If you are looking at building and racing T-Jets competitively with your local group, you might want to be aware of the infamous T-Jet chassis number 4 (#4). This applies to the #4 open rivet chassis and NOT the #4 solid rivet chassis.
When Aurora Plastics created the mold for that particular chassis apparently the mold was created incorrectly which caused the chassis to be twisted.This twist in the chassis causes the front and rear axles to not be parallel. This resulted in all four tires not touching the track at the same time. As you know this causes a very bad handling car as compared to a car that all 4 tires are touching the track at the same time.
The twist in the chassis is so much that trying to boil and straighten the chassis is not worth it.

The picture below shows what was described above.
In order to have a stable and well handling car the chassis needs to be flat and square. Below is an example of a chassis that is flat and the axles are parallel. Notice that the drill blanks are touching the top of the tech block on all 4 corners.
