I've read some sketchy things about the MP replacement springs, but whats the straight scoop? are they okay? I'm looking at a set of the HD springs, as my originals are a little sacked out.

This car only gets driven about 1500 miles a year, with a handful of days at the strip mixed in. It runs low 12's now, but should have high 11's in it. I'll eventually invest in a set of CalTrac bars as well. For now, I'm using a set of South Side Lift bars. The guy at Cal-Trac said the mono-leafs really don't start to pay off until the car is in the 10 second range, so I'm thinking they're not right for my car.

What's the best option for new springs?
