You will need spacers , atleast 35mm because the oem equipment is 16x7 so you have to include that extra inch.
I got those spacers from eBay for my 15" wheels,very cheap
No you need coil spring spacers or to replace them with heavy duty springs from a truck you will also needhub spacers so it will not rub
Not mickey thompson 15x8. Need spacers.

Original is 16 inch with 225/60 r 16. They went to 16 inch from 15 inch due to the size of the front caliper. But, you can still fit 15 in. wheels with 215/70 r -15 You need an adapter, 1.25 inch will do, and you will have to grind about 1/32 of an inch off the top of the caliper body. This will not affect the caliper. Check out (rigged.up ) or ford wheel spacers. Rear calipers are standard size.
2 inch
what size of car battery do i need for a 2003 buick lesabre
No, that's all the bigger you will want to go with out at least putting some body spacers or a suspension lift on it.
If you can not remove fasteners on outside, you may need to cut a section out of the inside of trunk to get your hand by the bulbs.
Yes, but you will need spacers to make them fit, this may however cause your wheels to hang out of the arch and in some states or countries this is illegal, so you may need to purchase arch kits too.
the LeSabre has a timing CHAIN. It does not need to be replaced. (unless you broke it :)
