Aggressive wheel fitment thread/stance

[EpicTech]

Rear is a 245/45. Rubs the fender liner top-center if I carry passengers in the rear or heavy dips in the road.

That's a tall tire! 1" taller than the 40. I was going to suggest a 3mm spacer if you have space in the front, but I am not sure if that would help your situation because of where the tire is rubbing.

Yea I went taller looking for a somewhat more cushioned ride. Road imperfections make the 40 sidewall just hit too hard and man is it loud. I want to do the same in the front but I got to get the coils raised up first so they will fit. Just having them in the rear is night/day difference.

I wasnt really looking at the neg camber, I saw wheel specs and immediately thought wtf. I already know it doesnt fit UNLESS you have a good bit of neg camber going on. Like you said and I agree, this is not ideal as you decrease the contact patch. I know my car is using all of the 235 width I have afforded it, and that ho still breaks loose if I hammer it. I said elsewhere but with my 18x8.5 +45 Rays wheels, they are rubbing a lot in the rear because I went with a taller sidewall. Was going to do the same in the front but they dont fit. When the car returns from the shop I intend to raise the coilovers about an inch, add in Koni Special Actives in the rear, and then see what everything looks like. Yes I know lower car is cooler, but I want to get away from bust-the-oil pan- on shitty roads phobia.

Yes it has an aggressive camber, like I said in my original post when I had the 18x9.5F & 10R, it’s just a show car and I wouldn’t recommend this set up as a daily or for anything practical. I did get tired of the heavy stretched so wanted a meatier tire. I do have the IS38 turbo and tune also and it is fun to drive, but if you want true sport, the max I’d go would be 8.5” wide wheels et35 with a solid coil over setup. I have the Airlift 3P system, it’s just a build/show car and I’ve had a blast with this car. This is my 3rd GTI, my last one was more “track” built, so I went a different route on my MK7. Hate it or love it, I’ve modded to things I like, whether show, function, or both.

Looking for some info on a wide 245/45/17 RT660. These aren't a daily wheel/tire, it will be used for autoX/HPDE and the occasional spirited drive in the Ozarks.

Tires measure a full 10 inches wide (9.5" tread width) on a 17x9 +42

They were very close (at a ride height, 10-12 mm lower than stock) to the filler neck at -2.5 camber when I originally installed my coilovers last week. I didn't cycle the suspension to verify it would hit, but I assumed it would.
I had an alignment done and had the tech set the rear to -1.3 to give me some more room at the filler neck, but now I obviously gave myself less room at the fender and it pokes due to the wide meats.

Anyone run this tire in that same size? I don't mind running -2.0 camber in the rear, but I'd prefer not to run much more than that to help the car rotate a little better. I plan to try and slide the fuel tank and see if that butts the fuel filler neck up against the "frame" rail a little more snug. If it doesn't fit after doing those changes, I guess I'll do the walk of shame back to Discount tire to have them swapped out for a less meaty fitment.

Pic of how it looks at -1.3

Just a pic for reference to show ride height with my daily wheels/tires.

Apologies if it's already been answered, but has anyone ran 18x9.5 with 235/35? I'm interested to see if this setup would work for track use where I need as much sidewall support as possible.

I remember someone posting that they had that exact sizing/fitment and had 3 degrees neg camber to make it tuck. They had less than ideal contact patch though. Personally I would not recommend running a contact patch like that unless you have a huge wallet for tires every 3 laps.

How much neg camber do you think I'd need to run 18 x 9 +35 with 255 35 18? I'm at stock mk8 ride height. I'm currently at -2.2/-1.5.

Hard to tell. Sidewall profiles / contact patches differ from brand to brand. I fit a 235/40 Bridgestone RE71RS on that spec with I think -2.7°. 255 will generally be wider, but you have to compare contact patch widths on tirerack.

Desmond Regamaster 18x8.5 +45 with a 235/40 Michelin Sport Cup 2s. 12mm front, 8mm rear spacers, titanium floating lugs.

I'll be using RE71RS's.

I imagine at stock height you will be ok but may still want to add camber. I'm not familiar with the mk8 platform, size wise, so it may have plenty of room in the arch. I'd say go for it, just have a camber solution in your back pocket if you need to alter it.

I thought the MK8 had a lot more fender clearance.

Can you go 265 in the front & 255 rear

I think 255 on 9in rim is the right size, I don't think going to 265 will make it better, without a wider rim. Plus, I like running square so I can rotate tires every event.

Biggest concern is the offset.

Time to play around on the offset calculator. I'm betting it'll fit fine, and -2.2° will keep it from poking.
