Performance dampener w/ swift springs

DJ-of-E

After using the "search" button, seems like shocks go bad after 25,000 miles of use?

These swift springs also recommend performance dampeners. What would constitute a performance dampener with these swift springs?

Swift spring were developed to work specifically with OEM struts you should get 50k out of your front struts.

Ive had springs on for almost 20k miles... Eibachs. And my shocks are just fine...

when they go bad I will get coilovers

Just a quick quote from the Swift SpecR description:

Swift made Sport Springs Spec-R is made for true track racing enthusiasts that wants to take their vehicle to the next level.
Sport Springs Spec-R is engineered with 2 main characteristics.

1 Redesign lowering ride height to maximize the suspension performance allowing the vehicle to fully absorb road condition for maximum traction.

2 Increase in spring rate to further enhance cornering speed through entry & exit. The increase in spring rate is based on the vehicle factory stock valving settings. Sport Springs Spec-R is increase to the optimal rate that the stock shocks can handle. Higher performance shocks are not required, but recommended.

So, you can go with coilovers and have the extra comfort of feeling safer (knowing that they were designed to work as a unit), purchase performance dampers, or just run the springs until you need dampers and get performance parts at that time. I say just run the springs until you NEED to change out dampers.............

For many of our customers that run a "performance spring" we recommend performance dampers. These can range from Tokico blue's to adjustable versions like KYB AGX and KONI Yellow dampers. For customers that are more street driven I would recommend non-adjustable as they are cheaper and you dont really need the adjustment for the street, but as for customers that auto-x(some classes only allow springs and shocks) and track, we recommend adjustable.

do you actually have koni yellows for our cars or are you just posting general comments?

corner3garage

I was just stating that generally we recommend upgraded dampers for our customers, as we have with the 350z's. Last I spoke to Koni the 370z Dampers are still in development.

yea like everyone says, swift designed their springs for the oem shocks... so they won't damage the shocks any worse than stock springs... though with improved handling you'll probably drive more aggressive haha, anywho they're in stock if you want them or need pricing

they are more than 20 to 30% stiffer in rate than stock. how do you feel if i give you 20 to 30% extra work load with no other compensation. it's common sense.

Red__Zed

got any of those available?

kenchan

cossie- im impressed with your explanation.

most people run 20-25mm spacers so that will reduce wheel rate considerably and lower the extra work load to maybe 3-5%? (just a guess)

which brings me to the reason of posting just like KamiSpeed... my 25mm H&R spacers are for sale in the for sale section. lol

slow work day for us both....

i am just cheap. even though i have never kept a car more than 3 years, but i really dont want to prematurely kill my struts/shocks unless i am doing other dumb things (like ice racing a prius)

Red__Zed

Why would spacers help?

basically like attaching a pipe over your breaker bar to get more leverage.

your wheel rate is the spring rate at the wheel instead of at the shell of the strut assembly or spring carrier in the back. the more you push out the wheel, the more leverage you get...easier to compress the springs so softens the ride.

for bound it makes it worse for the strut, rebound, makes it easier. there's give and take. usually people notice rebound undulations more, thus a lot of european dampers are only rebound adjustable vs simulateous.
