spring rate :: eibach pro-kit

is the spring rate in tha pro-kit made from the speed3 that much stiffer then that made for the 3?

im currently running a pro-kit on my 3 w/ upgraded mazdaspeed sways(f/r) & im still rubbing alil in the rear... so i was woundering if i could upgrade to a set of Speed3 (pro-kit) rear springs... if that would fit the problem @ hand...

some1 help me out here... thanks

The last ime I checked, Eibach told me that they have no plans to sell a speed3 specific pro-kit in the US.

Re: spring rate :: eibach pro-kit

if you are running 18s, you may need a stiffer spring to prevent the rubbing (for that lowered height).

I don't think the Mazdaspeed springs are any stiffer.

thanks... -- thats what im looking to do...

i dont rub when cornering...

only squats alil @ high speeds if i hit a dip in the highway.... -- just barely rubs... enough to make a noise.. but not enough to do anything to the tires...
ive had the wheels on for a month.. no tire issues thus far...

Re: spring rate :: eibach pro-kit

You may also want to consider a set of shocks/struts instead of springs. Koni yellows made a significant difference in how flat the car handled, even with stock springs.

Re: spring rate :: eibach pro-kit

I've sampled a number of suspension setups on my 3 and found that shocks/struts have a larger impact on ride "stiffness" and also that rear stiffness plays a significant role in ride quality. O

Re: spring rate :: eibach pro-kit

yeah, I will also be running stiffer rear springs than the front.

KYB only makes the GR2 dampers right now. NO Gas-Adjusts and NO AGXs.

However, Tokico is making dampers. They should be out soon- hopefully.

Re: spring rate :: eibach pro-kit

or you could run koni yellows and set the rears to the stiffest setting and the fronts to the softest.
