These are Infiniti G35 gas pedals available from StrictlyZ parts..

they are $70 for automatic and $90 for manual.....

would they look good and possibly fit ok in my 280Z???

Not sure if they would fit, but, the definitely look great. Will they give you money back if they don't work? I'd love to know what you find out because these are really nice.

The left foot rest is huge and might not work on the stock small unit.

It might depend on how they install on the pedals, it might work with no trouble, and then it might take a little modifications to your existing pedals.

Some of the pedal sets I've seen only clamped over the top of the existing pedals, and then there are some that are made to bolt through the existing pedals with the mounting bolts made to look like they were part of the design of the pad.

I've got a set, that I can't remember where I got, that clamp over the stock pedals, but it doesn't fit over the throttle pedal as well as I'd like. The stock pedal is a bit longer than the pad and still shows a bit. I'm going to take a throttle pedal out of my parts car and cut it off and drill mounting holes and mount the pads with counter sunk bolts.

Best thing to do is ask if it will work before you shell out the bucks.

sorry to break it to you, but those are the aluminum pedal kits from the fx35/45 and the dead pedal from the 350z. it would have been pretty cool if my g35 came w/ that tho. you can find details of the install here. i remember there being something strange w/ the bushing, but if you go for it, good luck.
