Ok I have an lsx swap in my s13. The stock rack went out shortly after I started racing it and while racing it felt like it had too much assist. I was good beforehand so I figured it was over flowing the rack. I made a restrictor (%50 smaller) and put it inline on the pumps high presure side. Then I got a new rack, went racing, and the same thing happened again. I was wondering is anybody else had this iproblem or knows the fix?
I'm changing racks, on racks, on racks!

 

Try one of these, they've been field tested...
