Welcome!!! Sounds like your suit will be fine. Don't worry about upgrading yet.....let the addiction take care of that...lol. You will find many "I have to have X....Y....and Z" before your done with your first weekend. The good thing is 90% of it you can justify by saying, "It will make me safer". It's the upgrades that you find yourself saying "It will make me faster" that you should avoid. Nothing will make you faster than seat time. You can buy a season pass for what a suspension upgrade cost and unless you've maxed out the capabilities of the stock suspension, an upgrade is pointless. I know lots of fast people who can smoke 95% of the riders on track with a bone stock R6. Priority #1 safety. Priority #2 seat time. Priority #3 performance parts. Many people get the #2 & #3 priority mixed up and can't figure out why they are not advancing on their $20,000 R6. Riding a variety of tracks and a Quality School like YCRS will do more for you than Ohlins or a set of slicks will do.
Also, don't be afraid to tell people you are new. All of us were there at one point and everyone likes to help new riders out. The people parked next to you may just become your closest friends soon so ask questions. The staff is interested in getting you on track to have fun and be safe. They will do anything humanly possible to make that happen both in tech and registration to on track coaching. Bring plenty of water and food. Dehydration can end your day in a heartbeat.
