you miss understand what this board does for you as a racer. This thing does not fix a chassis is has a perm tweek to it or a bulkhead that is bent. If you race and never hit a board, then this product is not for you. But here at the IIC, I have not seen that racer yet. I believe that all the top 10 guys have had a few "Board meetings" this week.
this week board is made to help fix a tweek in the car from a board hit. You loosen all the bulkhead screws and all the top plate screws. then you bolt your bar to the plate and then you tighten all the screws. remember that even though all the bulkheads, top decks and chassis are flat and straight, it does not mean that you can not induce a tweek into the whole arangement.
but to each his own. if you drive a tweeked car and enjoy running a tweeked cars. and if you like to leave it tweek and possible cause the entire chassis plate to set in that twisted mode, then this tweek plate is not for you. can you resolve these problems with a standard flat board? yes, but you will need at least 3 hands to do the same thing this tweek boards does.
