just a little review after 8 months of daily driving my 08 g37s coupe 6mt with spl solid diff bushing. most people complain about these things being loud. i actually don't find them that loud compare to stock. but for me it didn't really reduce my wheel hop, most of the time i launch it between 2500-3000 rpm. not sure you guys (who has spl) think?

 

I think the bushings help but wheel hop can be caused by other things. If your tires are cold or stiff suspension? Also maybe look into aluminum subframe bushings.

 

Could you give a little more in depth review? Like performance increases, how hard the install was, also any increase in NVH?

 

^ As I mentioned, I didn't find much louder than stock and didn't reduce the wheel hop as much as I thought. And I've never track my car with it so I couldn't compare.... All install info you'll need is in DIY section.

 

Ok thanks

 

Any pics of the solid diff bushings installed?

 

Are these wort it over poly ones? Is it much of a difference on notice levels ?

 

There is at least one thread in the Review forum concerning diff bushings. While not SPL specifically, anything said about other brands will apply to the SPL parts.
