Ahh ya you can get away with that much drop then. Those tires are almost 2" narrower than the 22s he's running and my 24s I had. 12"+ may rub on the shock housing or inner fender area when it wraps around the shock mount depending on the rims offset. I had about 1cm between it and my 24s. I had a tire explode on my 22s while doing 90mph around a corner and it ripped part of my inner fender out lol. That solved the problem
