Hey guys, my name is David and I own a '99 pontiac grand prix. Its my first car and we've been through quite a bit (though mostly repairs) but its a never ending work in progress and I thought i'd get a build thread going for it finally. I hope you enjoy reading!


Here's how it looked when I got it, ready for some offroading with that ride height haha



First on the list was a new head unit and and sound system. I had never even heard of a sub until I got a car, but the stock cd player was broken along with 3 of the 4 door speakers. I got Infinity kappas front and back and my uncle's friend got me a deal on a sub and amp. Now I can't imagine ever having a car without good sound.

I didn't like the messy box in trunk look with wires everywhere so i cleaned it up with this plywood pannel and carpeted it.



I got a cai and installed it, but i forgot to take pictures of it on my car. This stayed on for a while until...

My engine spun a bearing. To this very day, my mom swears it was the intake's fault.
So after some messing around and desperately trying to get the supercharged version from the junkyard, my parents insisted that a friend of a friend rebuild the internals because we would be able to get a warranty so I remained N/A. But I was very happy to have a practically new engine.
I was still looking for some cheap things to make it stand out a bit. Sooo... I got some fresh tires, and after a few weeks, a paint marker haha



I liked how it looked and I think it suits the car okay, and its definitely inexpensive haha. I decided to fill in the letters, but went to outlined letters.




Next up my for a birthday present from my parents, I got some tint installed. 15% all around



I see a lot of people rolling on mustang rims around here. They're absolutely everywhere on craigslist so I gave it a shot

I also did a debadge because grand prix gt are really long and silly looking badges





They fit pretty good compared to my stock wheels, but I wasn't happy with them and sold them.

I "fixed" my tail lights by drilling a few tiny drain holes at the bottom and tinted them to hide the ugly. I taped over the reflector to keep it classy and avoid the murdered out look.

I just rolled around on my stock wheels like this for a while craving to go low

Now the fun starts haha. I had been saving up for some kind of suspension and I really didn't like the idea of anything except coils, i didn't see the point in anything else. It was a really slow process saving up, but one night on the way home from a hurricanes game I got rear-ended and the insurance money put me right at what i needed for some coils

damage on my bumper. her car was pretty messed up, but the pontiac is a tank



I got the HT motorsports coils. The guy was real helpful and his service is great, well worth the extra money versus trying to make some. They have KYB AGX inserts with 4 levels of dampening and #400 front springs and #300 rear springs.

My purchase




Installed the fronts



and the backs



And here's how it currently sits. The stock suspension was like riding on sticks of butter, this is so much better and rides great. I occasionally hit the bump stops but theres some room for the adjusters to wind down more




Im still rolling on stock wheels super sunk in, but not for long

My newest purchase
