blocks
The 414m one dot gives you 1.5 degree toe, the 414m double dot that surikarn uses on his M gives you 2 degrees, but the optional blocks for the evo2 give you the additional choice of 2.5 and 3 degree. Could be a margin of error of 1/2 degree. because with my hudy stuff I thing stock toe is 1 degree rear and when i use the M one dot block It gave me 1.5 degree toe. I agrre they are nothing new since I have seen TRF drivers use them, but the sway bar and block kit give you more options then just using the M blocks that are available.
