3.64 LSD, worth trading for 3.91 or 3.73?

[EricusMaximus]

Hey guys,

I recently picked up a mint 3.64 LSD locally. As this is going to primarily be a Track/AutoX car, I was looking for a 3.91 but the deal was too good to pass up.

What are your experiences with the 3.64?
Is this a good ratio for AutoX and Hillclimb racing while still being OK for occasional highway driving? The only past experiences I have are the 2.73 in my old 325e and the 4.10 open in a 318i.

Cheers!
Eric

I'd say that for AutoX or hill climbs a 3.73 or even a 4.10 (LSD) is gong to be the better choice for an M20B25 & Getrag 260. The 4.10 might be a bit annoying on the highway, but it will allow the car to perform better in the events.
