First my engine mounts have arrived, going to try and swap them in tonight. 
Second....Iíve been looking at the nto1ís, since I have 10Ē rims, Iím going to go with 275/35/18 in the front and 305/35/18 in the rear.  The rear is a bit tall but it shouldnít be an issue.  Or do you think I can fit the 315/30ís on my 18x10Ē rim?   They will fit in the width because I have wider rear quarters.

You'd want an 18x11 for the 315. It's pretty darn wide for a stock body. Wish the NT01 came in a 295/30-18.

R888 comes in a 295/30. Decent alternative I suppose.

Update..... put the new mounts in and my hood wonít close.... ronin mounts.  So Iím going to shave them down a bit first.  Next, is there a good that gives more space? Scoot? Or put in aluminum mounts that are cut perfectly to get the right height?

Slam it and it will self clearance. :)

You could also make some custom urethane biscuits instead of aluminum. Seems easier than a new hood.

Should be able to tighten them down harder to compress the rubber. If that isnít working you can trim them down.

Youíre unhappy with vibration already definitely don't go with aluminum.

Took the belt sander to the mounts.  Itís a tight fit.  I have about 1/8 between the rack and oil pan, and 3mm from hood to intake.  Gotta keep the mount bolts super tight, not much space for movement unless I lower rack spacers more and drop the engine more, but I donít wanna do that.

If you are running the factory p/s rack you could potentially "roll" the rack forward in its mounts to provide a little more clearance on the hard line bungs... or grind down the bungs a little if that is an interference point.

Nope.  Running an atomic Rex Manual rack.  Itís smaller then stock.

The mounts shrink with heat cycles over time, place in oven for a bit and install hot. should help.
