Question Tein HA suspension [pro's and con's]

My 2.5 RS is one week old and I'm looking to upgrade the suspension soon. There is a group buy for the TeinHA setup and it struck my interest since i was considering that option.

Can someone give me objective advice on this topic?

My I'm in New York and I have to drive into the city every day in my Impreza. As you know, the roads are a mess. I think the stock suspension is way too soft and wooshy (if there's such a word) and i've had experience with tokico's sport shocks and H&R springs on a car with poly bushings all around even engine mounts so i know stiff. But I want to find a nice low ride with a good compromize.

So i was thinking of the adjustability of coil-overs so that i could tweek and tweek until i found the right setup for everyday driving and fun. I know, I know. This sounds like a stupid reason to buy such an expensive setup. But believe me, I'd rather pay the extra money now and not have to change my setup later (i think).

If there's a way to quantify stiffness and ride confort and NVH with the Tein HA setup, what would that rating be?

Does anyone recomend something else knowing the crappy NYC roads?

Any help will be greatly appreciated...

I know that the Tein HA kits Imprezer orders come stock with 4kg/mm (that's ~400lb/in) springs in front and 3kg/mm springs in rear.

If I were to give an opinion it would be that's too much spring for daily driving on rough roads. Even if you could endure it, your wheels might not.

Wait, forgot that TEIN (and others) offer a variety of alternate spring rates but I don't know if Alex can get the kits with anything besides 4kg/3kg.

Thanx for the quick reply ColinL...

That's what i was afraid of... Ultimately, what i want from my suspension is:

1.) Better cornering and feeling of security at higher speeds.
2.) A lowered stance (yes... I admit it... that one is more about looks but stability improves at the same time)

Also. I know very little about coilover suspension so i was under the impression that you could adjust every aspect of the ride, even the "harshness - softness". Am I wrong on this? From what you say, it seems to be set with whatever springs you get... is that right? Are the springs made so that as you lower the car, the spring rates don't change?

Please excuse my inexperience on this : )

Colin,
How did you come up with 4Kg/mm being 400lbs/in?

Using Scooter math, I get 224lbs/in.

1 lb = .4536 Kg
1 in = 25.4 mm

Just for reference, the 4Kg/mm front and 3Kg/mm rear is relatively close to numbers posted for the STi Ver 5 springs 4/3.3.

Um, I started typing too fast, that's how. The TEINs actually come with 7kg/mm front springs, which is 391.16lb/in.

I'm surprised no one else caught that sooner!
