[Cobra #3170]

Thanks Tommy and Ron, the America Autox Series is on an abandoned air port and they set up a test course on one of the runways. The course is marked with paint so it is always the same and it has its own dedicated timer. For $20 you get 2 hours of testing time which is an amazing deal. We usually sign up for 4 hours of testing at a time and just park the trailer at the test course and run the autox (which is different every event) when our class comes up. I have set up sheets where I record everything done to the car every time we run right down to installed spring lengths so if we get lost we can always get back to something that works.
Scott is such a good precise driver that we can immediately see if a change is better or worse and sometimes it is an improvement in one area only and not overall time. We save all the electronic data from every autox so we can go back and review it.
Yes, we make multiple changes at a time but have done so many different tests we have a pretty good idea of what will help a given problem. The car is getting so good now that even my worn out old a$$ is beating many of our competitors and Scott is always at least 2 seconds faster than me. We usually both make base line runs then sit down and review the data and mutually decide what to do. Goals are at least 1.3 G cornering,
1.2 G acceleration and 1.5 G braking and of course over all time. Two weeks ago we met everything but braking. Our maximum decell was only .7. After the master cylinder and pad change we are 1.0 but still a long way from 1.5. That is our weak point right now so we are looking at knock back springs in the front calipers and possibly replacing the 2 psi check valves with 5 psi. I would not try this on a road race car but for 1 lap stuff think it will work. Another critical point is ride height we have found the front of the lower frame tube needs to be 3.00" and the rear about 3.250. If the car under steers we go up to 3.375 if it over steers we drop it to 3.125. This really allows some quick fine tuning because you can do it on the grid and just count shock collar rotation.
Once the brakes are fixed we will start shock tuning to see if there is anything there and what happens when you make a big change.
