look at a different brand for your esc other than tekin. Your in texas like me and we know how the heat will destroy a RX8. especially a Gen 2. I personally saw 2 fail sat including one you could have roasted marshmallows on.

And you go to remember that your on very high bite track at mikes. Any tires will wind up being slicks fast anyway. I have raced there.

While a 1258 savox is a good servo. i would not recommend it for a truggy. i have killed 2 servos that were rated for 300oz till i bought a big boy hitec servo. Big wheels make big strain. high traction makes bigger strain.

As far as esc. I run a graupner 180A ultra. Been great for me. Good warranty, Comes with good program card. And i would recomend it. A very close second on that list would be the toro ts150, which i never ran personally but seen a lot of local guys have good luck with them.
