Is Limited Slip Differential Option Required
#1

I've been looking for a new DE car and been wondering how many 968 DE drivers out don't have the LSD option.
Seems like there are more lower mileage original cars without LSD and I'm wondering if I should even consider buying a non LSD car.
I'm still a relatively new DE driver maybe only having done about 21 track days.
My previous car was an 1989 944 Turbo that I (ahem) rear-ended into a wall at Road America.
Seems like I could buy a nicer condition non LSD car and invest about $2-3K in a new suspension...or...buy a LSD car.

Thoughts ?

while LSD will make a difference, it isn't the end of the world, and there are very good aftermarket units out there for a LOT less than the OEM stuff - i am currently running a Guards torque biasing unit and LOVE it

And it may end up cheaper to get a non LSD car and put in a better aftermarket unit. The LSD units do wear out, so I wouldn't really give a equal 100k mile car with LSD more thought then one without.

I have used the Quaiffe LSD in a previous car and was very happy with it as well. If you buy a non LSD equipped 968 and it develops the dreaded whine from the differential bearing you can add LSD at the same time you repair the bearing whine. Good luck, Bob Blackwell.

I've driven my car at DE events both with and without an LSD and there is much fun to be had either way! From what I have read and discussed with Pete and others, a clutch-type LSD seems best for the track. Pete recently started offering a clutch-type LSD that is less expensive than the Guards - the Guards apparently being more durable than required for the power output of our cars. After this LSD was installed in my car last year in conjunction with some other transmission work, I noticed more traction out of lower speed corners, but it wasn't a night and day change. Although there is no question adding an LSD drop your laptimes, the non-LSD cars are still pretty good.

Thanks everyone for your comments - I really appreciate the support at this board.
I like the 968 alot but the 944 S2 is a great car too. Its been a tought decision process. Last Friday a friend looked at an 80k mile 1989 944 S2 with LSD - the car checked out nicely with a newer clutch/waterpump. But yesterday I spoke with the seller of a 60k mile 1994 968 without LSD and I hope to seal the deal this week. This car will be a once a week summer daily driver and used for DEs starting this summer so I'll be looking for to do a suspension upgrade as soon as I get the car home to IL.
