Few more upgrades are coming to the daily drive to make it more fun to drive and more of my idea what it should have been like from the factory.
1. Hotchkis Front Sway bar: I found a front sway bar on CraigsList for G37 AWD model that was made by Hotchkis. The bar is adjustable, and is about twice as stiff as OEM Sport package bar, and has two adjustability settings, so it will allow to play around with the balance. Here is the catch however: Hotchkis has two models for G37. One bar for RWD and one bar for AWD. I've compared the two, and the specs are the same. The only difference is that while RWD bar is perfectly flat, the AWD bar droops a little in the middle to clear some components of drivetrain in the front. Will AWD bar fit on a RWD model? I guess I'll find out.
2. K&N Cold Air Intake: The intakes on these cars are ungodly expensive, and especially the ones which are 50 state legal. Since I live in California, I didn't want to deal with swapping intakes every time I need to smog the car, so I was looking for K&N kit in particular, and I found one on ebay for about half of what it costs new. It's complete, and looks good, so I had no reservations about buying it. Once I install it, I will get the CARB sticker from K&N, and I'm pretty much set at that point. K&N has a dyno sheet where they claim between 10 and 14 rwhp across the range, so should be a pretty solid gain.
