I have the apex wheels with over 50 track days on them and they have held up really well. Keep in mind wheels are disposable, so you will need to replace them eventually so dont be shocked when they fail at the track eventually
I am sure the OEM wheels are fine since they are engineered for these cars and are obviously OEM. Forgeline is much higher quality and holds up better. Not sure about the specs...
IMO, you don't need any upgrades at all. Use that money on track time and having an instructor beside you. I guarantee you are no where near the limit of your car.
EDIT: Maybe widened wheels and tires with a square set up if you see yourself going more than twice a year. 305 all around.
I don't disagree with anything you wrote. I just don't think raising it makes much of a difference, downforce wise, compared to a real aero set up. The data would reveal this. Changing the end plates would have a much bigger impact. An amateur driver at an HPDE is not optimizing their aero set...
We are on a discussion forum. Anyone is free to comment on this thread. Don't be so close-minded when someone asks you a question. Especially if you are considering asking up to $2k for a wing mount set. I am not sure how anyone could vote given the non-existent data you provided. You have yet...
Aero is optimised for the chassis - it may be true that higher up the wing does receive free-er air, but if it's placed too high, it won't be making as much downforce. Downforce is created by the speed difference above and under the wing, if the wing is too high, the speed below may not be slow...
It is silly to pay up to $2k for wing mounts. The company I suggested can make the mounts in carbon for far less in the exact same GT4 style if you wanted.
Cheers,
Does he have the tooling? It looks like these are cheap 3d printed mounts. Are these mounts just some cheap copy or were they designed by an engineer who knows what they are doing? Do they have any sort of wind tunnel testing or any validation they actually do something or is it someone's guess...
