Default Springs on stock shocks??

Other than a more harsh ride what are the major downsides to running aftermarket springs with the stock shocks, ive read that it will cause your shocks to die on you alot quicker, just looking for everyones input thanks

the stock shocks are not engineered to be used at lowering spring ride height... the more the springs lower the car the worse off your stock struts will be.

eibach pro-kit and prodrive springs don't lower much and usually are the best for stiffer springs that still take it easy on your shocks.

you should also look into some after market struts if you don't want to break your stock ones

i rode on stock struts and tanabe springs for awhile, it's fine. as long as it's not more than like a 1.3-1.5 in drop your fine. look at sti pinks, made for stock stuts and give about that drop..

Prodrives are great, but they are underdamped by, say, 15-20%. If you push hard you will notice, otherwise, you'll be satisfied.

struts are a consumable. lower, stiffer springs will just make them wear out quicker, but it will still be gradual. i expected a much harsher ride from the prodrives when i put them on but i was really surprised by how much civility the springs maintained. theyre not harsh at all but left to right and vise versa lateral transitions were much quicker, flatter and controlled. front end dive and lift were also cut down. until you ride in a car with springs and aftermarket struts, you wont really know what you are missing by just replacing the springs. i put in my prodrives at around 50k and then added koni inserts around 62k. the ride was smoothed out lot by the konis but by far the greatest difference the konis made for me was the first time i did a track day with them. most of the spring reviews that you hear about that really diminsh ride quality are about springs that provide a large drop, not stiff springs with underdampened struts.

I've had my stock struts and tanabe gf210's on my 03 wrx sedan since july 04 and the ride is harsher than stock but hopefully the stock struts will last for a while. Plan to upgrade them, definitely.

If money is tight, like for me, buy the Prodrives and use em on stuck struts. Wear the stockers out, why waste them, it is not bad at all; when they are gone, upgrade.

Otherwise do them together. I like them a lot. I kind of wish I did not have lowering springs, even though the Prodrives are not too low at all. I just think it is a shame to waste the long travel suspension Subaru worked to develop. I am kind of interested in STi wagon struts with STi springs now, but that is just me. Mainly I just want good damping. The stockers get a bit floaty and have some wierd motions in transitions sometimes, but only when driving hard.

just for the record.... i have tein s-techs on an 04 stock struts (2.4" drop ) and my struts were wasted in 8k miles. Creaky, harsh, and really sucks now. Don't go for cheap and don't go for low.... you'll hate it in the long run.

Damn, good to know. I was gonna buy Tein S Techs to go w/ my stock shocks, but now im having second thoughts. Should I go with the tanabes then? I will not change my stock shocks for now unless I find a killer deal on them.

Don't get the H-techs either, the spring rate spread is huge, as it is in the S-techs, and very imbalanced I think.

Get Prodrives or pinks. Search for Prodrive and see how many favorable comments there are: more reviews and favorable comments than any other spring, x100. Why would you pick anything different? Yeah, they may be $100 more than other springs, but you paid what, $18,000+ for your car, and next to tires this will probably influence your handling the most. So why cheap out on a half-assed spring? I saw a set of Prodrives for $100 or something ridiculous in the SCIC forum. So deals can be found, with patience.

would the teins hold up if i replaced the struts to kyb's? or would they kill those struts too?

kyb wont warranty their struts if you use a spring that lowers the stock ride height more than 1.5". imo your better off spending more money on koni inserts and getting a lifetime warranty as well as infinte adjustability. they should be the last struts you buy. www.alexperformance.com has konis for $555 shipped.

another reason that i like the prodrives is that their spring rate is linear. as you progress into a turn you dont have to wait for the cars weight to transfer and compress the spring into its stiffer zone like in a progressive style of spring. handling is predictable and responsive.

If you are looking for something to go with your stock shocks, you cant go wrong with Eibach imo...

Provides a decent ride, lowers the car a bit, and you still get considerable life out of the stock shocks.

so koni's would work with a spring that goes more then 1.5 and they would warranty them if anything happens to them?

Trying to slam an Impreza gives bad overall results.
Period.

The key is NOT going too low, because giong too low will kill ANY strut more quickly and result in a poor handling vehicle that may actually be very dangerous to drive in a 'spirited' manner.

If ya really think ya need to drive a slammed car, a WRX 'aint it....get a hunduha.

Teins have something like a 60lb spread between front and rear, 140/205, or something wierd. I can't be bothered to look it up.

When I had them on my car, the rear felt all plush and the front was jackhammering over bumps and bottoming out all the time (several times per day). The rear felt like it gripped more because it held the road instead of bouncing and bottoming out.

It felt like a seesaw, too, with each end doing something different. Stupid springs.

Prodrives get your car lower, leveled, and have a linear 175/175 or 180/180 or something.

as long as you dont tell koni you are using them in a racing application they will warranty it. just like many other warranties you have to be the first time buyer so if you value having the warranty you must buy new and have a reciept. the struts will handle greater drop than 1.5". they are much more effective when they are able to use their full stroke, but they shouldnt suffer the wear that the agx's do.

I don't mean to sound like a jerk, but if you've narrowed your choice to Eibach or Prodrive, you haven't finished the decision making process yet. They are both good springs, but they are enough different that you should know why you selected one over the other. The remaining question is basically overall smoothness/comfort vs. better handling when driving quickly.

I think the quote above is worth reading again. For balance, Eibachs give a more comfortable ride under "normal" driving conditions.

My $.02, and $.02 borrowed from abaxter34.
