The Pontiac Grand Prix GXP has staggered wheels.
The fronts are 255/45r18, rears are 225/50r18

That’s odd I wonder why? Why would you have smaller tires on the front of a FWD car. Granted it’s only sidewall height not width. Any ideas?

The wider wheels are in the front, the first time I’ve heard of this.

I remember this, it was a desperate attempt to balance the handling after stuffing a transverse v8 up front. If i remember the reviews it actually kinda worked.

Wider wheels on the front are probably since it’s FWD V8 with 300 horsepower. As well, sidewall height is represented as a percentage of tire width, so they’re actually not too far off (115 mm for the fronts, 113 mm for the rears).

Sidewall “size” is actually a percentage of the width. So a wider tire with a “smaller” rated sidewall actually could have the same sidewall hieght as a narrower tire with a “larger” sidewalk rating.
I checked a tire size calculator and in this instance the front tires are only .2 inches taller overall. And .6 inches larger in circumference. If the tires had the same sidewall rating the difference in overall size would be larger,

Wow - I’m ... staggered!
Thanks folks - two shows tomorrow night, and don’t forget to tip your waitrons!

There’s all sorts of fun facts on these - they also used a remote water pump to reduce the overall length of the motor and get it to fit transversely in there.

They stuffed an SBC sideways into an FWD car. Nothing in there is easy to replace:

Not as bad as the guys who stuff them in Fieros, making them more impossible to work on.

Just make the tires bigger. Also a huge reason why modern cars weighing twice as much as old cars handle so much better. Tires are everything.

Fair enough. But at least in a Fiero you already expect to have it up on a lift to do simple things. Interestingly enough, these LS4's also seem to find a home longitudinally mounted in things like RX-7's where the full-length small blocks are just a little too tight.

The rear doors open 112!degrees for ease of operation
It’s the only car (GTP)to get the L26 3800 Series III supercharged engine
Parts of it were used for the Solstice (along with parts form the GMC Envoy)
It was the fastest domestic V6 on the market
It had a built in G-meter
The aluminum V8 weighed less than the V6
The wheels and tires were staggered to compensate for the 64/36 weight distribution

Out of the four LS4 cars, the Pontiac was the only one to have this suspension setup. As such, it’s the only one you’d realistically want to buy; the handling of the Impala and Monte Carlo SS with this engine can be iffy, and that’s being incredibly generous. The Buick with the engine had it detuned.

I think the main reason you don’t see many of these around anymore is that aluminum block - the LS4 was basically an aluminum block version of the ubiquitous 5.3 Vortec. So it’s pretty sought-after as a V8 swap engine for all sorts of things due to the lightweight block and everything else shared with the Vortec being cheap to replace.
