This is just my opinion so don't get pissed and e-thug me but I'd ditch the front brake, cut the flanges off the grips and get a pivotal seat setup. Do you really use the front brake anyway?
There's no point in having flanges unless you bar, actually there's no point in having flanges at all. A pivotal will look way nicer and save a good bit of weight and on a so called 'street' bike a front brake is pointless unless you're doing mad adam banton style shit.
