Track day setup questions (17s 18s widebody etc.)
Of course there are many variables to consider as each track is different but I want to find out the general thoughts of the experts for the following questions.
The setup will be for Istanbul Park which is a long and high speed track since it was designed for F1 racing. A stock 458 Italia laps it in 2:16 and a modified EVO IX laps it around 2:20.
Which tire and wheel combo is better such track and for semi-slick tires? Square or staggered? 17s or 18s?
I already have Enkei RPF1s in 18x9.5 and 18x10 for street but I want to buy a separate set for track days only. I also have Pettit TrakPro Stage 2 coilovers.
Are wide fenders a must when getting serious (but not WTAC serious)? Most of the rotary performance shop cars have them but I'm not sure if this is part of the attention and promotion process or really needed? I mean with the right offset rolled fenders can accommodate 285s easily and even 295s or 305s if I'm not mistaken.
I would like to keep it stock body for now but I am open minded if wider fenders/wheels will make a significant improvement. No point in building a setup now and needing to change it again shortly after.

I would recommend a square setup. If you find rims similar to the size of your rpf1's, 265/35/18 will work. 275/35/18 will fit on the 10's also but may require the fenders to be rolled. You wont need wide fenders. If your a beginner , good street tires are perfect. Hankook rs3, dunlop z2, bfgoodrich rivals, etc. Then build up from there.
Your coilovers are good as a starting point. If they are adjustable get them corner balanced. With a square setup you should adjust the balance of the car with the suspension and alignment. If you want to get more serious, aero should be the next thing you look into. Obviously I am assuming that brakes, bushing, etc are all on point.

What kind of power is your car producing? What do you have for brakes? Once you put sticky tires on the car, you'll be going faster which means your brakes will be working harder. In most cases, this is the first area that begins to show signs of failure on street cars taken to the track.
As far as 17's or 18's, it depends on how much you want to spend on tires. 18's typically will cost more and you'll have less sidewall. I would recommend a 17 and run the tire a little skinny on the rim. Something like a 17x9.5 with a 245 size tire. If you run a square setup, it will produce more oversteeer. For me, I like oversteer more than understeer. However, understeer is safer for new track drivers.
As for tires, I don't know what's available in your area, but here are some that are getting good feedback from track drivers:
Hankook RS3
Nitto NT01
Maxxis RC-1
Toyo R888
BF Goodrich g-Force Rival

Planning to run stock bushings for now. I will probably get thicker swaybars. Brake mod is up next.

I have stock brakes atm but I didn't mention it in the original post because I already have EVO IX Brembo calipers which I will try to install.
I was wondering about 17s vs. 18s regardless of the cost because I see both on "aggressive"/"advanced" track dedicated cars. But I see wide fenders on all track cars. Just trying to plan ahead, so I don't end up buying similar parts twice. But at the same time hesitant to modify the stock body.
The tires you've listed are exactly the ones I'm thinking of buying.

My car has a GTX35R turbo so depending on how hard I push it I should get between 350 to 450whp. For a hard track like Istanbul Park where laptimes are around 2:20:00 I will probably run lower boost/hp for safety.

Enkei has the RPF1 which comes in a 17x10 +38. They have a few in their Racing series which are 17x9.5 at +38.

You can definitely fit 10" wide wheel in front and back without fender flares. You'll have to roll the fenders but it can work:
