It s time for new discs because the break pedal and steering wheel vibrate when I apply the breaks. I brought them to tham machined and the mechanic told me they were do depleted and it was nt possible. I dont need performance discs cause I only daily drive and of course the occasional vtec and break. All the parts stores have two kinds of discs the good ones and the cheap ones (economical). But the price difference is big like 50% more expensive than the cheap ones. Should I try the cheap discs or the more expensive. The clerk tells me that economical ones will do the job just as well as the expensive ones and not to waste extra precious money for nothing. What do you guys think I should go with? And then there is also the stock discs from acura which are way overpriced but probably the best quality.
