Building repairing g35 drift car. Changed axles and coil overs, changed wheels and installed spacers, and changed leaky valve cover gaskets with kits from Amazon for a much cheaper price got the kits off Amazon but everything fits and works well no leaks on the new silver valve covers and the plenum gasket kit everything worked very well no leaks highly recommend and I’ll be doing the same kits here on a 350z very soon with motor mounts.
