I have the trans out of the car and will be putting a Quaife in or rebuilding the LSD. This is a track only car.

I know I will give up some on braking with the Quaife but other than that I'm not sure of which route to take. The Quaife will not require adjusting the plates nor will it have plates wearing out. If a rear wheels is off the ground I gather that the Quaife will free wheel. However, with 900/1000 lb. springs if I have a wheel off the ground I may well have other serious problems. The LSD on the other hand can be set to different slip levels and seems to work better under braking.

It's not a monster car, just 375 rwhp turning 303.30.18's all the way around.

Thoughts?

I plan a Guard LSD eventually in mine, it's cheaper than a Quaife and also gear-type. Mine's a street/track weekend car, so I don't want to have to rebuild a clutch-type LSD every 30k miles, I want to install the LSD and not have to do any special maintenance on it.

For your track-only car though, I'd say go with a clutch-type, you can tune it using clutch plates and springs to exactly the torque split you need, and if only used for track weekends, you won't need to rebuild for a bit. On the track, that LSD effect under braking helps quite a bit.

I'd opt for clutch plate as well.

Go to the POC website. One of thier old Velocity Magazines has an article on limited slips and goes over in detail their operation and track impact. It also covers Quaife type and clutch plate types.

Very insightful.

contact Paul Guard at Guard Transmission 888-89 GEARS he sent me some very good info on the differences between the two if I can find it I will post it.

When I spoke to Paul Guard and he said that the LSD is superior to the Torsen.

what's the difference between them and a lsd
wouldn't that be better
how does lsd alter braking
