The first run of the converted F103GT was good. The car now handles better (as expected) and is more predictable. Traction is excellent (compared to stock) and steering is improved. The use and placement of a shorty LiPo allows for better tuning of steering. The car handles fairly neutral with a tendency to under steer when using a full size / height LiPo pack. I have not adjusted the pod spring placement, or toe for steering, or replaced tires, damper oil, diff setting, etc. I ran the car with the same settings from the previous build for comparison.

Things to consider for the build:
1) The wheelbase of the F1R is longer. It seems to be about 3.5mm longer than the F103GT. If your LMP body has pre-cut wheel wells - it will be off by bit. Purchasing a Response GT body would be a suggestion (+it's cheaper than the Courage bodyset).
2) The GT uses a TC bumper. I had to purchase the Response GT body from ABC Hobby (thanks MikeR for the tip). ResponseGT bumper
3) I had to remove the F103GT pod spacers and mount the pod directly to the F1R rear section. The spacers made the ride height too low - even with the highest setting for the axle blocks.
Current ride height w/o the pod spacers:
4) Body mount points are different from the F103GT. New body posts for the rear will be needed along with new placement.
5)Use the rear channel / groove in the chassis to route wire from ESC to transmitter. It makes for easier installing and removing batteries.
Initial setup notes:
+ Front black springs
+ TRF Rear damper with red spring. MuchMore #400 oil
+ Rear pre-load adjusted to allow rear pod to be level with main chassis
+ Rear pod springs @ suggested build height per Exotek instructions
Hope this helps.
