Can you use stock replacement rubber bushings in place of the poly ones in aftermarket LCAs? If not, does anyone know of somewhere you can buy rubber bushings that fit in them? I have a 4th gen that will be a daily driver and do not want the noise or harshness of a polyurethane bushing, but would like the adjustability of aftermarket suspension pieces.

 

Try BMR, they sell LCAs with ruber bushings. I've had mine for years, they work well.
