I guess the title says it all.
Is there a stiffer spring little to no lowering. Or is the coilover is the only way to go about it?

 

full adjustable coils is the only way to go

 

I think coilovers are the only way since you can set the ride height. You could try calling swift or another spring maker to see if they have a replacement spring but I have never heard of one.

 

^^^ it would ride like a bad camel

 

Coilover

 

Eibach pro kit lowers the car 3/4" to 1" I don't think your going to do much better off the shelf. If you remove the oem springs from the shock and do the measuring work, its possible there is a spring manufacturer such as Swift that may have a higher spring rate with the right length to reach your goal. But keep in mind it will have to be a shorter spring if the spring rate will be higher, otherwise it will jack up the height more then stock.

 

CR Springs......

 

Here are the OEM spring rates:

00-01 Front: 218 lb/in - Rear: 291 lb/in
02-03 Front: 240 lb/in - Rear: 230 lb/in*
04-07 Front: 256 lb/in - Rear: 207 lb/in*

08 CR Front 375 lb in - Rear 264 lb/in*
*values based on % change data, as lb/in specifications not provided by Honda

 

CR springs/shocks are what you want
