As far as springs I say you can go with Crutioals Im not sure how its spelled lol. but they go for around 250ish I believe you can contact M4 and im sure they will give you a good deal on them.
since your not a DD then im not sure why your plan on putting these rims on the car ? LOL, but usually people that put these rims on are looking for looks LOL these are definitely not for Track, Road Race, drag race or ... these are only and only for looks
. Unless you get the real Advans which is gonna coast so much but they are supper light
IMO I Highly recomment you to get the car lowered first then as far as rims just go to diff sites and look at evos with diff rims and diff tires sizes and then shop around for a proper size. cuz remember the Rim is one of the most impotant thing about your car and they can either make your car look Supper sick or They can make make your car look ugly.
Just take your time and with out any rush find the set that your looking for. Trust me I lost a lot of money by not doing enough of research and just jumping into things
.
let us know how it goes, and what your about to do maybe we can help you even more
. Good luck to you.
