I've had the Team NTC3 kit for 3 years now. The only thing that regularly breaks on it is the front suspension mount. (only after I hit things) After breaking a couple of shock mounts and diff covers I bought "The Fix" which ties the top shock mount to the chassis. I got it off of e-bay.
We run on a smooth asphalt track and I set it up with red springs all around. It's not the fastest car as the Mugens out run me frequently but it did run well and has given me good stress relief over the years.
For what it's worth.
Worse day racing is still better than your best day at work.
