I think the stock type R strut bar is good for the money, unless you want to go crazy and get spoon or mugen or some of that craziness. Also, don't get a carbon-fiber one. Carbon fiber is very rigid and strong when you pull it, but when you push it (which is what happens with strut bars, they push in), the carbon fiber can bend relatively easily. Go for a steel or aluminum one if you really want the best product. Carbon Fiber is just really a gimmick because everyone drools over it since it's used all over Le Mans and F1 and all that craziness. Well, good luck.
