Hey everyone, new to this page, wondering what the best mods for a 2009 Infiniti 37x with stillen exhaust and stillen gen 3 intake system would be?

Rear diff bushing

Aftermarket swaybars. IMO that should be everyone's first mod.

But like Lee just said... I bet your rear diff main bushing is shot on that 11 year old car.

And after replacing rear diff bushing, add a rear diff brace from Bellworks.

Well, if op races or tracks the car, if not a set of sway bar after that. However, I would say that op needs to replace the "gallery gasket" next after the rear diff considering the car is 2009. While in there, op should replace the water pump and timing chain as well if op wants to keep the car for the next...........100,000 miles lol.

Only after replacing the rear diff cover with a Z1 finned cover would the rear diff brace work.

The 3-point brace works with the OEM cover and the Z1 cover. The 4-point brace only works with the OEM cover. Either way, I wouldn't recommend it as next mod to the OP, although the low cost and DIY nature of this brace is appealing.

Whatever... the OP created his first post ever 2 days ago and never came back.
