FC w/ET Streets
 
I was wondering if anyone here is willing to share some tire pressure data when using MT ET Streets on an FC with stock rear suspension.

I was looking over the MT website and they recommend 8psi and up for cars weighing 2500-3000. The lowest I have gone so far is 14psi.

I am curious to hear if lower is better with a relatively light FC.

Thanks!
Andrew

Every car and track combo is going to want a little bit different pressure. Start dropping your pressure till (A) your 60' times start to slow (B) the car starts walking around on the top end. 8 PSI seems awful low to me but i am use to a little heavier cars.

I will be at the track on Saturday and I plan to do just that. I realize all tracks and all cars are different. I was just seeing if anyone had any real word experience and success with a starting ballpark. 8psi seems pretty low to me as well, but as long as MT says its safe, I am OK with trying it out. Since adding bias-ply front runners the car goes straight down the track. No more tail wagging drama.
