is the .2 that much better than the .1?

12mm vs 13mm shocks. Look on associateds website to get the full update list. The .2 has minor upgrades and adjustments to the .1

Not sure how much better the .2 is from the .1. the .2 came out back in October I think so it's still new.

I watch these reviews alot by RazorRC he races on carpet tho. Here is his .1 and .2 reviews for carpet.

I have the B74.1D myself. I can't tell you how it is compared to the .2D or anything else since I only ran it at the track once with electronics from my basher. Next time I can go down to the track is in March due to my schedule. With the B74.1D build, it went ok. it was my first kit and 4wd car so I ran into some problems but I fixed them. Had my uncle solder up my motor wires which btw I am using a Hobbywing XR10 Pro 160A with a Hobbywing V10 G4 13.5 motor. As Razor RC mentioned the B74.1 is a little heavier than other cars so since I am doing stock 13.5 I am planning to get ceramic bearings.

Some other stuff I am running in my .1 is:
Xpert 4000 series servo
Radiolink rx/tx (budget radio from my bashers, planning on Futaba 4pm or Sanwa M17 down the road)
ProTek alum motor fan
Jconcepts Ellipse Silvers both front and rear
Here is my .1D with my electronics from my rustler.

Here is a guy that races at my local indoor clay track.
