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.
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?
(newb apologies in advance; new to karting, but not to competitive motorsports at natl level)
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.
