I would stick with companys like B&M, Ralco, TWM, or Mazda. B&M has been around forever, Ralco is inexpensive and decent quality, TWM has a mega reduction in throw but are usually very notchy, and the one I would recommend is Mazda. 20% reduction in throw is decent it will fit and feel like factory and be the highest in quality. Peter will probably know what ones work best for the car.
