This is a set of 4 Mugen Seiki (E1024) "LD" White Buggy Rims.
These new wheels have a larger diameter (LD) than the standard Mugen rims.
The rims are 3mm larger in diameter, 1mm wider in width, and will work great with the new generation AKA and Pro-Line tyres.
With the increased diameter and width there will be less tyre flex providing increased corner speed and improved stability.
