Testing at Brands

Had a day at Brands and had a few problems with the car but we got the front suspension adjusted OK and did a few laps. I discovered that one of the front hubs I fitted has a bent plate which causes one of the front wheels to wobble so I need to sort this out before the first race.

Here's a pic in the paddock showing the dream team - Charlie left, Joe right.

Some technical stuff: We set the front tracking to 1.5mm toe out measured at the tyre wall. I drove with the dampers set at full stiffness and the car kangarooed down the straight at Brands. Then we went for half stiffness with an improvement - the car felt less inclined to power slide on exit from corners. We finished the day with the car set at 25% stiffness - halfway between fully soft and the mid point. The dampers have 18 clicks of adjustment on the front and around 44 clicks of adjustment at the back. For the front we wound 14 clicks back from the stiffest setting. On the back we wound back to full softness and added 10 clicks.

We set the front and rear ride heights roughly but need to take a measure from a point on the ground to a point on the car to make sure this is accurate. Currently I feel the rear suspension is too low, we'll test this with the thermometer which should tell us if we have too much camber.

Thanks again to Joe for taking notes.
