Hello fellow Lexus enthusiasts... I am looking for a shop or someone around the Bay Area that does any type of fiber glass extensions or if someone has a vertex rear lip. You see about 3 months ago I have bought a kit, the kit sits flush in the front and side.,BUUUT the rear lip is about 2-3 inches away on each side to the point where I can't put my tabs so it can hold onto my bumper, if anyone can help with that or point me to the direction. I tried to speak to sonic motors but they never followed through since I bought it from them. Thank you in advance
