For those of you out there who have switched from springs/struts to a full coilover set up, can you guys comment on any measurable improvements it has made on the track?

i.e., the spring/strut set up you had, the coilover you switched to, and the particular track you were at and the times with similar conditions?

I'm wondering if a very well set up spring/strut combo + sways, geometry fixes and whatever else can keep up with the same car prepped with just coilovers, and same driver.

I couldn't find a thread that contained this kind of information as opposed to a "which should I get, springs or coilovers" type of thread.

Cheers
