    325ix adapter convertion to 5/120

    I want to know which adapter is the one i need. I got a 35mm offset 325ix, i want to fit a set of staggered Style 32 7.5 front, 8.5 rear, but wheels offset are 41mm. Any help guys? What width must have the 4/100-5/120 adapter to have the correct look in my car.

    I also found a set 17x8 17x9, with 20 and 26mm of offset, will this also fit with an adapter?

      you must do the calculations yourself just like i did before I ordered my adapters.

        hum the less i can get for an adapter to 5x120 is 18mm, so 41mm -18mm it will give a 23mm offset, but i dont know how it will look that on a 325ix, but i do know 23mm will be good for a rwd e30.

            Your ix is not 35mm offset. The stock 7" ix wheel is 41mm offset. So using an 8.5 wheel with a 41mm offset, the wheel will stick out the extra .75"(19.05mm). Add an 18mm spacer and the wheel sticks out a total of 37.05mm, versus the stock wheel. That's huge poke.

            Using the 318ti rear end you can have 5 bolt in the rear of an ix, and in the front I have found a normal e36 rear hub will work in the front ix strut/bearing, with barely any change in offset. The only problem is the brakes. I have a set of e30 m3 rotors and calipers, but the brackets do not fit, and making a simple adapter is not the solution. The caliper bracket itself needs to be machined and it could get dangerously thin.
            the other option is using another caliper from a different car where a simple adapter could make it work. I think a 96 Volvo 850 might work, but I can't remember, its been a long time since I looked at it.
            With some minor turning on the hubs, they fit the e30 M3 rotors nicely.

            Using the E30 M3 rotor gives the only rotor-to-strut clearance that I have found. Everything else either requires a hub with more protrusion, or contacts the strut housing or tierod. Look for yourself, its not simple.
            If I can get my hands on an 850 caliper I will try fit it to my strut that has one of my e36 hubs installed.
            Caliper aside, I have bolted a 17x8" et20 style 5 wheel to my strut with the e36 hub and m3 rotor. There is room for the caliper, but it is not easy to fasten the bracket.

            3.0L ix stroker comes first though.
