The title pretty much covers it. ****ty road with massive constructions around lead to both my front wheels bent. Maybe I'm a ****ty driver myself. Either case, I did a little reseach... My ride (05' G coupe) currently running on stock suspension:
Oem linear springs
G35 coupes 2005/2006 with oem 19’s only
350Z 2004.5 to 2006
Front:314 Rear:427
Would you think by changing out the springs to the Eibach progressive would help? By replacing the front to a softer progressive rate spring yet keeping the rear stiff. Could this reduce the chances of bending the wheels over and over again? I know some would say, just drive careful. But there are times it is just unavoidable... Let me know what you guys think?
Also, any other springs out there has a lower fr rate and stiff rear that doesnt lower the car that much (inch & over)?

Eibach G35 Coupe progressive springs 1.1”/1” drop on G35 coupe
Spring rates in LBS initial/final front 229/337 initial/final rear 274/463

Another suggestion is 40 profile tire for the front? Would that be ok? 245/40/19? while keeping 275/35/19 rear?

 

I can't follow the logic that a tire, even a 30 series sidewall, would transfer enough energy to actually bend a wheel without shredding the tire in the process. You didn't say what size tires you are running on the oem 19's but I'm guessing that they had to be rubber bands with no sidewall to actually bend your wheel on any road unless the sideall is literally folding up under pressure due to low inflation etc. I have OEM sport shocks on Z springs with the same rates you mentioned, with 40's all around and I drive it hard on some really bad roads (you should see the roads here! torn up concrete with huge chunks missing, uneven RR tracks etc.) and have never had an issue with any damage.

So what are your stock tire sizes? I've never heard of anyone bending an OEM 19 without the wheel coming in contact with the curb or another non forgiving object. So how'd you bend your wheels?

 

Thin sidewall tires can lead to bent wheels. Think of shipping a fragile item, which is better protected from breaking? The one wrapped in one inch of paper, or one wrapped in two inches of paper?

Based on my own experiences over the last three years using four different sets of springs (three aftermarket and one stock set) on my 05' coupe, I must say that going to a softer than stock spring on these cars is really BAD idea!

Linear or progressive, lowered or stock, it doesn't matter, softer spring rates are a bad idea. The G is a low heavy car, with limited suspension travel. The stock springs are a compromise of handling and comfort. Going any softer (and God forbid lower) leads to a horrible ride and handling. The car is too heavy, and the suspension cant control the car. You will be driving on the bump stop all day. Going lower with a higher spring rate has its problems as well, the suspension can handle the weight of the car, but you lose precious suspension travel. Its all about compromise.

My suggestion is to look for springs that are right at stock rates or slightly firmer. I eventually settled on 350z Tein H Tech springs.

 

It seems that you should be making a claim against the city and construction company.

 

Its aftermarket 19x9 front(245/35/19) 19x10.5 rear (275/35/19)

 

Well I'm here to tell you otherwise. I have had SIX bent rims on my sedan. ALL of them Stock Infiniti rims. Four of them were sedan 18" sport rims, two of them are M45 sport rims.

It's very easy to see why. Look at the attachment points for the "spokes". They are on the outside of the rim. That leaves 7" on the 18" and 8" on the 19" rims for a "leaver" to bend the rim on the inside when you hit a pothole. That's where most of them get bent, on the inside. The reason old "Mags" on a hot rod never got bent is because the spokes were attached to the center of the rim. That gave much more support to the rim itself.

BTW, I was running 45 series on the 18" and 35 on the 19" rims.

 

So you're saying drive an oem 18" equipped car off the lot and hit the standard pot hole hard and you'll bend your rim. It's done probably a few thousand times a day statistically. Love to see that youtube video........you should make us one and post it to the forum.

 

Sh*t happens and some people just have bad luck (ex. myself). That's besides the point...
From the limited reply, i suppose replacing the springs with lower rate would not make an impact on bend wheel? At the same time, it reduces handling?
Please let me know, I'm frustrated.

 

First of all there is no "standard pothole" here, I don't know about where you live. Most of them here are 6-9" deep and 2-3 feet across.

Second, the guy here that fixes aluminum rims told me that he just "camps out" at the BMW dealership because those guys come in daily to get their rims fixed.

So yeah, an OEM equipped car off the lot had FOUR bent rims in less than a year and a half. Now I have two more after having my M45 rims on for less than 8 months.

The roads here are teh suk.

 

6-9" deep, 2-3 ft across... that's a pit, not a pothole. How can you not see those things? I wouldn't just dent a wheel in one of those...

 

We try to dodge them, but sometimes you miss.

I have been in Houston and hit road transitions in constution areas that sent me out of my seat. I know there was a 4" lip of concrete that stuck out right in the road.

 

That's not that bad... that's only an exhaust, maybe front lip and maybe the front bumper, shifter and a bad scrape across the bottom of my car.

 

I'd say you are cursed and had a voodoo spell placed on you or something. 99.99999999% of users here and worldwide have never experienced this and never will. Hows the rest of your life?

 

Nuttin' but curb rash.....

 

I bent my front right OEM 19" rim on stock rubber. I got the tire/rim warrenty so they should replace it for free. i already used it to replace two tires. one was the original tire, and the second was an after market, upsized tire.
