If you are lowering your car and are worried about this get a FULL COILOVER system. But if you lower your stock vehicle with factory struts YOU WILL BLOW THEM. Look at it like this, the factory struts on most cars run between $80-$110. Thats close to $400 to replace them. A decent coilover system can be bought for $600. Now you factor in the cost of the springs/ coilover sleeves you are looking at and its almost the same price. BUT you only have to buy them once. A full coilover system will not only allow you to change your ride height at will, but the struts that come with them will give you a better than stock ride, which means NO BOUNCING! the full coilover is also the easiest to install as all you have to do is pull out your COMPLETE factory strut/spring and replace with the new unit. If you need any help finding these let me know the year and make of your car and I will find the best/cheapest setup. My email is hondab16tuner@yahoo.com
