Ok and I directly quote from custommaxima.com

"This kit provides matched spring rates and proper ride height to insure proper fit and function. Many weeks of research and development went into finding the maximum lowering without losing performance. Most companies are under the impression that lower is better.....not true. Tests have shown a decrease in cornering abilities and ride comfort on many spring kits that are to low for the matched struts. Our springs, lower your Maxima 1.5" in the front and 1.3" in the rear. This is the ideal height for the best performance. Custom Enterprise/Tokico Performance lowering springs are manufactured with chrome silicone spring alloy, heat treated, shot peened, block set, phosphate treated, and powder coated silver. Tokico stands by their products and are offering a lifetime warranty.

Factory Spring Rates: Front: 131 lb/in. and Rear: 194 lb/in.

Custom Enterprise Spring Rates are Front: 111 – 225 lb/in working rate and Rear: 148 – 295 lb/in.

I have b&g springs right now which are a 1.6" drop and my rear end sags. I'm tired of it and ready for something new. Reading custommaxima's info here my 1.6" drop is to much. Perhaps I'm confused I thought the lower the center of gravity the better a car will hold the turns...assuming it has the proper shocks as well. According to this though 1.5 front...1.3 rear is the best. Last time I checked most race cars barely drag above the ground. However I know that some autocross cars have coilovers so perhaps with coilovers its best to sit low due to spring rates..but with lowering springs its better to sit a little higher.

Someone please elighten me on the situation because I was considering going with sprints. I guess it could be custommaxima.com bs too..........lol
