Im still on the original kingpins John, but the brake reaction bars made a big difference to the car. On bumpy roads it stopped the chassis shake at the front which meant I now dont have to slow down and like you say the front end crashing on potholes is much reduced. I really should have fitted brake reaction bars before fitting adjustable shocks!
I also now have a Sifab Panhard rod fitted by Matty at Lifes which improved the handling and steering feel at a reasonable cost.
