if you want to flex up the original r1 buy the new topdeck, dremel some material off it if you want more flex, and test with removing screws in the topdeck
the prospec has more flex due to thinner chassi and different carbon fibre
Ah, right, I now remember you doing that. The biggest flex improvement for the R1 is removing the 4 screws that go through the top deck and into the motor mount. It frees up the car a lot. If you still want more, you can remove the 4 "inner" screws on the ends of the top deck too.
