If you want coilovers, you need Groundcontrols at a minimum. Don't be tempted by the cheap POS coilovers on eBay.
GC run about $300-400 depending on what type of deal you can find. Keep in mind, the GCs are only a sleave so you will need to upgrade your shocks at the same time. Using the stock shocks will create a horrible ride and will handle like shit. Personally, as far as shocks KYB AGX are the best period. The best price I have found is
www.p-s-t.com for $375 shipped (although prices may have gone up).
When you look at your suspension, wrapped around the shock is a dust boot (it looks like an accordion) connected to a hard piece of rubber. This is the bumpstop, it serves as a cushion so your shock dosen't smash into the chasis on a hard corner or bump. B14 are cursed w/ short suspension travel, meaning there isn't a lot of space the shock can travel before it smashes into the chasis. This is why the bumpstops are important (you can keep the stock ones but you need to cut them to make them shorter) along w/ the motivational mounts.
When your shocks are smashing into the chasis, your are bottoming out, damaging the shock, and possibly about ready to make your car spin in circles. Keep in mind when this happens, you will often never hear anything (it's not like scraping the bottom of your car), people w/ jacked-up setups often 'claim' they never bottom out when in fact they are because they don't know any better. This is why people who actually know a thing or two about suspension say never lower more than 2". There is a huge write-up on this topic on the mother of all b14 suspension threads. Check it out on the sticky, it will enlighten you and show you how much most people don't know shit about suspension.
One more thing, the uneven look is mostly w/ the Eibach springs. The H&R springs look much better but there still is a little difference in the level of the car.
