So I bought a crappy drift Z and am going through replacing a ton of stuff, all front lower suspension bushings, rear diff bushings, new coilovers.

One thing I'm concerned about is replacing the diff bushings I would like to also replace the trans and motor mounts but have rear a lot about an obvious immediate increase in NVH, I can take a little, especially in the steering wheel but don't want constant engine and gear noise, this car isn't exactly an Audi to begin with... I replaced the motor mounts on my subaru and other than hearing the starter more when starting the car it has been fine.

I see in a lot of old posts 2007-2012 Z1/Torque solutions/Avid offered a softer durometer bushing, specifically 60a vs 75a, does anyone know if anyone still offers these or should I stick with the factory trans mount and just do the Z1 motor mounts?

 

Also are there any bushings on the trans subframe mount or the front subframe? As I will be removing and reinstalling these.

 

Go with Z1 poly motor and trans mounts. NVH is not that bad vs the benefits they bring.
