Wheel fitment issues with Apex EC-7 (or not?)
Hey guys, finally pulled the trigger on a set of Apex wheels. They're standard EC-7 1 series fitment, 8.5 ET45 and 9.5 ET 58. Spray painted them yesterday and they look amazing on the car. The only issue I'm running into rn is the lack of strut clearance I have in the front. the wheels and the tires are not touching the struts when I look at them lock to lock but the clearance is very marginal. I put some painter's tape on the struts and went for a drive. they came off seemingly untouched. However, The car's making this scraping metal rubbing sound periodically whenever I make a left turn as if there's a point either on the wheels or rotors/dust shields that rub against something every time it comes around. Do you guys think it sounds more like wheels rubbing against struts or it sounds like something else?

I am running EC-7 18x8.5" ET45 in front with 235 Hankook RS3s there is maybe 1/2 inch of clearance between the tire/rim and strut, I have driven on the track hard and no issues of the tire rubbing.
I am also on stock suspension and no wheel spacers. |

You talk about the wheels, but what tire size are you running?
I have the same wheels, had a small rubbing problem on the rear at first. Turns out our old alignment rack was off. Did another alignment and dialled in a little extra rear camber fixed that. I run 245/35/18 front, 265/35/18 rear. Many people try and run the 235/40/18 in the front, but that is a fair bit taller than the stock size and can rub on the fender liner/bumper tabs. Not an issue with the 245. |

OP, typically our 18x8.5" ET45 and 18x9.5" ET58 wheels are a direct fit on the 1 series, but there are some factors that may affect clearance.
Typically 235/40-18 and 265/35-18 tires are a direct fit. Going with a 245/35-18 tire up front would require a 5mm spacer and a touch of negative camber up front. In the rear, a 275/35-18 tire can work, but would likely require a fender roll. Suspension type may also play a factor. What tire sizes and what suspension are you running on your car? -Matt

On my last car, if I turned the steering wheel all the way the brake lines could push the dust shields just enough to hear them on the rotors. Might be worth a check to be sure something didn't get put back wrong the last time work was done, or you have a broken clip or something like that.

Quick question regarding this, hoping someone can chime in: what is the handling implication of going 235/40 vs. 245/35 up front? |

The 245/35 will allow for slightly better handling, especially when paired with the 5mm spacer required and some negative camber dialed in. This additional grip and alignment change will provide a crisper turn-in and a slightly more stable car under braking. This comes with a small sacrifice in ride comfort over rough surfaces. I hope this helped! - Max

I just put the same setup with my new EC-7's, using the 235/40 front, and I am getting some rubbing on the outer shoulder of the tire, just down from the tread where it rubs on the fender.
It's only on the right side, and typically when the suspension is already compressed (in a left turn) and I hit a bump. I am pretty sure my right strut is toast though, so when I put new struts on next week, I am hopeful it will alleviate this problem. Next set of tires I will probably go with the 245/35 option (with spacers and Dinan camber plates). I'll report back on whether the new struts (Koni yellows instead of shot OEMs) fix the issue. FWIW, I have no additional negative camber beyond factory spec at the moment. Planning Camber plates and M3 front control arms in the future.
