OK - upon further inspection, I think that there is some credence to the rear looking a bit lower than the front. It's interesting - the gap between the wheel and the well is about 1/4-1/2 inch smaller than in the front. However, the rear of the car itself (distance from ground to sill) is about 1/2 inch higher than the front. This probably accounts for the appearance. Personally, my eye is drawn to the lift on the bottom and not the wheel gap - probably because I haven't taken the plunge into new rims and tires yet.

I really thought that I would be encountering more scraping than I actually am. Granted, I'm taking it slow over speed bumps, and navigating around curbs is an exercise in concentration, but so far, no scrapes. In my daily driving I deal with a lot of speed bumps, uneven roads, protruding manhole covers, and a fairly steep driveway. To my pleasant surprise, I haven't bottomed out on anything.

I bought my lip spoiler from Al503 after he sold his sedan and bought a coupe, who said he got it from a friend in Japan. It came pre-painted in brilliant silver and is a perfect fit.

inTgr8r - I'll take some pics from the rear tonight and post them asap. Let me know if there are any other angles you'd like to see.

Oh ya - one more thing. My boss is a big BMW guy. He's got a modified his 325i that he tracks quite a bit. I gave him the keys to my G and told him to drive it like he stole it. He took me on the White Knuckle Express around where we work and really opened her up. The car's manners are so nice now. It just stuck to the road like it was on rails. As he was driving, he kept chanting "nice car" over and over, though I could barely hear him because of the squealing tires and roaring engine. I'm amp'd!

Looks great;
If that lip's available in Japan, I'm surprized no one's marketing it here.
I think it would sell like crazy

Attached are some pics of the my G with the Sports package and G coupe springs in the front only. I did the coupe springs in the front because I wanted to bring the front gap down a bit to more closely match the gap in the rear. The gap in the front is 1.9" and the gap in the rear is 1.3". I recently swapped in the coupe springs in the rear just to see what it would look like. The rear gap is now .8". I kind of like the look because it's way BMW does their wheel gaps (barely any gap in the rear). I'll post up new pics when I get a chance. I must say the coupe springs lowered my car far more that I thought they would. The ride feels better than with the sport springs

If you have the base sedan suspension, the shocks would be the weak link.

I changed to '05 Z springs & went with Tokico D-Spec shocks.
These shocks are amazing.
It's totaly different car, great handling & a great ride as well.
inTgr8r, does the rear of your sedan sit lower than the front? Any rubbing problems with a rear seat full of people? This issue is the only thing keeping me from pulling the trigger on a new suspension. Thanks.

It's very easy to add rear ride height with these cars. During the rear spring install simply pull out the rear upper spring seats and install a round shim that is 3/8" thick or less depending on how much height you need to gain and put the rear upper spring seats back in place with the shims sitting on top of them. Either make them out of sheet lexan or polypropelene (the stuff that white plastic cutting boards are made of).

Here's my car on a 350Z H-tech drop with 3/8" thick spacers install in the rear.

Jim comes through again. I believe you have pulled the trigger for me, thanks. Jim, Infiniti should put you on their payroll. Your G looks great by the way.

No problem amG35 thanks. Look at what I just found

Just trim off the inner lip so it's flush and theirs a ready made 3/8" thick spacer.

I was wondering what your opinion is about the impact to front caster, by raising the rear height?

I may be wrong here, but isn't there a fair amount of caster in the front already?
I was under the impression caster magnifies camber during cornering.
& that too much can add to tire wear?

Is this why you say 3/8 or less?

Thanks..

Changing the front to rear ride height balance where the rear is raised more then the front will lesson front caster. Dropping the rear more then the front will increase caster. Oem caster is in the 7 to 8 degree range and is awfully high, but that's what they built this platform with. EVO350 has said they will be looking into making front arms that can lower front caster, but they have way to many iron's in the fire and too many races to run.

Yes, more caster does increase camber during cornering among other things.

The reason behind saying 3/8" max has to do with keeping the spring and oem upper spring seat in place and not allowing both to wonder off or out of the upper spring seat pan. With a 3/8" thick spacer in place, their is just enough of the upper spring seat pan area around the seat to prevent the whole assembly from moving out of place. Go thicker then that and you won't have that lip. Yes the pressure is upwards driven, and not sideway's, but it's just not something I would go past.

Here's a pic of the upper pan the the upper spring seat sit's in. For some reason the pic makes it look more shallow that it really is.

Thanks for the info.....
My bad; I guess I had the shopping cart wheel image in my mind (- cast)
It makes sense that the pivot should be ahead of the vertical axis (+ cast)

Thanks again.
