The KW clubsports utilize a helper spring, and the spring perch sits lower than most. The 18x10 et25 front wheels will need 5mm spacers to clear the strut. Your fender clearance will be no problem with 275's (depending on compound, ride height etc.), and negative camber will add even more fender clearance. I would go for 275/35/18 front tires, and 295/35/18 rear tires.

As many members have already figured out, you can ditch the helper spring and swap out the spring to raise the strut above the tire. If you perform this spring swap, you will not need to use spacers.
Thanks a lot for the answer ;) !

I've ordered a set of ec-7 , I Will post some pics here ASAP.

I can't wait to put some tyres on it and see how it looks on the car :) .

I know Apex wheels are very light but I was really surprised when I hold it in my hands.
The weight difference between the Apex and OEM wheels is so huge !
Here is my setup;

Front: 18x10 +25 (12mm Spacer) 265/35 Conti DW
Rear 18x10.5 +27 (15mm Spacer) 295/35 Conti DW

Hello,

Some pics of my freshly fitted Apex ec-7

10x18" ET25 ( with 5mm spacers ) on the front.
11x18" ET25 on the back

Tyres are Michelin Ps Cup 1 in 265/35 and 295/30.

The car is lowered on H&R race (red) Springs , IMO it's now too high , KW CS are coming soon :) .

I really like how the car handle with those light wheels !

Square setup? What offsets? Sorry for all the questions really trying to decide on 18 or 19's!
Got my new Arc 8s in 19x9.5f/10r installed the other day, lowering springs to be installed next week

Wonderful setup. Did you have to roll the fenders?
Does anyone have any pics of an ARC 8 on an e90, in 19's? Preferably 20x10 all around.
