sorry bit misleading
i run the j concept rulux b44 front and rear rims on my dex410, and run the same rulux rims on the dex210 but have got the b4 rulux front rims and used the b4 imperial bearing, and have machined the dex210 alu shaft down from 5mm to 4.5mm to make them fit
also make the car look nicer on the track than it already does as those rims look awesome
