Front spacer size recommendation

[20ducks]

What size is recommended for the front? Also a source for the recommended front spacers is appreciated.
I have 20mm spaces in the rear.

For what wheels and tires?

I've been out of town, I'll get the size etc later today.

I've had a few different combination on mine. Ended up with 23mm at the front, 20mm at the rear. Eibach pro lowering springs. Perfect for me, sit's real nice. Excuse the gloomy photo, but you can see how the fronts sit well;

For what wheels and tires?

Sorry for the delay.

255/35 20 use stock wheels for reference. Also have 25mm spacers in the rear...no lowering springs, front has SR Performance Sport Lowering Springs.

My guess is 15mm spacers for the front??? Pure guess. Or what do you think would work better?

use stock wheels for reference.

you mean like 18x8.5 wheels and their native offset for reference? Seeing as how you have 255 width tires now, I doubt you're still running 8.5's. We need your ACTUAL wheel size and offsets to answer your question.

So you dropped the front by 1.2" but left the rear reaching for the sky?

The rear would have rubbed if the lowering springs were installed. The front tires are: 255/35 20 use stock wheels for reference for offsett. Also have 25mm spacers in the rear...no lowering springs, front has SR Performance Sport Lowering Springs.

The rear would have rubbed if the lowering springs were installed.

Then there is something wrong with you setup. Either the 25mm spacer is wildly inappropriate or your 20" wheel offset is not what it should be.

The front tires are: 255/35 20 use stock wheels for reference for offsett.

There's no less than 4 different wheel arrangements from Ford. Which "stock" setup would you like us to reference? Let me help. Kindly pick the one that matches what you have.

Tire width and offset are all you really need when tire width > wheel width, so ..

20mm spacer should be fine.

Thank you. That is all I need.

Sometimes when you ask a person "what time is it?" they proceed to tell you how to build a clock.

Or go outside and look at the sundial yourself?

You'll be back here in 5 days moaning about how you have tire rub on the front. When you ask a question and refuse to provide the necessary datapoints, don't expect a helpful answer.

Go pull the rim and look on the backside for the wheel specifics. Or create a plumb-line and measure the inset from fender lip to tire. That's approx how much spacer you can use.

Okay.

I have a 2020 gt premium with 18x8.5 & Im buying the same size wheel but with a -35 offset. Standard spec tires. I want to buy spacers but unsure of I should buy 25mm front & rear or different sizes. Just looking for a slight better look. Also, would I need to get the alignment done after or would it not change anything? Thanks for any suggestions
