Finally, proper lowering springs specific to Si Coupe & Sedan - by Eibach

[JSPeruzzi]

Spacers really set off the stock wheels nicely.

Thanks man, I’m too cheap to buy the Rays wheels that I really want, so this will have to do for now!

I totally get it... I “settled” for my Konig wheels... haha. But kept my stock wheels for the winter.

I also want a set of Rays/Volks. In fact there’s a nice set here in the classifieds that are tempting.

What did you do to prevent the rubbing?

2017 Si with the Eibach Pro-Kit, Garage Line 20mm front and 25mm rear spacers. I rub in the front, splash shield area where the marker light is on the bumper. There is a small overlap into the fender that it rubs on if I hit a bump just right.

*stealth edit- I did not mod my bumpstops as per instructions.

What did you do to prevent the rubbing?

Nothing I can do really. It’s not causing any damage, so I just drive as carefully as possible.

Is it rubbing too when you have passengers?

What exactly does "mod the bumpstops" mean? Why can't the factory bump stops be used as is?

In the instructions that come with the springs, they instruct you to cut some millimeters off the bump stops. I assume it’s for shock/strut shaft travel clearance.

Yup. No worse with a passenger however, just over bumps i get a small scrape noise. I figured eventually it would rub the plastic off and stop making noise.

Would going with 15mm still rub?

I can't settle when it comes to my vehicle. why buy something and settle, when you know you want something else? That regret eats me up every time. I saw the Rays for sale in classifieds, and fight that urge to buy (translation: Wife would murder me, and part my car out.)

I assume you mean the spacer in the front? I would say no. Anything that pushes the wheel out from its original center would put it closer to rubbing.

I installed the springs last weekend, I can say the ride in normal mode is better while sport mode is about the same.

The progressive rear spring is soft when it needs to be and stiffens up when you push it.

There is a metal clanging noise from the rear when I hit speed bumps once in a while at an angle though. I can't chase it down for sure but I think the soft coils may be spaced too close to each other, and bang when I load up one side too quickly. I rechecked my work, but the rear is literally one bolt and nut each side to swap out the spring.

thanks for the feedback, I'm still deciding which springs to get on my Si, so this is helpful

Update to the metal clanging noise, turns out it was a loose end link. Somehow, a rock got pinched in between the swaybar and end link.

Also, got a rear seat review from the girlfriend. She thinks the ride is more firm than it was in my EF with OTS Ground Controls/Koni Yellow combo. I have to agree with her, at least from the driver seat.

Hey guys installed this kit on Saturday no sound over bumps etc now two days later I get a clunk sound when taking some bumps! But has far as I hear is only on the driver side!

What could be?

Double check to see if your sway bar end links are tight and in good shape.

Fender tab for sure
