they could make these for the cross member. it replaces the rubber isolators on the cross member and helps a TON when getting rid of wheel hop for the b15 guys. id assume they would work for the b14/b13 as well. i have them on my car and they work great!:
"These were getting popular an msv so i made a whole bunch just before it went down.
These UHMW washers replace the crappy "floating" style factory rubber bushings on the motor mount crossmember thus tightening up the connection between the motor mounts and the chassis, reducing wheel hop.
I use these and es mmi's and wheel hop is all but gone!"
a guy makes them for 7.50 shipped for the b15 but im not sure on size for the b14/b13...
