Seems a bit of a twisty circuit, but with some interesting features

track 87 is a very undulating course with 17 corners. the start-finish straight is mostly flat with the track starting to climb midway into the braking zone for T1. from there the track climbs at a 1in 9 gradient through the kink of T2 all the way to the apex of T3, to a height of 70m.

From the apex of T3, the track plummets 35m at a 1:10 gradient to the apex of T4, with the track climbing up a 1:42 gradient to 60m to the turn in point of T5.

from there the track descends to 45m before it flattens at the braking point for T7. on the exit of T7 the track climbs 5m in 25m before dropping 15 through T8&9 before climbing 5m to the apex of T10. track then descends down to 5m through the triple right of 10-11-12. track then climbs again to 10m to T13, drops back down to 5m to T14 before a flat straight to T15. track climbs up to 10m at the exit of T16, before dropping down to 0m at the kink next to pit in.

this is a lot of words so i'll post an image with the math's soon, but here's the blank one now. scale is 1cm=35m, giving the front straight a length of 840m.

Track 88 is a design I really don't like, the rejoin from the road course to the oval was done fairly poorly, there are too many chicanes. the track was designed for formula e and stockcar racing. oval is around 1.5 miles. road course runs clockwise.
