Yes, I've race-spec'd mine out of the box. It runs M05v2 single piece arms with droop adjusters (only fit on front though), negative camber top front links, TRF M-chassis shocks, turnbuckle rear top links, M03 alloy servo arm, turnbuckle steering rods, M05 front hubs instead of the M05ra ones, and a 3Racing M06 oil filled diff up front. Rear diff currently kit but will be upgraded to a TA03 ball diff soon. Alloy motor plate too. And a TL01 speed gear set. It goes quite well. Currently running 225mm wheelbase and an HPI BMW 2002 turbo body.
