The handling is a bit better than stock, and you can really tell the center of gravity is lower.The back is soft, but not so soft that theres no oversteer, almost perfect combination with the front. Its really smooth on the freeway and longer trips. I'm planning on putting in Koni Yellows so I can adjust the dampening and stiffen it up when I want, that will be the big difference. Definitely good daily driver springs and shocks.

I think you just made up my mind on the suspension. That looks like what the designer intended the stance to be.
Plus, it's still got some clearance for the front lip so you're not picking up every dime you run over.

Yeah thats what I said. I went over to my parents house this weekend and parked next to my moms e46 325 w/sport package, it looked like the same style of drop. This is how they should have come from the factory.

You'll find that there is generally one optimum damper setting for a given set of springs. Save your money for some track days or autocrosses! The other thing is to buy the best tyres you can afford.

I think they (KYB'S) would be a good alternative for someone with less than 200# fronts that did their own work. At a regular shop the labor costs would make Bilstein's the way to go. They're less than half the cost of HD's or sports.
Has anyone had both of these spring sets on their car? I was curious as to how much difference it made in under/over-steer characteristics.

Oh Im aware of that, I drove a car for 4 years with fully adjustable coilovers. Its nice to fine tune and be able to go soft when your going on a road trip. Track days and autocross I don't drive cause I'm on the side taking pictures for $$$. My suspension setups have always been tuned for the street, keep in mind that when I commute I usually take the canyon roads.

10 miles of twisty fast paced roads a twice a day is very healthy..

But when you go soft, the car is underdamped and that can be worse for comfort...

True, Im kinda veering away from the yellows and gonna stick with the KYB's for now. When time comes to change Ill probably throw in some Bilstein's. But my fronts are GR-2's and the rears are plane old Gas-A-Just, I dont think they like the new position and the dampening is really weak. Maybe some better rears are in order???

Sounds like it. The H&R's are quite stiff and need a good bit of damping.

when the ride os overdamped it makes the ide too harsh and keeps the suspension from reacting quick enough. When it is underdamped the car crashes over bumps and the weight transfer can happen too suddenly and give bad handling and ride too. When it is just right the ride is usually at its best.

I do like adjustability though as the car can be tuned for the surface/course you are on. Daily driving is a combination of compromises but adjustable shocks let you fine tune the weight transfer and suspension reactions to various surfaces. Autocross with one set up on an open flat course and then on a bumpy or tight course and your optimum damper set ups will be different.

I'll go adjustable every time...

If it is very overdamped it can even jack the car down!

Strictly speaking you'd want to match the springs (or even the roll bars) to the surface first, then the dampers. The softer the springs the more efficent the mechanical grip so they better they are suited for bumpy surfaces.

I don't think I would like to Autocross with softish springs and stiff dampers...

I have the 29664's, the rears are softer than the standard 91 318 is springs.

These springs aren't stiff what so ever.. are you thinking of the H&R race springs?

nomad · « **Reply #43 on:** March 30, 2007, 09:49:28 AM »

So where are you guys buying your springs and shocks?
I'm going to get the 29664s most likely.

sumyungguy · « **Reply #44 on:** March 30, 2007, 01:48:18 PM »

I got my springs from modbargains.com, After extensive searching they where the cheapest shipped.. $229 shipped
