bump
i have zero interest in horses, but ill happily take the day off
spent ~3 hours sitting in my boot with some scissors and a roller - took the time to ensure very little overlap bw sheets to reduce the weight and product/cost
in total i have dynamat'd under the rear seats and now the full boot floor and it's done wonders for reducing the amount of exhaust boom, road noises and random r35 drivetrain creeks n groans
imo the boot had a much bigger effect then under the seats, so if anyone wants to give this a shot, start there
the die hards will snicker at the weight gain, and fair enough if you're an unmasked stig. Ive used roughly 6kg so far, but imo well worth the weight penalty (which ive compensated with a carbon trunk, ti exhaust, forged wheels etc anyway)
