The lack of an LSD is a huge disadvantage for STX. It's been a while since I've looked at rules but without the LSD, would it be legal for ST?

There are guys (such as Terry Fair @ Vorshlag) prepping the new 412-hp Mustang GT for STX. They are 2 seconds behind the RX-8s (Houston Tour) at this point but I think when he figures out the right setup, they might be one of the dominating cars.

Please forgive my ignorance as my ZHP is a bit different from most, therefore I must pose this question to bcleaver and also the veterans here. Was a Limited Slip Differential an option for the ZHP or ZSP 330i from the factory? For your sake I sure hope it was as that I imagine would certainly give you a leg-up...

As far as I know, the LSD was never an option on a non-M3 3 series E46 BMW. I think that goes all the way back to 96 actually. It is standard of course on the M3.

The E30s were available with LSD and actually came standard in the 325is. It was an option in the earlier E36s (92-94, possibly 95).

Unfortunately, it was not an option.

[Mike V]

bcleaver probably already knows all this, but I just looked in the rule book and adding an LSD in STX is allowed. The car is legal for ST but is limited to a 225mm tire. That probably wouldn't work out too well. STX allows a 265mm tire.

bcleaver - do you plan to swap in an LSD eventually?

I'm looking forward to seeing how well it goes for you!

If the main focus is STX, I'm guessing the M3 rear (subframe, diff, etc) with its 3.62 final drive would be the best option.

[Terry]

Do you think that they would allow you to go to a higher gear set? I would be surprised if SCCA would allow this. Twould be great if they did, Eli.. That means you'd have to go enter your car in STX asap If they did allow gear sets to be changed I think you can still get a hold of some old rally gearsets... (ie, above 4.75...).
