Lot of things going on, but I finished the project finally.

To make sure everything cleared when I lowered the car, I sanded/cut the bottom of the interior. It's not that glaring when it's all put together so I did not bother with making new pans.

I am glad I did this mod to the bars. I did not like how the bars and driver looked before. I cut and sanded the bars so they would fit cleanly inside the body and glued them in place.
Once this was completed I glued the driver figure back into the interior. I adjusted him to where I thought it looks best and let the hot glue flow.

That photo will also show you the lowering accomplished. Again, to do so will take some work and not sure if it's something you will want to do...but I had fun grinding :)

The rear of the chassis is where I sanded. I just used a flat file and reduced these areas slightly. You do not need a lot to get a better stance.

I removed the big pipes using a milling bit in my Dremel. Messy, but necessary. You will likely lose the "T" shaed mounts but the pipe can still be glued back on with the leftover material.

You need to remove more of the material on the sides to allow the body to sit lower. You simply have to sand until you get the look you are after.

Now you can see the interior back in place and also the lights. I soldered and shrink tubed the old wires together after removing the RF capacitor. Then each light board was installed and hot glued in place. I mounted them in the body and bypassed the original mounts obviously. I did this as it just makes it easier for me to remove the body and work on the car if needed. The wires curl nicely and form into the hood, out of the way.

All finished. I think it turned out ok.

And it runs wondefully. Lap times tell me I am right with some TA models in our series. In fact it was neck and neck with my fastest Scalextric Mustang with 3.7 second lap times.
Overall a fun project and happy with the results. Considering my goal was to keep as much stock as possible, the performance is pleasing.
