Have read many posts about lowering springs and think I have it narrowed down to BTG or Eibach, but have several questions / concerns:
1. Will ride quality suffer too much for daily commuter with either set?
2. Am I in constant danger of scraping the front end?
3. Have read posts of scraping or rubbing (bottoming out?) rear tires with 4 adults in car?
4. Occasionally have need to haul 160-200 lbs of bagged salt...will this present any problems?
5. Last... BTG pricing is very aggressive/tempting ($140), so are Eibachs that much better?

Any and all input / experiences appreciated. Thanks
