I would go ahead and invest in both. Even with a mild drop I wore my tires unevenly up front when I decided to forego a front camber kit.

When the springs settle over time you will be glad you did

Good looking wheels, now you just need those Sport brakes for all that empty space in there!


I installed my S-Tech's last week and am letting them settle in for a week or 2 before I get an alignment, otherwise you'll just have to do it again. I'm going to install my rear camber bolts and see what the readout shows. I have a feeling the front is going to need the control arms as well. Tein's are pretty damn low lol

Seems like lowering the vehicle is a huge investment. Other than appearance, what benefits does lowering have? Is the ride handling significantly improved? My other option is to save some more funds up and install air suspension which has a lot more room for adjustments

Also,

These tires I purchased are very sticky and grip the road like no other lol. With the addition of my Cusco strut bar, turns are easy to maneuver now

I solely wanted to lower my car just to rid of the wheel gap and look more aggressive. The main point is to lower the center of gravity closer to the ground and helps with body sway, in turn make a more responsive car. Usually minimizes under steer and helps with aerodynamics since there will be less air under the car from wind drag and more air on top of the car pushing it down towards the ground. These are all reasons why every sports car ever is as close to the ground as that marketed demograph can handle.

Sorry to tell you this, but air flow over the car is worse than that flowing underneath. Cars have the general shape of a wing, so as you move the body develops lift. Lift is bad, m'kay?

Lowering does indeed reduce airflow underneath, which is pretty dirty due to all the mechanical bits poking into the airflow.

The biggest aero benefit provided by lowering is in reduced frontal area. Frontal area x coefficient of drag = total aero drag. We can't do much for cd except tacking on spoilers, lips and wings to the extreme ends of the car and they general INCREASE total drag due to induced drag. So, reduced frontal area FTW.

They look great man! And will look even better after the drop!

steven92

Thanks and they're easy to keep clean as well lol

Hmm may just save up and get air suspension. Then, I can raise and lower the vehicle when winter or speed bumps come my way with ease

Are you talking to me? If so, why are you agreeing with me in just a more douche-y way? I literally said it lowers the center of gravity and reduces the wind underneath the car..

so basically may increase handling and improved MPG is what I got from all that scientific mumbo jumbo

^^ I wouldn't go as far as MPG's but that would be nice, he googled something and pasted it, whatevs.

steven92

Yeah the moment of inertia is lowered

Yes, I was. In particular, your statement about more air going over the car pushing it down. It won't push it down, it generates lift.

Hmm maybe I had it confused but I was taught to follow the Venturi/Bernoulli rules. Air accelerates as it's confined and pressure drops as it accelerates. On older 70's 80's cars the aero was trash, heck they even had some cars with fans underneath to help, checkout the Chaparral 2J for example, its too bad they were known to catch on fire lol... I wouldn't think it's very likely the style and lines of a modern car will have any type of lift, especially on a sportier G37.

It's too bad we don't have the megabux to throw our cars into a wind tunnel with rolling floor to measure up/down force like the race teams do.

Air dams primarily divert air from under dirty cars. Flat-bottoms and tunnels would change that reasoning. While makers now pay attention to underbody aero, it's still lumpy and bumpy under street cars.

And your understanding of Bernoulli's principle is correct. However, air going OVER the car isn't confined.

[edit]And I think we might have a frame-of-reference difference?
