Jason Drew's car feels great with a solid rear. I haven't been in a solid front but I imagined the upgrade in cornering stiffness would be worth it. Why don't you like your fronts Ian? And anyone consider a corrosion issue due to 2 different metal types reacting ? A problem that wouldn't exist with a super stiff rubber.
Use lube/anti-seize and you should be okay - I wouldn't put the bushing in bare (even if it weren't aluminum).
