i drove that car! it was at its challenge debut! it was SOOOO close to being perfect. i know that drive train VERY well now, and could probably get that thing into the deep 11s in about 3 hours. i have SOOO many questions!

Oh the want is there. The money isn't really an issue either. Space and time? Problems...

In reply to jmthunderbirdturbo:

Thanks for remembering the 2006 debut, the biggest issue that I felt that the car had was the solid axle (TR7) rear suspension. It had shortened trailing arms and stiff motorcycle coilovers and basically did not move, so traction was the biggest issue to improve. In the autocross, it would have been very competitive but the stiff rear would eventually lift a rear wheel in tight turns and the lack of LSD would just spin the wheels. The fix was to basically to cut off the rear of the frame and I welded in the mounting points for a complete 1987 RX7 Turbo II rear subframe. This involved a lot of other changes including moving the body back on the frame two inches, moving the engine/transmission back two inches, etc but all good things. All of this allowed me to get much bigger tires on the car (225/50/15 R6 Hoosiers). I really want to see how competitive the car will be once it is sorted as it has great potential!

How well does it do in the autocross with the rear update?

smiley The help is much appreciated! I got about half way through your list last night, hopefully going to get through the rest tonight, but it'll depend on what else I need to get done tonight of course.
