I am thinking about running these tires on my FD but i have a few questions before I put them on my car.

would you guys suggest i run all 4 of them around or just run them in the rear.

my other tires would be dunlop sp2000's in the front.

does running 2 different types of tires screw of the handeling?

 

I run thew 555's in the rear and the 450's in the front and have an awesome ride. The 555's really hook up well once they are real hot. No noticiabel handling side effects either.
