Well, your making more hp and tq than both cars but in the case of the 95 not much more. (hp that is.)
I'm not sure of the weight of the bimmers but assuming your car is healthy I don't think you should have any trouble taking them.
If you have money for an upgrade, changing the rear gears will do the trick.
Is your car stick/auto?
