Use the standard 25mm M5 bar at the front plus the 20mm rear bar from the Euro M5T. You can get both from BMA - I paid ~U$105 for the 20mm bar this spring. This, combined with OE rubber bushings (buy at the same time from BMA), will give excellent handling and counter the E34's penchant for understeer (thicker rear bar is the trick here). The standard rear bar for the M5 is 18mm. All of these parts will fit in the standard brackets and such. Note: don't try to re-use the rear bar end links - buy new ones.

Also, avoid staggered tire sizes (larger rear width) unless you're making stupid power - wider rear tires increase understeer.
