I need to know the difference between coilover springs and just regular lowering springs because I want to drop this Ac because it is severely in need of some cosmetics what is the difference between coilovers and regular lowering springs? Does my car need both or just one? Which is better?
coil over has the shocks inside the springs.it comes with both shocks and springs.regular springs come only with springsget the coil over.thats all you need
Rotating the tyres helps create even wear throughout the tyres. as you said yourself If you did not rotate tires the back tires would last through two sets of new tires on the front who wants to buy that many tyres? if you rotate them all 4 tyres will last quite a lot longer (depending on your driving style of course) and technically it's safer. So while the back tyres may last longer without rotation, they will still wear in specific places, if you know much about suspension like camber settings etc, you'll know that your car may sit to the inside of each tyre (slightly) those spots will wear and become useless for grip, thus rotating the tyres to give you even wear ALL OVER the tyre, not half use on one side of it till there's little tread left then throw a half used tyre. Might as well use every inch of grip possible before buying new ones :D
There are 2 schools of thoughts on this. 1) save yourself the work, because the tires that wear out first will simply wear out when they do you replace them as they do. I subscribe to the second school of though, because I am of the firm belief that it increases tire life. 2) Rotate 'em every 5 or 6 thousand. Rotate them in this direction: fronts go straight back (meaning L front to L rear same on R side) rears criss cross to front (meaning R rear to L front vice versa). School of thought #2 insures that all tires see each hub after 4 rotations. The wear will be equal, when you change 'em, you change 'em all at once. Obviously, if you are running big fat slicks on back, you can't rotate them in manner #2. Good luck.
coilovers are adjustable without switching springs. while lowering springs are set to lower to only a certain amount
Actually the first guy is part way correct. There are 2 types of coilovers. 1. the FULL coilover which is by far superior than any other option out there. You can take out the whole factory strut/spring assembly and just replace the whole unit. while it is the most costly it will give you just as good if not better ride quality than your factory suspension (no bouncing). This unit is also height adjustable to your liking without compressing the strut so if your car is 8 off the ground or 1 off the ground the ride will be the same 2. the sleeve kit. these are simply sleeves you put over your factory struts and can raise up and down using wrenches. while it is more cost effective, if you lower your car more than 1 your struts will pay the price in a few weeks. it compresses it beyond it's dampning capabilities and will eventually bust. Not to mention that when you are driving it will feel like you are in a horse and buggy from all the bouncing. Now onto the springs. The lowering spring is the cheapest way to go, again unless you replace the factory struts with lowering struts you will be buying struts in a few weeks due to compressing the strut to its limits. The ride is just as bad with MOST springs as the coilover sleeves due to the compression thing again. Now lets look at prices. A full coilover set will run anywhere from $500-$1,400 depending on brand. A sleeve kit will be anywhere from $50-$100 plus you will be buying struts every few months($90 each) Springs from $30-$100 again with the buying new struts every few months. then the lowered struts are around $300. The BEST is a full coilover suspension for ease of install, take the whole factory unit out and replace with new. and ride comfort, you wouldnt be able to tell you are cruising 1 above the ground.
