Not quite sure what the mustang had to do with this but I got the idea lol. Does anyone sell aftermarket bump stops? Someone has to lol. I'm on a Koni Sports (yellows) and Neuspeed Sport Springs (green). 1.75" drop up front and 1.5" drop in the rear. Obviously I would have plenty of travel before the bump stop because 1.5" drop is usually what Koni recomends with sports but since I have them off and apart I figured I would make them like new. I just replaced the spring isolators with the Energy Suspension Poly ones since the stock old ones were all beat up. I think I'm just going to call Koni and see what they have to say.
