there isn't much you can do performance wise besides the basic bolt ons, which realistically you are probably gonna do anyways. I think you should do appearance.. Image is everything!

 

I haven't touched the car's engine bay. I've focused on cosmetic mods for now, and perhaps up the power slightly in the future for a little more pickup - the 250 is way under-powered haha

 

My vote is for appearance. This car is probably one of the most aesthetically appealing cars when modded compared to other cars in its class.

Performance mods are pretty much suspension. So unless you track the car, the significance of your suspension mods will not be felt from daily driving.
The HP increases on this car are marginal, given HP per dollar spent, you will have to determine whether the cost is worth the gain.

 

I did a little of both too.....wheels, roof spoiler, spring drop, f sport sway bar, tanabe exhaust and f sport intake.
So a little appearance with the wheels and spoiler and drop, then a little with the performance, and springs, sway bar, exhaust and intake.
A balance of both.... Some things accomplish both choices too.. the springs and struts are both performance and appearance related , as it handles better with a lower center of gravity and the car looks better with a drop.....then the exhaust helps performance and looks far better than the stock setup.
