You are talking "performance" mods, I think. If you can do the work yourself, you are in great shape, I think. If you have to pay for it, and pay for any problems created, it becomes much more iffy. I don't think mods are going to affect the value of too many cars, maybe some 2010's, Z/28's, maybe early 1LE's or ZL1's. That said, don't expect to get money for your mods at sale. Past that, I think it comes down to what you want out of your car. If you are never going to race it anywhere, does it make any sense? Depends what you think. Do these mods count at car shows? I don't know one way or another. I'll guess maybe so. If you are going to the track, I'm going to opin that you will need the mods. If it is just for a look or feel that you want, no harm done.
Offhand, I've only done things that are mostly for looks and maybe mildly for function. I'm still debating where to go. Right now, the only thing that I can't reverse, is the holes that were added when I put the splitter on. I'm not going to do anything that causes problems with my annual inspection and I'm probably not going to do anything now that would affect my warranty. Different strokes for different folks, its all good anyway around.
