1) I'm considering upgrading to GT-spec rear calipers and wondering if anyone has encountered clearance issues with dust shields, etc. after installing the vented rear rotors? Apparently, track cars were more concerned about cooling than keeping debris out, so dust shield were typically omitted. However, this is a road car, so I want to keep the rocks out. I've heard tell of a "Rally GT" brake system which presumably uses the dust shields, but don't know what any differences might be.
2) The GTs used a reinforced engine mount due to concerns about the increased power and stresses of racing. Although this isn't a track car, I'm running a 2.7L with modified "S" cams, so wondering if I shouldn't also add some strengthening to the stock engine mount. Are the strengthening gussets available as parts, or do these have to be fabricated for welding to the stock mount? Embedded is a pic of the mod I'm referring to. Does anyone know what they did for the 916s?
TIA,
