Willis' FA5 M90/JRSC Build

[WillisFA5]

From a performance aspect, all setups should have stiffer-than-stock motor mounts. This allows the engine to move less (or not at all), which results in less wheel-hop and, typically, better traction.

That and even with my 'stiffy' my header is hitting the underside of my car on hard shifts. I can avoid it mostly, but it will end badly if you add more power into the mix.
