I installed 3J Driveline last weekend. Comparable to a OSG for only $1050. Had a modify it a little bit to make it fit. The Quaife that I took out to replace needed no modifications but I was getting inside wheel spin still when exiting corners when I autocross. The 3J worked great ended up fastest time of the day Sunday. And 3rd in PAX. Only .007 from 2nd. Anyway here are some pics.
