Chassis is a loaded question as it is with any class. I would say in general, CRC is the least expensive and some would argue quality (I think pretty much all the 12th scales are well built). The Associated 12R5.2 is the newest and many are thinking the best. Xray X12 is right there with it, though parts availability on the Associated might be a little better (Nexus is in Marietta so that means Xray parts are close, plus Hot Shots is stocking some). Serpent, BMI, etc are all a little more exotic, which means parts sourcing is more difficult. Just starting out, I would look for a 12R5 (.1 or .2 if you want) or a CRC Gen XL. Used will set you back $100 to $150.

Motor is again preference, but the new Duo 3.5's are pretty amazing. Revtech and Reedy make good ones as well.

ESC, we mostly are Blinky now. Tekin RS or LRP SXX V2 (not the TC spec as it is too tall). Tekin means receiver pack, LRP is the easiest plug and play and my personal preference (beyond my BD). Just starting, feel free to use almost anything as long as it is no timing or you can turn off timing (the Novak GTB, etc can all work).

Batteries are 1s. Look for something 5000mah+. They are fairly inexpensive.

Servo, there are only a few options, but the Futaba 9650 is used $40-50 and available most anywhere and a good solid quick servo.

Tires it is also preference, but the common combos are (front/rear) black/gray, black/yellow, double pink/pink. Black/graylow also work but are only available in crc.

Come on down to Hot Shots Wednsday or Saturday and one of us can help you and answer questions.

At the moment the only track with a regular showing of 12th scale racers is TQ Racing in Chino Hills

Camarillo RoadRunners on occasion have a group also

If your willing to travel up the Golden State a bit north, NorCal Hobbies have a good group of 12th scale racers with a massive, smooth outdoor track.

Foam Tire Shore Ratings
Black - 40 shore: This is a low natural rubber compound. Special tire for insane traction carpet tracks. Does not get gummy like Purple. If you don't have insane traction you car will likely push with these.

Purple - 40 shore: This is a natural rubber compound. Popular front stock tire, carries good corner speed because it's firm. The foam this compound is made from gets more gummy late in a race. The more you run this compound the gummier and stickier it gets. A little more forgiving than some of the other fronts.

Lilac - 37 shore: This is a natural rubber compound. Great front tire for stock carpet or if dbl. pink is too much steering.

Double Pink - 35 shore: This is a natural rubber compound. This is the standard front tire for carpet in all classes. Its is used front and rear for 19T and Mod carpet and front and rear in all classes on asphalt.

Grey - 35 shore: This is a low natural rubber compound. It is just as hard as dbl. pink but it has FAR LESS traction. It is used to free up the rear of stock powered carpet cars for more efficiency and corner speed. This is the old standard rear carpet tire, most stock carpet racers use the softer yellow compound now for more forward grip.

Magenta - 32 shore: This is a natural rubber compound. Its softer than dbl pink so if you need more steering than dbl. pink use these up front. If you need more rear traction than dbl. pink use these in the rear.

Pink - 30 shore: Pink - 30 shore: This is a natural rubber compound. This tire is used in mod 1/12th on carpet and asphalt if the traction is low. If the traction is high it will lock in the rear of the car and make it push.

Orange - 30/35 shore: This is a rear tire with 2/3 yellow compound on the inside, 1/3 grey compound on the outside. This tire will free up the back of the car, also giving similar grip to yellow with added durability of a grey compound. Also known as Grey-Low

Yellow - 30 shore: This is a low natural rubber compound. It is the standard rear tire for Stock racing. It is used to free up the rear of stock powered carpet cars for more efficiency and corner speed.

White - 25 shore: This is a low natural rubber compound. It was the standard rear tire for 1/10th on road carpet racing. Its a little softer than yellow.
The main difference in the "Yellow" family and the "Pink" family of tires, is that the Yellow has a low rubber content and does not heat up as much and get gummy like the Pinks do.
If the track is greasy the Yellows are better, but the higher rubber content of the Pink family will generally have the most grip as long as they stay gum free.

________________________________________________
Boost=electronic timing advance, this is the most efficient way to drive a brushless motor, the timing is applied incrementally to keep peak performance from 0 rpm to max rev limit, the issue here is that a 17.5 motor for instance, is now as quick as a 13.5 motor for 1s, and more like a mild mod motor with 2s.

Timing= a mechanical adjustment to the endbell of a motor like in the brushed motors of days gone by. This method of timing advance will also increase performance to a point, but in doing so the motor will produce more heat, and reduce durability over time.

Blinky mode refers to no electronic timing advance.
Open esc = boosted, or modified.

When I started looking in to 12th scale, I found this post in the 12th scale forum. It helped me out a lot so I'm just passing it on.

I don't think you can put the AE front end on that one. The servo sits between the front bulkheads.

The whole LRP SXX Version 2 family can run 1s without a receiver pack.

The rear ride height adjustment is sweet. Still not ready to leave my snake though, as it is not the car holding me back, but my own driving.
