I have a high performance fwd car with 5 years of burnt rubber on the side skirts. I’ve tried bug and tar remover, wd-40, and degreaser with a DA and finishing pad and little came off. The dark spot is where I just spent an hour experimenting. plastic razor blade gets the chunks off but scratches the crap out of it. Something has to work

I told the shop I wanted toe out .1 degree in the front and toe in .1 for the rear. I asked why I got .3 degrees in the rear and his explanation went over my head. Do you guys think this is a good street setup for mostly straight line speed?
