I cannot speak for Street boogies product, since I made my own, but mine have not had any issues....now I used extra long rubbers on mine....and clamped the holy he!! out of them. Also looks like the ABS 180's I used are a tighter radius..and did NOT paint the insides....that can only lead to trouble. Anyway...I hope this helps.
