After my disappointment at not being able to donut at Dunsfold, Im now looking at getting a slippy diff. Ive read the whole internet today, a nd it seems like the Titan is regarded as "best" for a 7, but the Quaife appears a little marmite. I like the fit and forget idea of the Quaife vs the Titan servicing requirements. My car is predominately used on the road, I may do the odd track day, but I wouldnt want to compromise road manners for track use if that makes sense ? Id be interested to hear your thoughts on how you felt it improved the handling as well. Id like to have the choice of controlled oversteer at will in addition to the other benefits of a slipper.
