Talking Help: wheel offsets

Im looking to purchase a set of rims with these offsets. Im currently running Bilstein Sport shocks with Espelir ASD springs. Can someone tell me if this will be doable on my car without fender mods?

20 x 8.5 front with 25mm offset & 20 x 10 rear with 25mm offset

thx

Nope

For those rim widths the most you can go is +32 Front and +35 rear ONLY by modifying the inside lips.

For no fender mods you need to go +38 Fr & +44 for no rubbing at the lowest drop settings.

Sure it's possible depending on tire size, brand, camber setting, etc.

Comparing 42 to 44 is barely of 1/16 of an inch so the tolerance stack of all the other factors mentioned will determine if you could rub.

+44 is a conservative value that would guarantee no rubbing in most any set up, including with 4 people in the car and a trunk full of luggage going over a freeway bump going 60+ mph.

Why don't you roll the lips? It's clear to me, you heat up the inner quarter panel lip and roll it. It's simple. I should have a lexus owner lip rolling day at my place and let everyone use my fender roller. Don't be afraid of the lip on the quarter panel. If you are doing a flair, then you need some experience.

RMMGS4 - I have also found that once the lip is rolled and the wheels are tucked, the lip doesn't hit the tire (depending on offset), it's that upper lip in the wheel wheel. It needs to be hammered flat.

Yup that will work, but I was originally answering GS3.0 's question about his +25 offset, which won't clear even with a rolled lip.

Sounds like he wanted a wheel offset with no fender mods.

Yea, im running 19x8.5 and 19x10.. both with a +35 offset.. my rears dont rub too bad anymore since i rolled the lip, however, they still rub on corners and hard bumps, and my coilovers arent all the way down yet.. The fronts rub too.. but not too horrible.. im gunna downsize my tires from 245 and 275 to 235 and 265... a but of a stretched look, and less rubbing.

Try to compress the suspension all the way down, or drive up on a curb/2x4, to compress it. I am almost positive that you are not hitting the fender lip, you are hitting on the upper lip right above the fender lip. Pull the wheel off, jack the car up, take a heavy hammer and hammer that ***** flat. You will see a difference.

I am running a 20x11 +41 and it cleared the fender lip after I rolled it; however, with full compression the tire would hit the upper lip. After I hammered that lip, it was gone.

Good Luck and congratulations on not being scared to roll the lip! (I have a thread in the tire forum ranting about lexus owners being afraid to roll the lip).
