2Bartuning Track Car - One off and only done 1450 Miles

Recommended Posts

Here is a chance to own a fully chassis rebuilt and track prepared Supra.

 

Built in 2009/2010 by Autotec2004 and 2Bartuning (Ryan.g).

 

The concept of this car was to make the Supra as light as possible in track based trim and completely balanced. To achieve this most of the original chassis was removed and rebuilt using lighter T45 (aircraft grade) chromoly tubing. Whilst rebuilding the chassis we decided that the engine could be moved back 15inches, which would make the supra as close as possible to being 50/50 weight distribution.

 

The whole build was documented and posted below to see the level of care, safety and workmanship which was involved.

I could talk for days about this car but its best to grab a seat and read the whole of the project.
