Hey great build mate. First you let an 86 past you haha nah. Go out to wakefield heaps in the formula fords when im training drivers and with the race team. Only tips really i can see from that short video.
1. The 'Kink" before 1 at that speed should be able to be taken flat then straight after hard hard on the brakes aimaing the car to the outside of the entry to T1, downshift in the straight line while braking and then hook her in. (depends on how good your brakes are of course but most cars with decent pads i read you had issues on the day. back to 3rd or 2nd depending on how deep you go in.
2. The left hander going up the hill way more speed can be carried.
3. Turns 3 and 4 at the top of hill can also carry more speed, good lines.
4. the 'Fish hook or T5 and 6 pretty good through there. Maybe can take more ripple strip on that right hander sweeping. and same rule as T1 aim for outside of entry then hook in for a later apex carry more speed out.
5. Other then that the lap looked good obviously had to let the other car throigh which stuffs the lap
P.S You know you want the 32
