DGRacing said:Actually, it does. I'm talking to Ken Brown about his JRZ coilovers and as part of their service offering they will provide specific tunings for specific tracks. Some tracks are right turn, some left, some with more turns than others, etc. Tunable suspension is very important to winning races and are shown to do just that.
I will have my coilovers tuned per track. However, that's more for winning races than just personal lapping. So if lap times are important, and perhaps winning races with better times, having the proper rig is part-and-parcel to doing that. No question!
I thought that is what I said.
The question had to do with absolute lap times. In absolute terms, I claim there is negligable difference in a tuned coilover suspension and and identically tuned standard suspension. In most cases (and certainly for anyone asking this question), neither will be tuned for any track. Spring rates will be a best guess for the car and maybe driving style.
As I said, the advantage to a coilover is in it's flexibility to be adjusted to different tracks, something that typical track drivers can't be bothered with. Most coilover users that I have ever known have run a set-it-and-forget-it setup. Maybe it's better or maybe it's worse than a standard suspension upgrade. Neither is generally tested so...
I have never known a non-racer to change springs on coilover setup.
Anyway, sorry if I was unclear, but it looks to me like we are in complete agreement. Sorry if my post was confusing.
