• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Extremely comfortable seats

    I tried performing a search and found little. Anyone know a way to make the driver's side seat more comfortable? I'm talking long drive without walking like an old man comfortable. I'm thinking of taking it to an automotive interior shop and see what options they have that don't involve the...

    Clunking noise

    Just had my struts replaced (KYB's in front and rear) and had my car aligned. When I got my car back, it is making a clunking noise when moving the wheel more than 50% of full travel. Almost sounds like metal tubing/rod that is stuck and it vibrates. It only happens during turns. Any ideas?

    Wheel weight

    Looking at buying new wheels and found that lots of places have options to search by wheel weight. Out of curiosity, how much do the 16" wheels weigh on the 2008 Grand Prix base? Just curious.

    Not worth it

    One of the guys at ZZP told me it wasn't worth messing with a 2008 due to the PCM. I read people swap them out for older PCM's. Is it really that difficult to go backwards? Is it worth it? If there are any folks with 2008's, I'd like to hear from you.

    STS kit by Intense Racing

    I tried looking for a thread I once found on this forum and I can't find it anymore. There was someone who installed one of the "bolt" on kits from Intense Racing that was going to go public but never did. I'm wondering if that person is still active on here. If so, I have some questions for you. :D

    Number crunching

    There are some great write ups on here discussing various upgrades. Does anyone have numbers on certain upgrades? The reason I ask is because I'm investigating if my '08 Grand Prix with a 3.8L can achieve 300-350 HP at the crank without getting into the engine. Manifold is ok, rockers... I'm...

    Fluid exchange caused leak?

    I took my '08 to a oil change place and had them do a power steering fluid exchange. Ever since then, it has been having a slow leak. By the looks of it, it is coming from one of the lower components away from the block, around centerline. Anyone ever have problems with fluid exchanges? I tried...

    Intense racing

    Is Intense Racing still in business? Sent some emails to them with no response. I found a few threads on another forum that were dated a few years ago and an STS turbo kit that was supposedly in the works but no one knows where to buy it.

    Body packages

    I was looking at doing some upgrades to my 2008 GT and came across the Inferno package. First, it looks really cool. Second, it saves a bit of weight. Second has more benefit for me since I like pushing my car. They have the option between fiberglass or carbon fiber. Does the carbon fiber kit...

    W body noob

    Hey all. I've owned my 2008 Grand Prix GT for years now and honestly, I'm looking to make it handle better. I browsed around the forum and saw some stickies that answered some questions but a few remain. It seems the 2008 is a real oddball and what works for older models may not work on my car...
