What about the LWFW? Short shifter ok?
LOVE my LWFW from Kevin at UWM. OMG what an improvement! Colin @ Cantrell Motorsports did all of the installation. Just excellent at improving the feel on the car.

Don't need a short shift. Really better to focus on smoothness at the track anyway...

While the motor is out, probably good to get steel synchro's forom Porsche Motorsport while refreshing the transmission, though... That will pay bigger dividends, in my view...

Check with Kevin at UMW for his ZC turbos, though.... instant boost which will really help you in exitting corners.

Might as well to the GT3RS crank and Arrow rods or Carillo's while you're at it. Also from UMW!

As you well know, the TT's have Titanium connecting rods as it is.... s they really don;t bend or streach or break.... it's generally the HARDWARE (bolts) that can be the issue here, so for the less expensive routem you could always consider upgrading the rod-bolts and etc...

I'm sure there are some VERY experienced guys who can weigh on on this.

Yes, the GT3 does, but the turbo does not. Or am I losing my marbles?

True the hardware is a problem but the rods also have a tendency to bend ........I believe CJV has some pictures of that cause it happened to him.If you are gonna spend the time and money to get to the rods it would be foolish not to change them IMHO.

BTW Tom sorry to hear and glad to see the TT is on the road to recovery.

Wait....dont tell me that....your running ....BONE STOCK!?!?!?!?!?!? Other than suspension? I bet after you get a couple k miles on it, you'll go ahead and get a flash, which is really all you need with that car, maybe an exaust, like you have before, there are ways to combat this without going too overprotective.

I guess your challenge now will be, achieving the same laps times with less power, can you do it????

Chuck,
How did your rods bend?

gas?
on track or street?

respectfully trying to learn.

I knew it would only be a matter of time. Once you drive about two laps or so you will be feening for that power again.
