Default Square 18x8 48mm+ - Is offset okay?

Hello, looking at some Looking at a deal on some OZ Ultraleggera rims for a winter setup.

Does square 18x8 48mm+ work on our cars? Wondering if you would hit the strut or shocks with such a +48mm offset

Offsets will be more than fine. As reference, a few guys and myself are running 18x9.5 et 40-45 with zero clearance issue. What tire size were you considering?

225 on all corners? That's super narrow. Is this for an isf?

I would think you want super narrow for a winter setup. Carves easier through snow.

with VSC and TRAC off, the ISF is a blast in the snow. I'm on winter #3 with the ISF as a daily driver. I also run 225/45/18 on 18x8 wheels,, I think the offset is a little lower on mine tho, possibly +45.

one thing i envy from california is the weather but dislike everything else lol anyways back on topic. my wheels are 18x8 40+ and they work fine. i also take traction control as it is a little intrusive when it loses traction but not as bad as my old is300 used to be. overall the car handles really well in snow.

does any one have this issue in snow when you come to a complete stop and the car moves a little bit forward?

I run 225/45/18 in winter, they work fine, the only issue I have in winter sometimes is when the car is cold and I'm at the stop in drive , my rear wheels start to slip with the brakes on, I have to throw it in Neutral in first few minutes until car warms up and my Rpms drop a little.

The first time I winter drove the ISF this caught me by surprise. It seems like the brake-bias is heavily biased towards the front.. so at normal brake pedal pressure the front wheels will lock up and hold the car.. but its not enough brake force to hold the torque from the rear wheels back, so the rear wheels drive thru the brakes, and skid the car forward on the front wheels.
If I go hit a drive-thru for coffee or stuck in stop n go traffic, sometimes I'll just put the car in neutral, just to make sure it doesnt skid forward.
