and unrefined driving style.
I’m not even going to address your comment about megans over stances.
