I too am in the market for springs, but I'm more interested in handling (road course type stuff), but none of the manufacturers list spring rates. I also want a "level" drop.

I'm considering the FRPP K springs, but would like some comparison between others and spring rates.

Take apart a ball point pen, one of the click types.. There is a spring in there. Usually linear. If you pull it so as to stretch the coils on say half of it, then compress it you'll find the close coils the ones that were as original, will all compress before the ones with the bigger coil spacing. You just made a progressive spring.

The number of coils in a given space changes rate even if you don't change wire diameter, or coil diameter of a spring. Why? Well I'll let an engineer attempt to explain that...

To make matters worse, there are progressive springs that gain rate all the way through their travel, and progressive springs that are more appropriately called dual-rate where there is one rate, that transitions right to another. Most "progressive" automotive spring are that way, some are not. And there are times a spring like that is required since the stiffer and shorter a spring becomes if you don't have what amounts to a built in tender spring, it'd come loose at droop.

I prefer linear springs. I had variable rate springs on another car and it felt like a pogo stick on rough roads. The potholes would get the spring to compress into the higher rate portion and the shock wasn't able to handle the rebound. From what I've read on the topic it's hard to tune the dampening when the rate changes with compression.

I'm biased, but I think the steeda line of springs are just right in terms of drop & spring rate. I would not run the comp. springs on my roads though, the sports are plenty. The ride is rough but tolerable.

Well if you want a level drop, then forget eibach/frpp springs. You get rake like a mofo. Look into steeda for a level drop. It was just mentioned the front doesn't drop on a certain variety.

That is the one thing that drove me nuts with my last setup. Mostly on the expressway, though.

I used to run the Steeda Ultralite springs on my 05 GT. Handled very well, especially when I would run the Dragon.

By the looks of his sig pic, I'd say eibach prokit.

IMO those would be fine for the first few events because unless youve done some events before the driver will be the one needing some work the first few events not the car after about 2 maybe 3 events id look at differnt springs or tires, I would get brakes before i got different springs though the stock brakes on our cars suck if he already has the eibach pro kit.
