What is SPC?
SPC stands for Special Product Company and they make an array of alignment parts including adjustable control arms, camber bushings, camber bolts, adjustable strut mounts, and specialty tools and equipment. They have been in business since 1972 and make a variety of parts for European, Domestic, and Import vehicles. They particularly specialize on high performance/enthusiast cars. Some examples of vehicles they make products for include E36/E46 BMW's, G35's/350z's, and Mini Coopers.
Features and benefits:
A lot of these parts are not specifically for modified cars and can be used for stock vehicles. While these parts are more useful on cars that have been lowered they will still offer major advantages over stock components when it comes time for a wheel alignment. For example, Volvo C30's, S40's C70's etc have an issues with the rear lower control arm and tire wear. Volvo redesigned this control arm to address the tire wear issue. SPC makes a complete forged adjustable rear control arm that is not only cheaper than the stock part, but is more durable and offers better alignment adjustability.

In addition to added adjustability these parts are also much more durable. For example the strut mount kits should last the lifetime of the vehicle since they are made from billet aluminum.
If you are considering lowering springs or coilover kits please see what SPC has to offer for your vehicle. Lowering a car can have a negative impact on performance on occasion if alignment specs can't be dialed in, also tire wear can be increased due to poor alignments from limited factory adjustability. These parts will meet both performance and stock replacement needs. At the end of the day both performance enthusiasts and non enthusiasts understand the importance of proper wheel alignment. These SPC components will help them drastically.
Other things to mention:
I also want to explain a little more about the front strut mounts. These are made from billet aluminum. Unlike factory rubber strut mounts which reduce vibration and noise these will tend to be a little louder. They can be noisier over bumps but that is also contributed to having a small tire sidewall as well. Most performance enthusiasts will know this but it is important to mention this to regardless. However, it will not affect ride comfort.
