ide like to get opinions from any of u guys that have had this before and what has worked for u? is it worth paying that $400-800, or can i find something with just as good of quality that will last, and not mess things up for cheaper?
thanks, any help appreciated
First off, welcome to the board. :cheers:
Suspension tuning is something that cannot be done half-assed.
The springs and shocks must be tuned to work with one another.
The stiffness of a spring must take the weight of the car into account as well as it's suspension design and chassis clearances. Furthermore, that springs "rate" (the rate at which the spring compresses - usually measured in lbs/inch or kg/mm) must be matched to the correct shock damping rate.
If a low-rate, softer spring is paired with a stiff damper, the damper will wear out rapidly. You'll have a jarring ride at first, followed by utter mush.
Conversely, if a high-rate, stiffer spring is used with a softer damper, the ride will be choppy at best as the damper is unable to dampen the cyclical compression-rebound cycle of the spring.
This fundamental concept is why 99% of the eBay "no-name" bargain springs are total and utter crap.
They are not designed with a specific damper in mind and are usually made from substandard steel. Unless you luck out and find a damper that works with these "no-name" springs, you're pissing your money away, IMHO.
The eBay coilover "sleeves" are even worse. The spring perches often corrode and jam, leaving you with reduced suspension travel and blown dampers.
In short, you get what you pay for if you try to do this cheaply.

Now that I'm done with the cautionary tale of suspension woes, let me offer a few bargain solutions.
1) KYB GR2 dampers, H&R SportLine Springs:
The dampers are non-adjustable, but they are designed with shorter pistons to allow for about 1.5" of lowering. The H&R SportLine Springs are about 20% stiffer than OEM, so they'll make a difference, without being overly harsh.
Budget: $500 - 650
2) Ground Control Coilover Sleeves, KONI Yellow Dampers.
In this setup, the dampers are adjustable (compression and rebound simulataneously), as is the ride height. Ground Control is one of the firms that is very concious about matching their springs to a specific model of damper, taking the guess-work out of the equation. The additional benefit of the coilover sleeves is the ability to "corner-weight" the car.
[It's a process of equalizing the weight transfer rate between the corners of the car, but that's for another time. If you're not planning to auto-cross the car, it's probably overkill.]
Budget: $700-800
3) Threaded body, adjustable coilover dampers- E.g; TEIN Super Street
These pair the versatility of the #2 setup with a greater range of tuning adjustablity. The SS damper still adjusts rebound and compression rates together, but the degree of adjustability is more precise. TEIN also markets the EDFC, a computer controlled set of stepper motors that allow in-car adjustment of the damping rates on the move. Also, the majority of these dampers are capable of being fully overhauled by the manfuacturer.
Budget: $900-up

I know I've ignored the camber & caster adjustment issue.

I'll get to it in a bit.
Yes, I'll be brief. :chuckles:
