After over studying the spring choice, I committed to a set of H&R 52107 Sport Springs. Absent real data on the H&R springs, because H&R won't tell you their free length or spring rates, the decision was made for primarily three reasons:
1. Having installed them twice, I know they're well made and will yield 1' - 1.5 ", depending on sprung weight
2. I looked at the next best choice for my use, i.e. OME 2933 & 2941. These are close enough in free length to the 3" Nth Degree springs I have that when combined with the Savvy 1.25" BL, I'll end up with too much space between the tire and flare, with a 31" tire.
3. Price. A set of four was $238 delivered next day, from Tire Rack
Money saved when ordering the H&R springs allowed me to buy the following, for roughly the delta amount I would have spent on OME springs:
- New front and rear spring insulators
- New front and rear jounce bumpers
- New "Made in USA" CNC Machined 1" front and rear coil spring spacers
The later will be used to "tune" the ride height. If I only need two, the others will be donated to a lifelong friend. Once I get the ride height set, I'll measure and make my shock choice. This way I should be able to get the exact amount of up and down travel I'll want.
