Improper spring installation warning

Oh, I didn't take it that way. No worries. I just used your post as an example because I want people to know things like motion ratio, shock limits, etc when using a lowering spring.

1.4" drop blowing stock struts is no surprise, especially under heavy use.

Surprise to me. I ran crappy Skunk2 springs on a Mazda 3 stock struts for 80k miles without a hiccup. It settled to be about a 2.5" drop

I will soon report to all of you but I'm at 2000 miles mark with stock springs and my girlfriend told me our Frs now feels like her civic when she had Monroe shocks( no one should ever to this, I got to replace them for KYB shocks 1 year later) so I will see with my dealer what they can do about it before I install my Tein H-TECH... Even the VSC is engaging since the front end is too soft... So don't put the blame on eibach that fast, you should remember this car is a subaru with all the reliability problems that come with it...

Unless tirerack sells fakes....

They show them as available next month. As far as I know Sportlines haven't hit the streets yet outside of the prototype car(s?) (Pekingduck, and others?) who is now on coilovers.

More details of how the OP's friend "busted" his factory shocks and got a set of Sportline springs before we even manufactured them would be great.

The PROKIT were bought off of Tire Rack. He got them specifically for the FR-S and does have the reciept and pictures of the box as well as picture of the car.

He is sending them to my email and I will post them ASAP.

Shocks are leaking bad.

And now that I think about it, his kit sure as hell sits a lot lower than a Prokit should. Its about where a Sportline kit would sit :p

That makes more sense that it's a Pro-Kit and not the Sportline. The Pro-Kit is a 1" drop and our engineers say there is no way that our springs would cause the factory dampers to leak.

What happened? There's a couple of things. I'm by no way discrediting your friend or Toyota technicians. I am simply posting this information for others to see so they do not make a common mistake with installing our spring kit or other spring kits.

We found out the hard way that if you zap off the factory top nut with an impact gun that you can actually spin the shaft internally causing it to click. If you spin the shaft too far this will cause the shaft to come disassembled internally and could, over time, cause the shock to leak. There is a special tool that needs to be used to lock the shaft from spinning when assembling and disassembling the front suspension.

If the special tool was not used and something else was used to hold the shaft, this could cause scoring on the shaft that could damage the internal seals, thus causing the damper to leak.

Has your friend called Eibach directly so our techs can help diagnose what is going?

I will say the car does ride a lot rougher with those springs. They are not anywhere near as friendly going over bumps and stuff as the factory ones.

Are the sportlines going to be even rougher?

Or is this again a problem with his shocks?

Truthfully Toyota has guidelines for shocks and if a tech replaces them and its not within the guidelines they will charge the dealership. Now unless he has a cool ass manager that doesn't care, then he is good. It has to be leaking all the way down and all around with stains on the shock housing.

They are replacing them from what I understand.
