Ooooo. Yep, different sizes. The tallest they make for the rear are dot 4 where you can get a dot 5 for the front. I ...... dare I admit it ........ why not. I sliced some spare dot 3's and put them under the dot 4's to raise the rear and went racing. DUMB! But nothing bad happened. Then I just "did it" and went with the K&W's. Just so you know, if the 4's are still too short you can work around the problem, if necessary.
