Lowering may cause negative angles of 4 wheels in an yea

[jhw0813]

Hey, guys. I have a '06 g35 coupe 5speed auto. It has about 35k miles. The second owner lowered the car like 2 inches 1 year ago, and the first owner set aftermarket rims up. When i got the car the four wheels are all negative angles. I currently put the used four wheels and tires that are Nissan rims and snow tires. Today i let a mechanic to do alignment to correct the negative angles of the four wheels. After he took a look at it, he said that the wheels became negative angles because the car is lowered. So need to replace some parts to correct them. I listed below the parts they suggested. I'm trying to find the parts, but i don't see any name match exactly. The car has no problem i feel at least. I just wanted to correct the negative wheels to save my tires.


C Alignment Adjuster Control Arm * 2 = $190.74 + $45(labor)
C Alignment Adjuster Kit Rear * 1 = $875.44 + $70(labor)
Alignment Service - Exotic = $119.99(labor)


44624 R Disc Brake Rotor * 2 = $59.99
PD905 Organic Disc Brake Pads * 1 = $119.99 + $84.99(labor)

373K4 Poly-Rib Belt * 1 = $39.99
463K6 Poly-Rib Belt * 1 = $48.99 + $49(labor)
------------------------------------------------------------------------------------------
Total: $2,245.47

Help me, people. I don't know what to do. It has powertrain warranty and bumper to bumper warranty, but they don't offer service because it is lowered.
What will be the best way for me? I have a bad experience with that mechanic shop before, but i had no choice except letting them to do alignment, because there are just 2 shop alignment available of this town.

Here is my point. I don't want to tune up, and i don't want to be rejected by dealerships when my car has a problem which is covered by the warranties. Howere, if the cost to get back into the warranties' boundary isn't that much higher than the cost to correct the negative angles with a way not to hurt the car in the near and far future, I would just go for the way to warranties' boudary.

Here to below is what someone replied my post.

This is an easy solution. you need adjustable camber arms front and rear, with rear toe bolts. One of our sponsors, THMotorsports, has a good deal on them. SPC Front and Rear Camber Kit for $520.

Get them installed and get an alignment set to close to zero degrees. If the alignment guy puts the alignment within specs, then you still may have worn out tires on the inside. Within specs is an entire degree of difference.

Are the prices you listed above from the dealer? Those are crazy prices, except for the rear rotor.

You can buy both belts for $40 and install them yourself with a few tools. You can get brakes pads for less too.


And i replied to his answer like below.

The cost is not from a dealership.
I have three question.
1. If i mean to higher the car back to the stock height with stock springs in order to get warranties services, are the parts you suggested still necessary to be set up to do the alignment to correct the negative angles?
2. Is it possible just force to set the wheels to close to zero without the parts the mechanic suggested? Will it cause problems to my car?
3. Are the parts i listed and the parts you linked above the same parts?

And he again.

1. If i mean to higher the car back to the stock height with stock springs in order to get warranties services, are the parts you suggested still necessary to be set up to do the alignment to correct the negative angles?Stock springs will put the car back to stock height and may solve the camber issues. However, the stock springs may not completely solve the problems with the inside tire wear because that still happens with negative camber.

2. Is it possible just force to set the wheels to close to zero without the parts the mechanic suggested? Will it cause problems to my car? You cannot just force the wheels back to less negative camber.

3. Are the parts i listed and the parts you linked above the same parts? I don't know if the parts I linked to are the same as the parts your shop wants to use. The parts I linked to - the SPC camber kits = are IMO the best on the market. And they are less expensive than the parts your mechanic wants to use. I have them on both of my Gs.
Also, your bumper to bumper warranty is about to expire, because you have an '06 model. You will still have some powertrain warranty though.


I want to hear people's opnion. And What i asked in the third question is if the parts(SPC Front and Rear Camber Kit) are what i need to set up to collect the negative angles like the mechanic said and suggested.

JHW,

Would you considering changing the spring altogether? I came on the post some info about my recent installation of Tein H-Tech 350Z springs, which went quite well after I did quite a bit of research.

Long story short, Nissan Sport Tech folks made me aware that a .8 or less drop will allow for alignment to get backto factory or mfg. specs.................and that's what got me to choosing the 350Z springs.

And, I'm gonna try to alignment results that show the camber, caster, etc. getting back to normal. This is with 20x9.5 wheels/275-30Z420s in the rear and 20x8.5 / 245-35ZR20s, front.

I'll be back. Hopefully I can copy/paste some data from cardomain instead of retyping.

Here you go, JHW, the data from........next post - camber results (if possible; it's a PDF).

BTW, the entire job cost me $600.00. A steal if you ask me. (Springs $400, Labor $150, Alignment $50)

Not to mention I've had the car since Nov. 2006, i.e., I purposely waited until the 4 year warranty was just about expired to really start the aftermarket stuff. (It's just a Monday-Friday daily driver; only about 24,800 miles thus far.)

Anyway, that way I don't have to listen to any of that "voided warranty" bulls...........never mind. But, it's on now.

Gonna try to up my performance and better my front-rear balance by losing some weight in the rightp laces.

Maybe upgrade the shocks, although not an absolute necessity due to spring rates not drastically changing with the Tein HT 350Zs (and for about the same price).

Then, come the power-adders under the hood.

Whatever you decide, good luck.

********************

2006 G35 Coupe Spring Rates w/sport suspension:
FRONT: Same spring rates as stock - 314 lb.
REAR: Spring rate increase of 24% - 427 lb. (from stock 342 #)

So, after doing alot of research and in the interest of 1 and 2:

1) Not wanting to need a camber kit for more than a .8 inch drop to get back to mfg. spec, and
2) Wanting to keep spring rates as close as possible to sport-package or sport-tuned suspension spec.........

My next mod:

TEIN "H-Tech" Peformance Lowering Suspension Springs 03-08 Nissan 350Z

Spring Rate Front: 358 lb./inch

Spring Rate Rear: 375 lb./inch

Ride Height Lowering Front: 350Z - 0.3 inches (7mm) / G35 Coupe .08 inches

Ride Height Lowering Rear: 350Z - 0.2 inches (4mm) / G35 Coupe .07 inches

(Will post pics when I'm done.)

********************

AUGUST 2010:

Had Tein 350Z "H-Tech" Springs installed a few days ago..........pics later.

Alignment went back to within manufacturer's spec or acceptable range,no camber ket needed.

Springs seemed to have settled, and while noticeble to me - especially from behind the wheel, the drop is barely noticeable to the untrained eye.

Whatever.

Bottom Line: Now I have a PROPER sport package, and the lower ride combined with my Rear-Active Steering, the BMW 3 - even this generation - is beatable at all times. No more weaknesses in my setup to exploit. Brang it onnnn!!

Not to mention, I don't know what Nissan-Infiniti engineers were thinking when they decided to only up rear spring rates in the sport-suspension package, but who cares?

Rides better, handles better, accelerates smoother w/less drag (duhh!), no noticeable negatives regarding the different spring rates, etc........yet.

I've heard I may get more body roll, but haven't driven it hard enough to notice.

Again, whatever. I'm good!!

NEXT MODS:

*Tokico HP Blue Shocks/Struts

*SEIBON OEM Carbon Fiber hood (from my research, saves about 20-22 lb. from stock bumper)

*K&N Cold Air Intake & Air Filter

No dice, "brother" (I think)............PDF won't post.

Yo, email me at the following if you wanna see the data. It's for an '06 5-speed auto Coupe just like yours.
