    For those thikning about a modded GPR ride plate

    What a difference....My Jims FF plate has been on all season. I put the stock ride plate back on my GPR (12r) to do some Lake Mi riding and decided to keep it on to see how it would run in flat water.

    The FF plate was 5.1 mph faster on a back to back test. The only time that elapsed was the switch over (15 minutes). I MAYBE could of picked up .5-1 mph with the stock plate if I removed the washers from the trim tabs but I like the planted feel of .100 under the tabs.

    I have previously used the FF plate on Lake Mi in 1-4 footers the stock and FF plate had very little difference when the rear of the FF plate was dropped down .150 (get longer bolts).

    Needless to say after all the $$$ I have thrown @ this thing the ride plate was the best purchase.

    as long as jim does the centre section mod it will handle in the chop and with your speed angle too, without putting extra in at the rear.
    if it was no good in the chop i would not run one off the coast of the uk,its no tropical paradise here MEGA CHOP CITY.

    Everytime I am in weekend chop/slop I just throw a couple of washers in the back of the plate. It takes all of 5 minutes and is a great compromise between speed and handling.
