any one had any experience with eibach springs for a stiffer ride and lower profile. would like to improve my road stance and cornering and would like to know if i will get significant improvement with a change in springs. thanks in advance as i always get great info here.

 

I had them. They ride fine and improve handling. The reason why I have changed to the M030 was because when I put aerokit it was low for my driveway. I would have to go in at a extreme angle and that was getting old. The kit was suppose to lower it by 1 inch and handling was improved significantly, however H&R was suppose to lower 1.25" and my friends look the same as the eibach. Compared to the M030 it was about the same in terms of handling although I have not DE the system yet. Most people would suggest to change the shock, but your car is a 2002 with stiffer shocks. I would try them with out the aftermarket shocks to see if you like it. I used stock shocks and they worked fine on the street, but on the track is a different story. Remember my car was a 2001.

 

I will most likely not be tracking the car just want to improve handling. planning on a GT3 for the track.

 

Try them they are only $325 at tire rack.

 

Try and get a ride in a car with the springs/standard shocks set up you are considering before deciding this the best route for you. For the best ride, handling and safety the shocks should be matched to the spring rates. I am not familiar enough with the spring rates and/or the rates of the standard 2002 shocks to say that this combo is not a good match. However, I am sure someone like Viken could shed some light on this.

Poorly matched springs and shocks, while they may look good, and while the set up may reduce body lean in corners as a result of the lowering, this set up will not necessarily improve overall handling. Without properly matched spring and rebound rates either the shock or the spring will over power the other resulting in a poor riding car and/or mishandling car (the mismatched rates usually manifest itself with a "choppy" ride over road undulations).

Also consider the cost. Whereas new springs alone may be inexpensive initially, if you do not like the ride this method will cost more in the long run than just getting the proper set up the first time because of the labor cost to associated with installing the set twice (unless you do it yourself).

 

My H&R sway bars eliminated almost all my body roll,they made a better improvement than my spring and shock modifications and they were $600.

 

The whole shock spring match is a selling point. I agree you will get better handling with shocks and spring, however if you read the PCA article comparing US stock ,M030, and ROWm030 you will realize that the us m030 has the same spring rate as the ROW. Howevere the front shocks on the sport US car was softer than even the stock suspension, but the rear was the same compression, but stiffer rebound. Given that the spring rates of the H&R are a little more stiffer than the M030 in the front and the rear are about equal. If you put them on a stock shock you will probably get equal rates compared to a US sport suspension. Its not perfect, but I don't think it will be dangerous as some say. if you read the H&R site they also claim their spring work fine with stock shock, but it is not optimized for handling. It all depends how much handling and perfection your looking for. Any way how can you explain how the PSS9 different shock setting be optimized for one set of springs with 9 different shock settings, It all depend the type of comfort and driving your doing. the only real negative i can see with stock shocks is that they might not last long from lowering since they might bottom out more due to a low height.
