      I was told that not all DD2 chassis OEM’s support an extended ‘porch’.  I prefer an OEM engineered solution vs a modification.  Why?  So that the chassis may be returned to its original configuration.  DD2 appeals to me given the leveled nature of Rotax Max DD2.

      So questions:

      1) which chassis OEM’s (i was told CRG & Birel) support an extended porch as engineered from the factory?

      2) does the porch extend the overall length of the kart?  if yes, is there a Rotax Max DD2 overall length rule or are my feet simply closer to the front?

      3) i am 6’1″ – i am assuming i will need a porch extension.  i know rental karts really jam me up.  is 6’1″ definitely requires a porch?

      4) i cannot realistically get my weight below 190.  does my weight factor into my chassis purchase decision?

      1.)  CRG, Birel and OTK all make an extended porch.   The CRG kit will fit on Parolin/Merlin, I know that for sure.  Also remember CRG, Birel and OTK make a lot of different brands.  I can send photos if need be.

      2.)  Yes, the overall length will increase roughly 4 inches.

      3.)  Height is one thing, but it’s really the inseam.  If you are looking to purchase a chassis, try to seat in one first.

      4.) Most chassis now some to be either 30mm or 30mm/32mm combination.
