Remember that the lifetime warranty is only going to be covering defects in the materials, not the quality of the design or even a guarantee that you will be satisfied.  Since the sleeve and threaded perch don't really do anything, they can't really fail in a way that would be warrantable.  If the threads jam or cross thread, that is user error and won't be covered.  If the thing rattles (most do) or doesn't sit right, the warranty won't cover that either.  The only real potential defect that could be covered is that the springs shouldn't fatigue and sag too much.  That is better than some of the super cheap ones that you can expect to sag because of the poor spring quality, but still not saying much.
 
Still, the biggest issue and cause for failure or damage of a coil-over kit is how it is installed and used. Be careful and generally being conservative in lowering is smart. 
 
Before buying, ask what the inside diameter of the sleeve is and compare that to then outside diameter of the shocks.  The fit should be as close as possible or you will have movement, noise, etc.  Some kits use O-rings, shims, etc. to keep them centered which is better than leaving them sloppy and loose but it certainly isn't a replacement for a proper fit.  Also check to see how the bottom of the sleeve will sit on the spring perch or platform.  It needs to be solid and square or it will load imporperly, sit askew, etc.  These are the big issues of generic kits like this, even before you discuss spring rate and quality.
 
I hate top be a wet blanket about coil-over sleeve systems but generally almost all are poor and the risks of issues are great.  I've messed with a lot of them, made my own from proper KONI parts.  I no longer use them for street use and gone back to a good quality, fixed height performance spring with no regrets at all.  In the long run, I firmly believe that for the street that you are better off and will have less money in a properly installed set of standard performance lowering springs of good quality (Eibach, H&R, Neuspeed, Intrax, etc.).

betting I've owned more CRXs and CRX performance suspensions than anyone here

Yeah, i ve actually found  a set of springs for about 150 that have a lifetime warrenty.  Thats coilovers, not just springs.  I figure f its got a lifetime warrenty, why not.  Ill try them and see if they work.  Thanx for all the input.  Danny

I have mentioned then problems coil-overs before and will keep it quick (for me at least).  You get what you pay for and it is not necessarily just in the metal pieces that you buy, it is also the engineering and decisions behind the pieces.  Most of the companies selling threaded sleeves and cheap springs are simply copy-catting the good stuff like Ground Control.  If I wanted a sleeve system, I would go no where else but GC.  I know the people and beleive they know better than anyone else what is going on.
 
Being in the suspension business, I don't think I have ever seen a car part that has generally caused more damage to or screwed up more cars than cheap coil-over kits.  At best, they are not the right way to do it.  At worst, they will damage your car. Even when well designed with good parts and engineering, they are simply tools to can be used right or wrong (usually wrong) by the owners or installers. A hammer is a really great tool for driving a nail, it is really good at smashing your thumb too.
 
Most dealers know cheap kits are trash and don't really want to sell them but do because kids without enough money to do it right demand that they sell them.  The return and complaint rate is through the roof.  Caveat emptor (buyer beware). 
 
If someone truly sells a sleeve only really cheap and suggests that you cut your factory springs to fit-  OH MY GAWD, RUN FOR THE HILLS!

Hey, i need help finding some coilovers.  Ive got some KYB G2 shocks, and i want to put just some basic coilovers on them, and i want them cheap, but not to cheap.  Ive heard the real cheap ones tend to strip and lock up.  Whats the cheapest pair that will last. Thanx, danny.
