I have just the one for you it's a push race gas set up I had it on a 2010 m8 hcr figure it runs about 285 @ 12lbs. I never ran it 7lbs. and it went every where I wanted to go i paid $6700 about 2 months ago and 140 miles it seemed pretty bulletproof to me enough so that I'm getting one fit for my 2012 any questions call me 701-240-7990 or email me at floorcon@gmail.com thanks shane
