They are the ones! was hoping you would spot this and reply! I know one of the sets I have seen were suffering but not seen your car for awhile so wasn't sure but was hoping they were still ok!
What size tyres have you on yours lowey?
I am tempted by some 255 as my avons 225 don't seem to be gripping with the SC.... though switching to toyo might help.
So yeah if you get it SC'd you might want some new rubber more expense! but worth it!!
