the shop should know what is compatable with your car... not all suspension parts are swappable between models
you can put monroes on the front only... but it is always better to have all 4
this is because the dealership is also called the STEALership
i have 14" steel and they are freakingly heavy... alloy wheels are lighter and 14" to 15" upgrade is not going to put too much strain on the suspension
got no recommendation for wheels... sorry
i never said i don't like to talk in english... in fact i DO love to talk in english bti always try to answer in the form that best suits the post owner
