Okay, I'll likely get hazed for this but I'm willing to take it haha.


I drive a 2004 Pontiac Sunfire 4 door. Its a good car no problems with it in the 20,000km's that ive driven it (its at 100,000 now) Im pretty bored with my stock rims because they're small and ugly. I also dont like how loose my suspension is. It feels like im going to roll the car at 25km/h going around a corner. I want to replace the suspension and lower it an inch and a half (not to much but enough to make a noticeable change) When i do that i want to throw on some 17 or 18" rims.

My only concern right now is when i go over a bump the entire interior of my car rattles. I've started to fix some of it and its already better, but i can imagine with a firmer suspension the car will rattle a bit more, is that the right assumption?

One of the things that I notice rattle is my manual window arm's. I thought about putting a couple of "O" rings on each on to stop the vibration but I dont know if that would work. Is there a way i can make it not rattle? I'll be purchasing some dynamat for my rear deck, i do have a sub and while it doesnt rattle a lot it does rattle enough for me to hear it.

Is there anything I can do to prevent rattle with the new suspension?

There is not much you can do about the rattling. I have an '03 Cavalier and the dash vibrates and squeaks all day long. The J-bodies had major issues with NVH during their entire life span.

You might want to try stiffer dampers first, before replacing everything. Just my two cents, whch might save you a few cents.

On the other hand if you're lowering it anyway..

As an former avid J body owner and a member of Jbody.org for years. When you get lowering springs I perfer Eibach. You will need to invest in new shocks and struts like Koni Yellows. Your stock shocks and struts will go out within a year. Also if you want to reduce body roll, You don't have to go all out like I did. ( upper front and rear strut bars, Lower front and rear anti sway bars and a sub frame brace to boot) At first just buy the lower rear anti sway bar. If that isn't enough I would suggest getting an upper front strut. But to get the upper front to fit properly you will need to get an aftermarket intake. Then because of the intake you will start to run rich, Which will lead to clogging your Cat real quick. I would suggest getting atleast a highflo Cat, And possibly a high flo muffler with a Resignator please no Weedwacker exhaust.

Rims I had 17's, 18's, and one of the first on the jbody.org to put 19's on. To be honest with the J Bodies wheel well and when it is lowered. The most eye pleasing size is the 18" rims. Trust me when I say it is the most eye pleasing.
