Possible Motor mount issue

[friday]

So yesterday I installed IL motorsports mounts on my car. On the way home I notice that when I hit the gas the can pulls to the left and when I let off it goes back towards the right (or visa versa, I can't remember). Does this seem like an issue with motor mounts? The other things I did to the car were change the oil and flip/rebalanced my tires. I really don't see the tires causing this issue because they were fine before hand. One of my old mounts had broken in half and the car did not have this issue before the new ones went in. I might not of bolted something down all the way.

I am going back to the shop tomorrow to recheck everything.

One other thing to note is that I cut my right rear tire yesterday and I am having to use one of my old hollow spokes as a spare till I get another star spec. So I have 15 inch wheels all around and one 14 inch.

And yesterday did blow. Ruined a good tire and my car feels like shit.

What is the tire size of the 14 vs the 15 and which corner is it on? That could have something to do with it.

The 14 is a 195 or 185/60/14. The 15 is 205/50/15.

which corner did you install it? do you have a Torsen LSD?

Passenger rear, I do have a torsen.

Your torsen is trying to even the speeds out between the two different sized wheels/tires. That's why it is pulling like that. I would bet the tire pressures might be off, too.

Put the spare up front and move the 15 in the back.

There is a slight difference in PSI, but only a few pounds. I know the star spec has a much stiffer sidewall than the toyo 400 tread wear all season.

Thanks for the help KFJ. I will probably just throw the rest of my hollow spokes on till I get a new tire.

good plan.
