If you plan on going Turbo the JWT's would be the best to use,
NISMO still sells these mounts.
I havethe JWT's and around the first year the mounts and vibration are unforgiving (The car feels very solid specially when you shift, love it) also amplifies the lope/feel of the JWT cams in the cabin

, it eventually becomes livable. imo
Place Racing just revised there mounts and look to be very well made. now there mixture is injected into there own mount casings. The old design had the poly sliding out of the casings.
