the easiest way to get some lift would be installing spacers between the top of the shock and the shock tower, front and back. i would start examining those areas. There are no pre configured kits that i know of for this though. if you are trying to do anything more than an inch you will probably not be able to get the car aligned with the stock suspension.
another easy route is installing oversize tires, that alone can get you an inch of ground clearance with minimal side effects. just have to keep in mind that the speedo will be off by the % you oversize.
