I'm currently looking for a space saver my car I have been using a roadmaster sedan full size aluminum spare but with my 8 cube sub box in I cant get it out the spare tire well without deflating the tire
didnt know boxy spares fit i think there might bean abandoned box still at my dads auto shop parked next next to and abandoned SLS I keep begging to to get the seats and console out of lol
I have a full size spare on an OEM aluminum rim and it does not rattle around at all. I wouldn't want a small donut. When I bought my wagon from Fred he upgraded the car to a full size spare for me. It is a tow pack car with posi but it originally had a donut.
if you have a posi and want a space saver you have to make sure the hieght of space saver is the same hieght as the tires on the car. if you have 2 different hieght tires on rear it will wear the clutches out in posi real quick
