4.0 is very safe for any motor.

I ran the Nosram Spec 2 for the first time last night with 17.5 and ran an FDR of 5.5 and I was quite pleased, quite quick and could hold my hand on the motor after each run.

Did anyone drill a hole in the shock caps? Or just left them alone.

I just added the rear upright to the lower arm and contected it the rear diff, when I pull up the lower arm it only goes up half way, I don't know if this is nomal for a Xray?

What toe and camber settings do you have right now?

Is the CVD shaft hitting the outdrive cup, or is it binding before that point?

When I built my T3'11 I noticed the camber link settings shown in the manual were a bit on the short side, giving me around 3.5 degrees of camber, and there was some binding, backing the camber off to 2.5 or so freed everything up happily.
