i have a question, im looking to lower my car somewhere in the 1" to 1.5" range and i saw these springs http://store.summitracing.com/partde...p;autoview=skuon summits site and am wondering if these will be to my liking. i see that they are progressive rate springs, is that good? and i also saw these u/l control arms and wondering if these are any good. ive heard that the granatelli ones arent any good and these look pretty similar to those.

thanks for the help
