Review of how it performed
As soon as I started the car I could tell it was alot.. well stiffer. It felt as if I had solid motor mounts... keep in mind I already have the 3 VF Engineering mounts on the car.
I pull out of the driveway and start up the road driving at a normal rate and when I would shift it definitly felt better, it felt as if there was NO give what so ever. After a couple of miles I decide to turn around and head back to the garage, I got into a little boost in first the shifted normally to second and it felt really good. I got to 30mph in second then decided to see just how good the stiffy worked... so I stomped the gas and hear this loud screeching sound... it was the front tires. The front end would usually shimmy alittle under that kind of load... but it didnt after installing the Stiffy.
I shifted into 3rd around 6k... and yes I was DEEP in big boost territory (19psi) and it was probaly the best feeling shifting I have experienced since getting the SVT.
I would most DEFINITLY reccommend the "STIFFY" to anyone thats looking to firm up there engine/tranny. The car feels as if all of the engine/tranny movement has gone. A worthy investment indeed!!
