jajajaja yes! i know what you say.... another owner of a Supra whish started a track Supra years ago had a bad influence in mine !!
I know how that goes, I blame my buddies Andrew and Clint for getting me into these cars in the first place. My project is a fine line between street car and track car, so it is a LOT heavier than yours, but it makes a great road trip car to get to far away tracks, so it works out. It's difficult though, with a dual purpose car. Track only, sacrifices of comfort are easy to make as it will make the car faster... you understand I'm sure.
What am I looking at in the passenger side foot well? Looks like a hydraulic reservoir of some sort. Remote brake booster?
what did it come in at?
Yes, you could be hitting the 1st or 2nd harmonic.
Have you used the calculator to check this?
Also what are your driveshaft dimensions?
1 piece / 2 piece ?
