Here is a link to the sizing options. https://www.barracuda-europe.de/en/b...ck-polished-2/

I currently have stock 2003 350z rims. I'm running the FIREHAWK INDY 500 tires. Will any of the Barracuda Tzunamee wheel options work without modifications to a stock z? If not, what modifications would be required?

 

Three, er, wait, four points (3 objective, 1 absolutely IMO, so you can disregard but I'ma gonna say it anyways.

First the objective...

Point 1: WEAK specs. Assuming 18s you're interested in. 18x8 is the size of a stock FRONT Z wheel. Putting those on the rear equals downgrade (other than comparing to the early wagon wheel Touring wheels which are 18x8 square.

Point 2: No offset specs listed. I'd be wary of a wheel mfgr who doesn't list an even more important spec than even width.

Point 3: They are heavier than the wider (8.5") stock wheels. At 26#, that's a boat anchor and hurts performance due the width and weight. Narrow and heavy respectively.

And finally, the subjective....

Fugly. 🤣

My take, save your money and even if you have to buy replicas or unique wheels like this set, at least get the right spec. Not sure what tire sizes you run but if you are using stock 225/45 and 245/45-18s, go with 18x8.5 front, 18x9.5 rear with offsets around +20 to +22 F&R.
