I am looking into some performance parts for my Bonnie. Was wondering if there are any lowering kits, body kits, headlight kits, and such to change the look some. Can you please share what and where, also it's anything interchangeable with same year grand Prix?

Unfortunately, just about everything will have to be custom made for these cars. Nothing interchanges with Grand Prix as far as visual stuff.

Performance - Without a blower it'll take a cam and bolt ons to get over 200whp naturally aspirated. Search top swap and L67 swap. ZZP and Intense are the major vendors. Turbo setups will require a built trans.

Appearance - Nothing off the shelf is available.

Suspension - Click the link in my signature. 92-99 is all the same.

If You're serious about the performance side, you would want a built 4T65E-HD trans not the 4T60. you can extend the life of your trans by installing a shift kit and and aftermarket cooler that cools the trans fluid down after it goes through the radiator...or you could bypass the radiator's trans cooler completely, but that has other implications/issues in cold weather climate areas. You will also need or need access to tuning software such as HP Tuners, it will pay dividends in the long run vs paying repeatedly to have your pcm re-flashed by a vendor every time you decide to change up your setup with new parts, bigger injectors, added intercooler, different cam etc.

99s have the 4t65-e, which have been in the 12s on the stock, non-HD, diff with blower cars.

IIRC 97 was the last year for the 4t60-e behind the L36 and 96 was the last year for a 4t60-hd behind a L67.
