Well got it installed yesterday in my driveway. Easy as pie. Must say that FS won a life long customer with the service I have got from them the last two times I have done buisness with them. I placed an order for this mount at six at night, and got it in less than 24 hrs! That is amazing to me. And, when I called them up, they actually knew who I was! Try that with other bigger name companies such as FS. I will be getting my flywheel and quaife from these guys for sure! Yeah maybe I could find a slightly lower price on the quiafe, but the small amount of extra money is more than worth it to me with this type of service. Oh, and the motor mount is nice. Feels more stiff on stops, and accel. Just like I wanted. Sitll had a thump when I launched at 5K, but anything under that there is no thump at all. Just one question though. It was supposed to go with the cupped side facing the ground....right? Well, thanks FS...look forward to getting my JRSC so I can get my quaife and flywheel from you guys!
