Choice of Coilovers?

[AZFA20]

For what it is worth there are a couple of us out here in AZ including myself who have been running the full GroundControl coilover sets with various spring rates and various shocks with great results. I am not sure why anyone is claiming them to be harsh as I read in an earlier post. Mine and the others I have been in with the setup have been hardly different from stock imo with regard to ride quality. There are several suspension options that are good choices but the GCs are pretty awesome in regard to being able to set them up easily for different uses and styles of daily driving/road coursing/drifting. In all 3 categories they still manage to impress me. Depending on what you plan to use the car for you can get whatever spring rates you want. There are much more expensive setups but for the money the higher end GCs are worth considering.

I want to drop it about 2 inches but I read that dropping it too much will affect CoG and other suspension variables.

I'm looking at Ground Control. Only thing I heard was the ride was too bouncy. I like a firm ride.

Also cross shopping STANCE and Fortune Auto 500 since they're all not too far in price (about ~$100 difference in each)

I've read plenty of reviews of each coilover and narrowed it down to those three but I'm still undecided.

What would you guys suggest?

Dropping the CG is the best thing you can do for the vehicle's handling. What I think you're implying is the KRC or kinematic roll center. You can adjust the roll center height with various bits and bobs, but it isn't really necessary. What you really want to correct are the steer and camber curves (which coincidentally happens to be the same method) to maximize contact patch. The kinematic roll center is just a point in space, a byproduct of the geometry, don't focus on correcting that, focus on the curves.

And exactly how would you focus on doing so?

Short blanket answer: creating a suspension model to know how it articulates.

Expensive answer: K&C rig testing

Cheap and realistic way: driving. pay close attention to bump steer and grip, how much it changes, noting things like camber wear, using a tire pyrometer to record tire temps. If you have adjustable suspension bits, adjust according to those read outs and what you "feel." Not highly scientific or accurate, but it will get most people in the range of where they want to be.

Or pay someone like Robispec for their designs, built from experience, that are proven to work.
