One spot is on Pacific between Classon and Franklin. I have not been there in a LONG time but this Jamaican cat named hugh used to fix my 18s for my honda like 2-3 times a month!! (215-35-18 + 2.25" drop+ Brooknam streets= no good)
The spot is right next to a body shop, its real rinky dinky looking but they get the job done for pretty cheap (120-150 for a bend 75 for a crack).
Another spot is on Atlantic and Rockaway, but the dred kid there sends his wheels to LI to get fixed, good luck
