Default Offset question

Hey all, I tried using the search function for this question but I didn’t really have no luck. I have an 08 isf slightly lowered on KW V3’s. Thinking of buying these wheels but not sure if it will clear.

Gram Lights 57DR
19x9.5 +25 19x10.5 +35 5x114.3

If there is anyone who already has experience with this please feel free to chime in.

thanks all.

Same offset on my isf but my front I believe is 9 not 9.5 will run when you turn your wheel all the way and depending how low u are it will rub so u might need a roll in the rear but if your not too low think u b fine

It is too aggressive without fender/camber mods. I have 19x9.5 +38 all around, 265/30/19 tires. Lowered on coils. rears have to be rolled/shaved, front is fine. I have -2.5* rear camber (figs rcas), -3* front (figs fucas). A 10.5" wheel with +35 offset adds over a half inch of poke from the hub towards the outside compared to my setup. For the front, you are poking the wheels out more than 1/2" more compared to my setup again. In other words, totally doable, but will be a fairly aggressive setup.

Here are photos from lowered on coils, no camber mods.

Those offsets are 20mm (.78") more aggressive than stock front and rear on 1.5" wider wheels. You will not be able to run wide tires and will likely rub without rolling the rear fenders flat at a minimum...and even then you will still likely rub without camber if you are lowered at all (unless you mount skinny tires). If you value "flush" over performance and don't mind modifying the fenders & adding camber, then you can make it work.

What’s a safe number to run on offset which will guarantee a fit. It seems a higher offset +35 will more then often work out.

I run a 19x8.5 front and 19x9.5 rear. Front et30 and rear et40. Tires I’m running are 255/35/19 front and 285/30/19 rear. If you want wide tires you can’t go with a crazy low offset. Your car will look weird with rims that poke out further then the body. Plus to make it work fit skinny tires on it that will diminish performance.
