Replacing stock springs to lowering springs with stock struts

[kuhan]

Do you guys know that if you replace your stock springs with lowering springs, your stock struts will wear out much faster than normal? Suggestions: if you are going to replace with lowering springs, you should consider replacing your stock struts as well.

Quote »For every action there is an equal and opposite reaction. The strut is design to dampen spring motion. It's valved for a certain stiffness spring. When the spring is compressed by a bump, and then it rebounds, the strut slows it down.

Now imagine what happens with a stiffer spring. Cars hit bump, spring is comressed... what happens when you compress a stiffer spring? It rebounds in the opposite direction with equal force... ie MORE force than a stock spring. That extra force is transmitted directly to the strut, and if it's handling more force than it's designed for, it will heat up more and wear faster.

Yes, Yes, I did.

IIRC, someone posted a little bit ago that Tein is/will be developing a fully adjustable set up for the A/C also, so thats one new set of struts right there (if it ever happens)

[dldjros69]

Any merit to this?

Will i get atleast 5 years out of my current struts?

All very true but the Eibach Proline Springs were designed to work with your OEM Stock struts/shocks. I believe generic had Pro Lines on his last ride and they were still going when he sold it. If you got a lower drop than the pro lines than yes I would replace the shocks and struts with KYB AGXs

if you drive normally you won't ever notice the wear. if you race at the track then you'll notice soon enough

Now I am gonna have to order the springs for sure.....thank you very much for that informative post, if you ever have questions about computers, I would be happy to return the favour.

mcheddadi have you ordered the eibach springs?? The best price I have gotten for the springs here are 320$ (local shop) And about 180$ for installation. I know the stillen group buy is about 200$ but I do not think they ship to Canada, and trying to figure if they do what the added cost is, and if we are gonna get raped with duties. I think its time maybe I take a trip down to the US....

[mcheddadi]

Stillen does ship to CanadaShipping is 65$() with UPSPand with the GB price total is 254$ shipped to Canada

Looks like there is another 41$ duty charge, looks like its gonna cost use Canadians 294$. We are paying 100$ more even though we have an even dollar. I wonder if there is a Canadian shop that can do better then 300$.

Ok just to give you a heads up here is the link as to how I got that amount; UPS Duty Charges

[mcheddadi]

I don't get how you got the 41$? and it's shipped with UPSP not UPS

[spockrock]

OK my mistake sorry its late and I have a cold, but from what I can gather there is a 5$-8$ fee and applicable taxes, so for me 13% and 12.5% for you, if I am not mistaken.

So at 254$ at 13% is, 33.02, and the 8$ fee brings the total to 295.02$

That is of course under the assumption if the shipping charge will be taxed as well, worst case scenario.

Thanks for the update. You should really read previous posts about the springs before you make threads like this... the Eibach Prokits are desgined with progressive rate springs. These springs allow for a natural ride comfort and strut life. No need to get new struts with the prokit.

Dude, I only live 6 hours away from Canada. My son goes to school in Erie. If you want, you can have them shipped here and I can give it to my son and you can pick it up from him there and get it installed in Erie PA also...Just an option if you feel the shipping to Canada is too steep. But with the price of gas in Canada and US, it might be cheaper to have it shipped to you. Your choice though.

Its very nice of you to offer, but you are right the gas cost in the 3.5 would def be more money, prolly the same result if I did it in the 07 Camry, and that thing has awesome gas mileage. The trip to PA would be around 8 hours, nah I am just venting that we (Canadians) end up paying more for everything even though we have a dollar thats nearly on par with the US dollar. I am sure if I keep looking I might find a place that might have near us dollar prices.

Glad to hear that, had me worried for sec..

You should be fine on the stock struts. While they wont last as long as they would with the stock springs, you don't need to replace them along with the springs. My brother has 32,000+ miles on his 350Z with the Eibach Pro-Kit springs and stock struts, and no problems. On his Lexus IS, hes been running a 3" drop up front, and 2" out back for about 20,000 miles so far and the stock struts are fine.

[kuhan]

so you guys are saying that I can running these lowering springs on stock struts and i don't have to worry about these struts for the next 30,000 miles or so?

[windhaven]

I guess that is what i'm reading.

[kuhan]

Alright. I'm sold. I will take you guys' advices. much appreciated!

[EzeebMOS3]

Haha what happens after 30k miles? i was planning on keeping mine up to or over 100k miles...

[kuhan]

that's when your car becomes a (literally)

[adidas2go]

The average life of Macpherson strut is about 70k miles. Average viewed strut life lost due to lowering springs, 10-15%. Therefore a good estimate of your strut life with the Prokit is 55-60k miles.

[EzeebMOS3]

Hmm thats definetly convincing....

Im just worried about the winter/pot holes here in the Boston/ NE area....I'm also thinking about getting the stillen lip.....

Do you think that id be alright with the drop?

Also doesn't the sportline drop the car less?? How come people are just getting the proline?

I think you should be fine, in the winter, I am getting these put on my car soon-ish. The sportline drops the car even more, and the sportlines are not available.

[adidas2go]

Well, first of all everyones getting the Prokit, not the Sportline. Also everyone is getting the Prokit because the Sportlines' aren't made for the coupe. You'll be fine with the Stillen lip because I have the entire fascia and I only scrape in extremely steep drops. I think I've only scraped like 3 times in the last month of owning both the Prokit and Fascia.

[johnny_d]

you're mistaken, Sportline series drop the car much more than Pro-Kit. Eibach already said they won't make Sportline for the A/C because it sacrifices too much ride quality. The Stillen lip isn't much lower than stock so you should be fine
