Tow truck was for fusing my clutch to the flywheel. I was racing an Underground Racing Gallardo so my only hope was to absolutely murder him out of the hole. I managed to do it, but I launched so hard that I killed the clutch. I was so happy that by the top of 2nd I was pulling away from this Gallardo, until I tried to grab 3rd and couldn't do it. I was running an experimental South Bend stage 5 ferramic that I was guaranteed would slip properly and take the abuse without fusing to the flywheel. Needless to say I proved that wrong. I had to tow the car over 100 miles home and have it replaced. South Bend warrantied it and provided a new, less aggressive design which started slipping like crazy and not holding any power after 10k miles. They refused to stand behind the product and blamed me for their product failure. I was out of pocket for a $300 tow bill, labor costs, and eventually paying for a new clutch after these failures.

I hear that their clutches for this platform are much better now, but I'll never put another South Bend product in my car. Spec has been great so far.

I went to the 1/8 mile last week and got a couple runs in, but they were so bad I won't even post them. Strip was the busiest I've ever seen it, so sitting in lines killed my IAT's - they were 160+F each run, so power was way down. Launching, the auto went to 3rd on it's own, instead of 2nd, due to wheelspin, which killed ET.

Mods are in sig, FBO minus inlets. I have GC lite turbos and TBI going in this week. once I get it tuned again, and have practiced my launch technique more, will get some real times.

Launching in 2nd seems lole the way to go.

Without an LSD or slicks, most FBO cars probably make too much torque to do any good with first gear. Plus it is one less shift to make.

Hey all, picking up an e60 soon. So AT is better than the manual in term of durability?

Looking to get as close to the 11's as possible.

Where are the heavy hitting e60's at?

What LSD are e60 guys running? It seems like the only option is Quaife.

Quaife is NOT the only option, there are plenty.
MFactory Helical
TurnerMotorsports offers clutch/Salisbury 1/1.5/2 way diffs
There's swapping in an M5 diff too.
Quaife
Also think diffsonline has some options, haven't checked them out though.

I am planning to pick up an MFactory helical LSD in the next week or two.

Only issue you may run into with the 5 is not many places are going to have the 3.46 diff cores available, so you have to send yours in or order the lsd only and install it yourself, or take it somewhere local.

Thanks for the information. I'd probably have to ship mine to have it installed.
