looking at getting some 15" Rota Slipstreams for my 2000 integra LS to improve performance, especially handling. what is the widest i can get away with (6.5, 7, 7.5), and what is the smallest offset i can get so my car will have a wider stance(40, 35, etc...), or should i stick with my stock LS mesh or some other cheap light rim. tire opinions would also be appreciated (looking for grippy tires with decent life, and acceptable rain control for a reasonable price. also do i run the risk of overdoing it and getting something too good as to overstress the suspension

thanks
