If they are shimmying, do not buy them. They may not be repairable. They may shimmy forever. Your steering wheel may shake so bad that you think it's going to come apart.
It is possible that the wheel is not round. it is possible that EVEN WITH TIRES THAT ARE KNOWN TO BE FINE ON ANOTHER CAR, they will not be balancable. Is that even a word?
Now I'm sure that if they are not supposed to shimmy, someone will chime in here that thiers doesn't.
There rear 315 drag radials are awsome.
