Terrible service. Sway bar bold bush was old dry and falling apart. These guys replaced the whole set with new bolts. Few month later sway bar bolt just broke across in half. I returned to them and they asked for money again denying warranty. They changed bolts again and in couple of months bolt broke again. I visited other service (won't tell the name so you would not think it's an advertisement). Other service said that those guys from Pitstop heavily overtightened both bolts not leaving any chance for required movements. So I got bolts replaced third time and guess what... almost two years later all good.
I'm shocked that this place is still in business. They don't seem to know what they are doing. They don't conform to their own warranty obligations making excuses like "we will need to contact our supplier to see if they are happy to replace parts". Seriously? I paid my money to you, not your supplier.
