Talk to me like I'm stupid!

Please. I won't even be mad. LOL I'm turning my 2015 GTI in to a dedicated track car. The car is still on stock suspension with a Neuspeed sway bar in the rear and Moog end links. Wheels are F1R F101 18x8.5 et38 with a 5mm spacer up front to clear the Stoptech ST40 brake kit. After the last track day, I took the Michelin 4S tires off and mounted a set of Hankook Ventus F200 slicks 240/640/r18. Now, let me just say I'm NOT surprised the tires are rubbing. But I need to rectify the problem before the next track day.

Options I'm considering are wider fenders or obviously suspension.That's where I need help. I know I'll need to change a lot of parts eventually given the way the car is being driven and to get the most out of it on track but I'm confuuuuused. I'm reading about camber and wheel offset, etc but I don't understand most of it. I'm also going to buy a dedicated set of track wheels but I don't know which ones clear the ST40 kit, with the exception of the Konig Countergram and even those require a 3mm spacer.

The rubbing is occuring on the outside edge of the fender. We removed the screw but haven't bent or removed anything else in the wheel well. Removing the screw did nothing but make it worse, likely due to remnants from the screw removal. The fenders haven't been rolled yet, fyi. As you can see from the pictures, there is quite a bit of poke. The tires are meatier than the Michelins, meatier than I imagined they would be. I didn't understand the middle number in 240/640r18, obviously. LOL

So for those who've done similar things to their GTI's, please enlighten me. I don't care about streetability. I just need to get rid of that rubbing! Would coilovers help? Alignment? Different wheels? Fenders? Which fenders? I'm currently in talks with SRS-TEC but I'm looking at a full four weeks before delivery. Is there a company in the US who sells them? Or a similar width fender? SRS-TEC's fenders are 2.5cm.

What would you do???

I posted this in General MK7 discussion forum that has more traffic so I'm fine if mods wish to delete the duplicate.

With slicks that wide you really need 3+ degrees of camber to get them to fit under the fender. Hopefully you're looking at suspension upgrades as well to deal with the increased grip, and I'd make sure camber plates are a part of that.

your 18x8.5 et38 are now an et33 with a 5mm spacer.
buy yourself some neuspeed rse10 wheels, they have a tonne of brake clearance in them ( i am running 8 piston ttrs/rs3 brakes with no spacers) in an 18x8.5 et45
NOW, having said that i do not know how your st40 brakes compare to my setup but mine are big. going with the 18x8.5 45et rse10 with no spacers the neuspeed wheel would stick INWARDS 12mm more than your et38 with 5mm spacer.
also, like someone said, tires like that like negative camber

I agree with the rse10 wheels, they are designed to clear bikes. I would definitely say you need to up the camber if you're running slicks to probably -3.7 or -3.5. Whats your budget for a dedicated track car? If its pretty high, get the verkline suspension catalog. If not, get super pro bushings all around, decent coilovers that come with camber plates and some css knuckles. Running slicks will really expose the weak points in a car.
