MB Slot make a fibreglass chassis for it which takes a SlotIt pod which gives these a huge performance gain

...my MB/Allslot with NSR Shark 30 in a SlotIt IL pod is one of the quickest cars round our track, comfortably ahead of the NSR F1's.

To be fair we classify non plastic chassis cars as Open Class so not really a fair comparison with the NSR's
