Before you go buying a rotary stabilizer for big bucks, you may want to consider a rod type stabilizer such as Ohlin's offers. You will find few if any high end road racers who use a rotary stabilizer.
My Ohlin's go to guy is: Dan Kyle at Kyle Racing "kyleusa.com". If you are interested in the good stuff give Dan a jingle 831-394-1330, he's always willing to chat about all things racing from engines to suspension. Super knowledgeable fella.
