I've narrowed it down to these two. Seems like they drop is about the same. After searching, it's sort of inconclusive, some say tein drops lower, some say eibach. Regardless, is there any reason to go with one over the other assuming price isn't an issue? Is one a better quality then the other? Seems stupid but i'm leaning towards tein because they are a japan product for a japan car....

 

Well Eibach has the million mile warranty. While Tein has a one year warranty on their products. I went with Eibach because they have been around a lot longer. And their suspensions are used much more in racing.

 

Eibach Pro lower's 1 inch Front and Rear (.PDF doesn't list Spring Rate)

Tein S-Tech: Lowers 26mm front, 25 mm rear (almost 1 inch) and has a spring rate of Front 5.3/296 - Rear 6.5/363

Pretty sure both are Linear springs.

I'm in the same boat as you, I hear progressive springs are your best bet (KGMM I believe are), but i'm leaning towards Tein since I like the spring rate (good for Ap1)

 

Eibach Pro-Kit springs are progressive while the Tein S-Tech are linear. I'd personally go with the Eibach springs, they are definitely going to be better in quality than the Tein springs, better comfort, and more than likely better handling. I hope you are ordering a set of aftermarket shocks to go along with these lowering springs.

 

But whats it spring rate? I need to compare numbers and cant find sqwat on the Eibach

 

There is a thread somewhere on here with spring rates, but i cant find it.

I have the eibachs and so far so good on stock shocks

 

Found the Thread, not sure if this is accurate today.

Ok well I bit the bullet and went with Eibach. Got them for $230 shipped off of ebay. Hopefully i'll receive them and have them installed by next week at the latest.

 

Where's the cheapest place to get the Eibach Pro-kit? BTW I live in CA

 

$230.00!
