looking to upgrade from tlok. looking at the torsen t2r but have read mixed reviews but the bad was from many years ago have their problems been remedied. and I was looking at the auburn autocross road race series seems like it might be really good. and then the tru trac heard a lot of good for them. this is going in a fox with coilovers a maximum motorsports panhard. a torque arm will be installed shortly. I have really gotten into the autocross and will probably do some other track events this year also. any info would be appreciated, I only want to change once if possible.
