My G37 is 11 years old. I'm sure the bushings are dry, cracked, and or rotted. Looking for replacements. Some googling found polyurethane subframe bushings. Are rubber ones available? Not interested in metal.

Control arms: Anyone know if the Infiniti part numbers for the suspension bushings are the same in the US and Europe? I'd prefer not to install polyurethane since I can't stand the squeaks. The reason I ask, many marque's have stiffer bushings in their models destined for Europe. Hoping to get lucky.

What other options are there?

 

I was wondering, is there any advantage to going aftermarket A-arms/control arms etc?

Most of the time, they are installed when a greater range of adjustment is needed for racing or extreme lowering to maintain the needed alignment specs. I've upgraded to polyurethane bushings on two previous cars, and loved the improvement that it made in steering response and cornering.

I'm in the process of gathering the parts to convert as many bushings on my G-coupe as possible now, but haven't started the installation.
