The Ground Control coilover packages
listed below range from street performance to dedicated track.
Ground Control coilovers offer huge bang for the buck and will give
a new personality to your car. Coilover kits are based on KONI
rebound-adjustable dampers known for there performance and
durability. The dampers used in these kits are the short versions
specs specifically to operate at a low static ride height. Ground
Control offers custom damper valving for stiff track-dedicated
springs. Double-adjustable (separate rebound and compression) KONI
dampers are also available for further tuning and
KONI dampers come pre-adjusted to
match the supplied spring rates using a shock dyno. Front struts
are are externally adjustable from underneath the hood, even with
the factory strut brace. KONI adjustable rear shocks are offered in
two versions. The standard version, which needs tools and a jack to
adjust, and the "top-adjust" version, which adjusts from inside the
trunk with no tools needed. The "top-adjust" option adds $100 to
the kit price (All kits except come standard with this option
except the Basic which is only available in standard adjust).
Optional double-adjustable dampers (Stage 3) have their compression
adjustment knobs located at the bottom of the damper.
Ground Control offers Complete
Shortened Front Strut Housing Machined from seamless DOM 1026 steel
alloy tubing with heavy-duty swaybar brackets welded on. This
design is much stronger and more rigid than any of the aftermarket
housings (most are actually modified stock housings), and these
units feature skip-welded gussets and retain all original brake
line and ABS tabs. The adjustable spring perches use an Allen head
bolt to clamp the single threaded perch into the correct position -
no secondary pieces are needed to jam the threaded perch into

Best coils. Best deal.
From Ben4 of Pittsburgh, Pennsylvania on 5/14/2012.
Upgraded from a cheaper set of coils (although still quality German components). I wanted something more aggressive for moderate track use and spirited driving. All I can say is this is the best move I've made on my e46 M3 so far! The folks at Bimmerworld do an awesome job if you have questions about spring rates and options so just ask! I did a lot of research and it seems those who know what's what run GC coils. Easiest to install by the way, there's even a good youtube video series installing these exact coils if you're a first time DIY. HIGHLY RECOMMENDED!
