Spacesaver on Front?


Having damaged one of the GT's 17" alloys in a pothole, I need to use the spare spacesaver wheel for a couple of days while I get a new wheel. I'm not planning to do much driving with it - just a few commutes to work (about 7 miles each way.)

It was one of the front wheels that got damaged and for the moment I've done a straight swap with the spacesaver. I don't have much faith in how much grip the spacesaver will offer, so I'd much rather keep it on the front so that if it does break traction then I'll get understeer. However, the spacesaver is a much smaller diameter wheel, so I wonder if there's any risk of damaging the diff by running with different sized wheels on the front?

The manual makes no reference about not being able to use it on the front. However I've seen a few forum posts that suggest it's not a good idea (although there's also others that bring up the whole understeer/oversteer argument.)
Does anyone know if I run any risk of damaging the diff with keeping it on the front?

Yep there is a risk of damaging the diff although you'd have to be quite unlucky. Most car manufactures advise that you move a good wheel from the back to the front on a front wheel drive car. As the car is front wheel drive and in theses current conditions especially I would really suggest you move it to the back. I see your understeer theory but far more load goes through the front wheel than the back interms of breaking and cornering. The car is far less likely to slide out control with the space saver on the back in comparison to having it on the front as trackion is far more reliant on the front wheels when cornering. You would be more likely to have an accident the way it is. Hope you get it fixed in tiem for christmas! Hope the info helps too.
