There are metal valve stems and i paid them 240 for it so i hope i have them.

The reset is basically start the car, turn it off wait 15 min then drive 15 miles. So basically just drive it. Im wondering if there is different types, like that operate on a different frequency. Ive searched a bit on google but seen nothing obvious about it. I just need to go let them figure it out.


Edit: Discount just confirmed to drive it and that there is 2 different frequencies 415Mhz and 330MHS(I think it was 3 something). So I'll just go and have them scanned for function and frequency when I get home. Sorry for bringing it up. I've just been lazy then saw you're build was early and kind of close to mine.

All RX8 have recommended tire pressure of 32 psi (all four tires) , measured when tires are cold ( not heated from driving). You only change from the recommended psi if you are racing and need different balance and/or traction on the track, or carrying an overload weight (not recommended for your suspension anyway.). Adjust your pressure as the outside ambient temp goes up or down.

No rocket science here, very simple. 32 psi, all RX8s.

lol, yeah its really simple. street car needs the PSI on the sticker, with cold tires.

a good start for a track car is the PSI on the sticker hot.

good start for a track car is 32 psi, then after you first session measure pressure and bleed to 40psi. if tires are less run next session and see if they come up. track sessions seem to work best for me at ~ 39 to 40 hot.
