I was curious how people think modifications to our cars affect resale value? I have a nice 997.2 GT3 and have a set of coilovers, and a rear diff installed. I was thinking about installing the cup bumpers front and rear and didn't know if that was going to hurt the value of the car in the long run.

Thanks!

 

If you do high end parts and oem parts you should be okay. I'd keep all of the stock parts and put back to stock when it comes time to sell.
