Shifter karts are considerably faster than anything your going to ever bring to the track. They'll teach you alot.
again its not about speed....
quote from a local forum when the cost of tracking vs. autoX and other events came up.
What you need:
SA2000/MA2000 helmet or newer.
A car.
That's it.
A quick checklist for Mission:
-Shoes that fit properly
-Gloves can be nice if you're prone to sweaty hands
-Check your brake pads, is there a lot left? Mission is brutal on pads
-Bleed brakes, make sure the fluid is pretty clean looking. Basic maintenance, I know, but once again, Mission is brutal on brakes.
-Water. Long track days are thirsty work!
-Remove hubcaps/center caps or you WILL lose them (I did :'( )
-Show up with a full tank of fuel. If the track has fuel odds are it's like 116 and you can't afford it
-Bring oil (especially for Honda lol)
-HP means nothing if you suck at turns. Spend your money on tires and brakes. Engine mods will be more meaningful later, I promise!
I challenge you to try it. If you end up having a really good time there are options for amateur road racing available in the northwest. I'm exploring some of these options myself. Track days/HPDE are nice because you just show up with what you have, have a great time chasing your buddies around a racetrack, and then go home. Road racing is a lot more dedication, a lot of planning, and a substantial investment now that your car MUST meet certain build specifications/safety regulations - Not to mention one bad move from a competitor can erase everything you worked so hard to build. Laguna Seca is the best racetrack in the universe but I'm just a regular Kelowna-job-sunshine-taxed kind of guy and California doesn't agree with my bank account.

Anyways, I hope this helps. Surely I'm not the only one on KCL that's done track stuff with input to add here....
higher power vehicles...
