I love having extra holes to lighten things, I built some great race car parts out of sheet metal and drilled big holes, used a dimple die to make them super strong, lighter and better than flat sheet metal. I have also drilled hundreds of holes in hoods, trunk lids, pillars, roof supports, etc on caged cars to reduce weight, very long time racer trick as weight is the all time enemy of all around performance so when I get free weight reduction in extra holes in wheels I am happy
I loved the look of the slotted holes on these Dial In wheels on my car with holes also in the rotor hats and hubs, seeing all the way through them looked really cool to me. I have a brand new set of these wheels I need to list up for sale, 15x9, 12.8lbs, second set I had, tires mounted then taken off, never mounted on a car, the Helix came out so I bought ten of them, better spoke design, stronger for racing, weigh a bit more, just round holes so not as cool looking.
No holes on the Helix but a stronger spoke and center design, still looks great.

If one must run a 17" wheel and drive on bad roads the 17.9 lb low cost 17x5, 4x108 bolt pattern XXR 527 seems a pretty good way to go as long as they hold up and they should do pretty well as a very solid design.

The OZ LM in that size but twice the price, low pressure cast so nothing special as for that money it should at least be flow formed and weigh less, seems way over priced so paying a lot for the name it appears more than the quality the price would indicate. For less that kind of money one can do the DIY 4x100 conversion and flow formed 17x8 wheels, Konig made Advanti Storm, 16.8 lbs, stronger and lighter wheels, $214 each.
For even less money there is also the Konig Hypergram, 16.3 lbs, 17x8, $165 each or the 17x7.5 Runlite, low pressure cast, 19lbs, $139 each and likely just as strong as the OZ.
OR, the best overall wheel size for this car, 16x8 Enkei RPF1, flow formed, 14.8 lbs, $214 each. Note, these will not quite fit over the standard 12.19" rotor WW BBK but there are two companies working on a different setup, one for sure will fit as I helped work that out for them to be available for my fellow enthusiasts as considerable cost in time and money as I just had to help make it happen, no profit for me except knowing others can get them when ready and they one set is specifically being designed to fit under some 15x8 and wider wheels
