This is what I was leaning towards (BMW M3 by HPI ). Are the problems with HPI bodies the durability or aerodynamics?
I hear a lot about the Stratus 3.1 having a stable, neutral driving response.

I think durability is about the same. The problem is the aerodynamics or handling , any of those sport bodies are way sub par to any of the newer touring bodies.
Stratus 3.1
Parma Type-M
Mazda 6
Accord Euro-R
These bodies will way out perform the m3 and the more realisitic car type bodies from hpi. Youll find your car loosing control and not having as much grip and being harder to control all around.

Also, are the pillow balls supposed to be difficult to screw into the upper and lower A-Arm? I could only get them about halfway before it felt like applying more pressure would cause something to strip. I check the alignment and they appear to be going in straight. Thanks in advance for help and suggestions.

ASW - thanks for the advice. I am looking to race sportsman class so I will be going with one of the better performing bodies (Stratus 3.1 or Mazda6). I'll get some of the HPI shells to paint up and photograph.

Front end with shocks. Is roll bar correct?
OK. Finished the front end, and with the help/suggestions here, got the roll bar binding issue fixed. 
Suspension moves freely now. I have 5mm of pre-load on the front shock and 6mm on the rear. All suspension components, front and rear, move freely.

Have you adjusted your downstops/droop yet which is why your roll bar is on an angle. You've probably got about 8mm ride hight with the springs wound that far down. From memory the 5mm and 6mm is ride hight which is mesured with wheels on. You should have got a setup sheet with the kit it's a good place to start.

Good point. I should have put the wheels on. Slipped my mind. Will give it another shot, this evening. I see it's the little things with these cars. Going from off-road MTs to these guys are going to be an adjustment. The devil is in the details.

Gear Question
I raced mine in the Fireball Classic last weekend. I ended up second in the intermediat class but I stripped 2nd gear about 50 laps into it and that really put a damper on my race. I stripped 2nd gear twice. The first time I had the backlash to loose but the 2nd time I really thought it was set correctly. Is there anything special on setting the backlash for the gears?

Thanks
I'll give the remove the first gear and setting mesh with the second gear a shot. I was looking at the car trying to figure out a tool I could make so I could "push" the engine evenly on the chassi just to keep the gear mesh square.
PS I love the way this car handles. With a out of the box set up I matched my previous best lap time with the NTC3.

One-piece motor mounts
I have been reading about the second gear stripping problem and I wonder if a one piece motor mount would help. This should help keep the engine mounted more rigidly to the chassis as well as ensuring proper alignment. Any thought? I'm considering purchasing one along with my engine. Thanks.
=====================================
Just finished reading the MTX-4 section on www.nitrokb.com (Great site rmd), looks like I will be putting in an order for a one-piece engine mount
