I have heard that it is not legal to race with a full air ride suspension. Is this really true? Are there any NHRA rules against it? I have seen a couple drag cars with air bags on the front but they had coil-overs on the rear. Would there be any disadvantages to running a full air ride? Air Ride sells a four link setup that I was looking at: http://airride.com/productinfo/air4link_parallel.asp just wondering if this is legit. I wouldn't want to do anything that would keep the beast off the track. Thanks.
