Hi, need to lower car and have been looking at the blitz superflex lowering springs. I don't want the car to be decked and i do a reasonable amount of motorway driving so i don't want it to be silly hard, so these with Front minus 35-40mm and Rear minus 25-30mm claimed lowering seem just right. Just wondering if anybody else has these springs on their car and can tell me what they are like, how hard they are etc. Also can anybody recomend any other springs that lower around 30mm and dont make for a back breaking ride. Cheers
