Our kit incorporates a top spacer and preload combination into one piece. What that does is physically increase the overall mounting length of the strut assembly, effectively increase the amount the suspension can droop. When we made the kit we designed around the acceptable working limits of the factory suspension setup. Adding more top spacer will exceed these limits that we felt were the max working range. Things such as ball joints, CVs and knuckle clearance to the coil spring/strut assembly are carefully considered. I am not saying adding the spacer won't work...it will just exceed what we feel is an acceptable working range for the suspension.
Adding a spacer to a 100% preload style kit like Suspensionmaxx or the other guys is a little different because that style kit doesn't add length to the strut (top spacer) while ours already does. Ideally you don't want to be using your suspension at it's limits. We set ours up to still have plenty of functional suspension travel (compression and extension). Some other kits don't take all factors into account...yes they may give you 3" of lift or more but that isn't necessarily a good thing. Most of these tall kits are either excessively preloaded...bad on struts or excessively top spacer...bad on ball joints, CVs, tie rod ends, etc.
There is a lot of mis-information out there when it comes to the very popular "strut spacer" kits that are available for just about every vehicle made today. The real problem is that very good suspension companies have jumped into the market out of necessity and have made sub-standard product because it sells. This is compounded by a ton of small start-up "mom and pop" shops making product and selling it at crazy low prices on ebay, etc...I am not picking on just one person here, there are a lot of them. Making a product that gives lift is one thing (that is the easy part)...making one that lifts and properly functions is a whole different game and few people do it right. There are alot of performance, safety and reliability issues with many of the kits out there (speaking in general for several models). Price and ease of installation have become the driving force in kit design and quality, function and reliability have taken a back seat. We do things a little different around here.
I'll leave it at that. I could go on all day about this and probably confuse more people then it is worth. If you have specific questions I will do my best to answer them.
BTW...Thanks for buying BDS. We very much appreciate it.
