hello everyone, has anybody had any issues with ap coilovers. ive barely done 3000 on them and the dust cover on the bump stop on drivers side front has cracked all the way through, and the passenger side will not stay done up for long which means i have to check after every hoon or the nut undoes itself. also the rubber that seats the top of the rear springs to the car has collapsed into the spring do i get another standard one or is there a wider rubber i need there wasnt anything with the AP kit. cant post a pic as im a newbie still if any1 can help ill email some pics of what i mean and i think i have found the part number 1J0512149B underlay upper. i think thats what it is. thanks in advance
