I have an '05 G35x with 10K miles on it. I am almost a year into a 3 year lease and am not sure at this point if I will buy it after the lease.

QUESTION: what would be the one modification you would suggest me doing. I would prefere something that is fairly easy and not extremely expensive. Keep in mind, everything is stock on this car.

I love this car but would like to "make it my own"

 

grounding gear

 

Wheels/tires.

 

^+1 Wheels/tires. I have the grounding gear and if I had to do it all over again, I wouldn't have gotten them (they help, but not much).

 

^+2 wheels and tires will make the care look 100 times better but can get pricey.

 

Leave it stock, just put some nitrous on it....make sure you return it at the end of the lease.

 

Which part of your car do you want to improve?

Exterior:
Wheels/tires

Engine:
Plenum Spacer

Suspension:
Sway Bars

 

I think the only way wheels look good is if the car gets lowered. Otherwise stock wheels with stock gap is the best combo, just my few cents.

 

lol...if it would last that long.

 

wheels and tire or ztube

 

Wheels, tires, and lowering springs. I consider all of these as ONE modification as I think they should all be done at one time.

 

I'd definately lower, then rims/tires, then pulleys/intake/exhaust.

 

I agree 100%.

Springs are a quick mod that can go back when you return the car and make it look way better with aftermarket wheels. My car was lowered the day before my wheels came in because I hate the way big wheels look on stock height cars.

 

what's a ballpark on how much it would cost me to have my g lowered? and this is something that could easily be changed back if i werent to buy out my lease?

yes i am extremely new to car modifications

 

Depends on how you do it. If you go with z springs and do it yourself it will cost you around $90 for the springs. Car can easily be returned to stock later.

I am not sure with other aftermarket springs but would guess the springs would be $150-$200. If you don't install them yourself that is where it could get costly (i.e. another $200-$300 or so I would guess for labor).
