Originally I had no soundproofing in my GT. It was an echo chamber and I think it was actually louder in the car than behind it. I haven't read through your build thread but if you haven't put some effort into noise attenuation, it'd be well worth it. I did a modest amount and the difference it made was enormous. Without going overboard, people who have been in it are surprised to be able to converse underway.Having a loud cool exhaust sounded good in theory. However, it’s just too damn loud with the cutout still closed. The big venture is going to be redoing the exhaust, with the cats installed as well. I cant step out of the car without smelling like exhaust fumes.
You may want to try drilling out the holes to the appropriate size and epoxying in some helicoil inserts. This is what I did with the windows and headlamp covers for my GT (at the suggestion of someone else) and it has worked well. I forget exactly what I did to size them correctly but a little trial and error should set you set up and then do it for real on the car.I’m also having issues with bolts rattling out of my ceiling and side pods. I highly suggest going with at least an 8-32 to secure the panels with some blue locktite.
Yes sir that was the plan to make them rectangular with measurements that suffice for both front and rear. Hopefully out of pink foam first. Make one mold, fiberglass them then fiberglass them into the body.The RCR supplied set is not symmetrical. One will fit on the l side and the other on the r. If I were to make a set, I would make one mold and then use the one re-designed style on both sides so therefore much less mold construction.
