Looking for proper offset for 10-11" set of rohana rxf11 285/30/20 fronts 305/30/20 rear. Available offsets are +25 or +38 front, and +28 or +35 rear. First time trying to calculate for offsets is frustrating to say the least.

Any help would be much appreciated.

Not our brand but im willing to help out a forum member any time.
considering the off sets that they have available for you there is no need to calculate as you only have 2 choices for front and back/

front 20x10 use the 25et

rear 20x11 use the highest they have which is a 35et but it will be aggressive because on a 20x11 is ideal to have a 43 off set meaning if you look at the picture below there wheel will be further out by 8mm

this car has a 20x11 43et
just to give you a idea.
if you do a 35et you may need a 295 to avoid any rubbing but will also look a little stretched

**** important **** also check with the manufacture to make sure it clears the caliper system on your car, you can have a 20x10 and 20x11 with the perfect off sets and be camaro direct but the design of the wheel sometimes will not allow to clear large piston calipers. ive seen some brands do replicas and still cant clear lol

Thanks for the info I was clueless.. It was actually a hard decision between rxf11s and mrr755s.. I wasnt in a position to wait since someone put my car on blocks last week

Got them gorrila x2s locks, and a blackboxmycar kit going on with the rims this time

You also need to take a grinder to the end of the rear axle and take off a few millimeters.... in order to get the center cap on correctly, on an RXF11.

Edit: it was an rfx5, not the 11...

Thanks for the heads up bro. Got a cordless in the trunk since I just did my headers

I would definitely email them. They got me the +35 in the rear and +25 in the front. Same tire specs.

Yeah that's what I went with. Did you have to shave axle for the center caps??

No they fit just fine

My bad, I had to use a grinder on an RFX5, NOT THE 11.....I've had a few sets of wheels since then…
