In my opinion before adding a racing game like this you should first fix your servers. It's ok to have 300-400 ping in normal events but racing is all about incredibly low ping and detail.

Also the tier points are astronomical, I would love it if it was a normal event like ursoth, Halloween etc which is better to have high tier points, but this racing is difficult for many players and very tiring to play for long periods of time.
Anyway that's my opinion
