Great to see you had a lot of fun!
DE is indeed the next step. You will like it even more as you will add speed to proper car handling. Looks like you used quite a bit of painter's tape to protect the car. You should be OK with Clearbra if you had it installed. Just be ready to replace it every 2 to 3 years.

Saferacer.com can be another good source for gears online.

Keep enjoying the car!!

 

Glad you had a good time! It is a great way to spend a day! Especially if you get weather like today.
