The Cusco quality is off the charts. ABS works fine with it and Cusco recommends its own LSD oil but not strictly, but it states it clearly in the warranty that if you use the wrong oil, there will be limited warranty.

No offense mate, comparing Cusco to OBX is like comparing the Nissan GTR to Geely.

Cusco has unprecendented wins in World Time attack and circuit racing including GT500. I personally have sold over 20 LSDs over the last year in Japan and the rest of Asia and had nothing but wins and never ending compliments.

Cusco develops its LSDs with type MZ for race and RS for street with no noise.

OBX is both noisly and rough and is made in China. We have removed a lot of them in the lower hp cars like Hondas here in WA. Hondas have high power to weight which we use for racing here in WA, and we won't even use OBX in these cars.

Attached are some OBX reviews: My OBX lsd Review/short and sweet///pictures added - Honda-Tech

What you pay is what you get. And bear in mind, labor is not cheap here in WA. Put in a cheap LSD and have it fail and with OBX's history of cracking, better hope that the pieces don't damage the diff or gear box. At the end of the day, you will be up for more money than buying a high quality Cusco LSD installed in the first place, and possibly a new diff or gearbox.

Feel free to drop by, we are currently removing a cheapy OBX LSD that failed and replacing it with a Cusco LSD on a FF Honda EG civic with a H22 transplant.
