If you drive your car aggressively at all, go for the SRT option.

You'll save at least $150 and be able to put that towards a good set of camber bars. Then again, you said money is no object.

If you JUST do Eibachs, you'll get a bit of extra negative camber in the rear over the factory stance. Great for handling, bad for tire wear.

Personally, I'm an SRT spring fan. I trust the racers on this forum... and when they REMOVE Eibachs due to increased lap times and instability during hard cornering, that's a sign to me that not all "low" springs are created equally.

Compliant springs are never going to be the fastest ones, just as a soft mattress doens't give the support of a firm one.

And, you can't argue with the stance either

My setup is #2 pads up front, #1 rear, and SRT springs minus oone full coil, with TVT Camber bars in the rear. I'm getting the full laser alignment this week, so everything will be back to perfect factory spec, even at this ride height.
