Choosing +30 directly does seem more straightforward. The lighter and cost-friendly 17" wheels are a tempting option. Might be worth leaning that way for track efficiency.Choosing a +30 wheel makes sense., it uses less hardware and simpler.
About 17" or 18" for track use, both can be great for track. however, 17" are lighter and can be cheaper so most drivers prefer this.
I'm sizing up track wheels for the GR86, considering 17x9 or 18x9 setups. If +45 with a 15mm spacer works as +30, would it make sense to choose +30 directly? Wondering how 17-inch wheels compare to 18s for track use.
17x9 +30 wheels are an excellent option for track use,they're lighter, more affordable, and more efficient. You'll save weight, plus the tires are easier to come by. If you're working with a spacer that has a +45 offset, going with +30 is a simpler choice. While 18x9 might provide better grip, 17x9 is probably the way to go for efficiencyChoosing +30 directly does seem more straightforward.

If at all possible, use a native +30 because it is cleaner, requires less hardware, and eliminates spacer stress. In terms of size, 17x9 tires are lighter, less expensive, and have better compliance, 18x9 tires clear large brakes and offer more tire options, but they are heavier and more aggressive. Unless you're chasing particular tire sizes or using large brakes, 17s make a lot of sense for the majortiy of GR86 track setupsI'm sizing up track wheels for the GR86, considering 17x9 or 18x9 setups.
