I search this on the board but couldnt find any straight forward good information on this. I need to know of the two, Tein or Eibach Springs, which is better?

Im not asking about kits or coilover's just straight springs. I don't want to steer away from the thread. Which is better of the two?

Thanks

My answer is only an opinion, but I'll go with Eibach. Prokits have a reasonable drop.

Questions to ask: What are the spring rates? Are they progressive? Will they sag over time? Do they look nifty with my color scheme?

They're both quality products, not hardcore, but quality. Remember to: buy shocks or you'll kill your stockers, look into a rear camber kit, get an alignment when you're done.

Hopefully others will chime in with their experiences.

I've "heard" from numerous people that H&R springs offer the same drop as the prokit (maybe a tiny bit lower) but have a much better springrate. They aren't any more expensive than eibachs, too. Just something else to consider.

I haven't had anything to complain about with my Eibach (pro kit) setup. You will definately want to do the shocks at the same time.

How long do the stock shocks last anyway with upgraded springs? Why wont they work with them?

H&R OE Sport springs or (preferrably) Hypercoils are the way to go, if you're willing to support them with proper shocks-- Illuminas or Konis. You can't buy them used, and they aren't popular names. Their spring rates are lined up awesome for a Koni setup. They're a popular swap into GC sleeves, running with Konis.

Why (skip if you don't care): Both are guaranteed from the factory to be within 3% of the advertised rate, and the springs are guanarteed to not sag. These come in 8" length, as opposed to 7", and since rates are additive, this is good. They also run the same ID as cars do on professional circuits. Helper springs can also be run in conjunction-- still learning about that.

Shocks need to be run with springs with similar rates. For example: toicy4ya has a 2g Spyder that has spring rates of ~245/150. I'm making the bogus assumption that the Spyder was given the same rates as the hatch. He'll think of running Eibach Prokit springs with rates of ~330/160. While his stock shocks were good for the previous spring rates, our forward rates are obviously higher now. He'll want to run shocks that are adjustable and offer a range of rates near those. KYBs or Tokico's would work.

Since these are lowering springs, upper mounts would be good to look into. Suspension travel is goodness.

In other news: Sean Caron and Dennis Grant took fifth and ninth respectively in the Street Modified SCCA National Solo this weekend. That's a great showing. DSM'ers had two in the top 10!

Edit>> How long the shocks will last is hard to say, but that they'll blow is inevitable. The shocks are no longer able to dissipate the energy as fast as the springs absorb it. That excess energy is spent with your shock attempting to close faster than it can. It can only take so many hits.

eibach cause it leaves you money to spend on other stuff.
