@Ericv8thunderbird at 1 point before my bird I was interested in a c4 like this, it seems like for today’s day it’s still a total weapon out in the road, it’s pretty light, handles great and looks awesome. In my research I found these 3 braces that (based on reviews) would fix a lot of the rattles it has, I read it was originally a solid roof but at the very end they decided to chop it to a targa.
I will attest to the targa brace, my old del sol had a X brace from a fellow member back in the day and that thing made a world of a difference. Very noticeable over beat up roads and driveways.
