Lift springs?

[j-san]

Unlike the majority of folks here, I am interested in slightly lifting my Yaris. I plan to be driving it year-round and the winters can get messy and snowy where I live. I also make regular trips to a friend's cabin out in the woods so I will be doing some minor off-roading and driving on dirt trails. I think a little bit more ground clearance would make for a pretty capable little car - like the Subaru XV, which basically is a lifted Impreza.

I only see aftermarket lowering springs available, but are there aftermarket lift springs or compatible springs from another car that would gain an extra 1" of ride height? Can the stock shocks and struts accommodate a lift?

Thanks.
