Hello ,
i made 1/5 tire adapters and 1/5 size motor mounts for inferno cars .
Here is a photo with the adapters installed on inferno mp9 ,compatible also with gt2 ,st ,neo etc.

Just note that these tires are aproximately 15mm larger diameter than the 1/8 gt tires , they are almost the same diameter with 1/8 buggy tires
For this reason you need to trim the body for the larger wheels.
