for a 2WD SCT in mod, I would probably go with a 6.5T to 7.5T motor, check out RCJuice under their Rocket brand of motors, they're pretty good for the price. RCJuice also sells JX servos which are decent for about a year or so. Most brands of servos will generate slop over time as the gears slowly wear out. Unfortunately there are no replacement gear sets for JX servos making them disposable. If you want a quality servo that will stand the test of time, then I would pick a brand that offers replacement gear sets. I run mostly Savox servos in my cars but have been turned off by their over priced gear sets. I've been really happy with SRT and EcoPower brands lately, both who offer gear sets for half the price of what Savox charges. If it were me, I'd buy the Eco Power WP120T servo.
