Hi all,
A lot of other threads in this forum have mentioned the factory negative camber, bigger tire sizes, directional tires, staggered wheel setups etc. will cause tire feathering/cupping which in turn causes premature tire wear, loud tire noise so prevalent in G coupes and Zs. It seems like the only easy solution is to replace tires regularly.
Now my question is...will lowering the car further worsen this problem? I am not an expert in DIY camber adjustments, and do not have time and money to tweak the suspension...but the big factory wheel gap is something that I hope to get rid of (it makes the wheels look smaller... ).
So i am thinking to lower my G for the aesthetics of it, but if it will make me replace tires faster, sacrifice even more mpg due to negative camber, endure louder tire noise, getting 4 wheel alignment every 3k miles...then i will probably live with the shame of big wheel gaps
Again I am a car noob who daily drives the G (do not race) to go through the hell streets of LA with holes and stuff so please enlighten me on what I should do.......MANY THANKS!

 

Yea you will need to get a camber kit and so it can get aligned back into specs, I think that's if you do anything past a .5 inch drop.

 

It depends on what you choose to do. If you choose to lower it, you will need to buy your springs/coilovers along with a front and rear camber kit. Other than that, all you will need after lowering is an alignment and your tires shouldn't wear out faster than it originally did. As for tire noise, that depends on the tire you are running but I doubt it would change much either...

 

^^^^I agree 100%^^^^
On the other hand if he doesn't have the money or time he's better off leaving
the suspension alone and living with the tire gap. Springs and full camber kit
could cost inexcess of $1500 installed....something to think about!

Feathering/Cupping mostly comes from people who don't get their stock car aligned properly, and from people who think they can drop the car without a camber kit.

 

Thanks for the enlightenment guys!!
I do alignment every 6 months to monitor how the suspension is holding up, but I've done twice already and they said my alignment is perfect (according to factory specs) so I only plan to align it once a year now....
Ok I guess my next question is...is it true that you need a camber kit even if you just have wider aftermarket wheels?
I notice my rear is tilted outwards by a little bit (no matter how hard I look at it)...it has a 9.5" rather than the factory 8" and I am wondering if that is the reason behind the nagative camber~ I bugged the alignment guy to fix it he says he cant fix anything more perfect than a factory spec, and he says "sport coupes are designed with negative cambers for better handling"? Is that true or he was simply BSing me. I am worried the neg. camber will harm my mpg and speed due to increased friction
My suspension is bone stock by the way...

 

I wouldn't think you'll help the wear by lowering the car.
My 07 has sports suspension but is stock. I'll be lucky to get 12k out of the tires that came with the car.

 

my OEM tires from my sport suspension coupe got worn out after 5500 miles. i bought it new from the dealer too... my suspension was stock btw

 

Richard, there's no way you should have to get your alignment checked every
6 months. With the issues you're having I'd find a better alignment shop,
and someone that knows how to do the job! Be aware that the tires that
come with our cars (regardless of the brand) aren't ment to wear for ever.
Before you buy your next set investigate what makes a good set of tires.
The more knowledge you get the less money you'll be spending on worthless
purchases! Find out what all those numbers/letters on the sides of your
tires mean, it's worth while knowing....
