Get the rim/tire you will be using first...Choose a quality tire with a lightweight wheel with the correct offset...Then figure your budget and based on that, choose your dampener and coil combo...Sleeve Coilovers use Linear Spring Springs which are very stiff but allow for adustment of ride Height...Springs come in Linear and Progressive and are what all factory cars use whether its the Hyundai Excel or the Enzo Ferrari...Real Coilovers are the most expensive but are properly matched for a more perfect combination...Company's like Tein that actually do research make their products for the specific chassis they are for...For example, the 92 Civic Hatchback has a Coilover for that weight and balance...The 95 Integra Hatchback has a Coilover for that Weight and Balance...The 95 Integra Coilover will fit on the 92 Civic Hatchback but it will have a higher dampenend strut and a stiffer spring, since the integra has a greater weight and is balanced differently...

You can use this fact to your advantage...

I personally like a Real Coilover but if money is a concern, I opt for a quality softer spring with a Highly Dampened Strut...

Something like the Eibach Sportline Series with a set of KYB AGXs and Skunk2 Upper Control Arms...
