Does anyone have any experience with AMS Stage 2 or Stage 3 tunes? I'm looking into a Stage 3 tune, but I would like to get some feedback from someone who has one.
You beat me to it.
Yes, the AWD Q50/Q60 V37/CV37 platform use an R190 Open Diff. As discussed, you can buy a helical LSD from Z1 Motorsports for $1598, as long as provide your core back to them. As for the front diff, the GT-R uses the same P/N as the Q50/Q60 AWD front diff.Yeah i dont have a awd but the awd models should also have the open diff in the rear. Not sure how the front works but likely not optimal.
Optimal enough to run a 11.0 on runflats. Not me, but a member from the VR FB community did that. Several others with times similar to that but with different street tires.
- Yeah i dont have a awd but the awd models should also have the open diff in the rear. Not sure how the front works but likely not optimal. I would assume the awd Q50-Q60's opperate off the VDC too thereby using the brakes to control wheelslip between the 4 wheels. GTR's don't use open diffs for comparison. Companies makes LSD's for awd cars and Z1 Motorsports points this out.
While great tires combined with the AWD provide an absolutely massive improvement, I still recommend the LSD for AWD Qs. Disclaimer: my LSD is still sitting in its box awaiting install. The LSD will provide benefits in 1) reducing the amount of break pressure being applied by VDC, 2) improves acceleration in high-speed cornering where wheel slip is common, and 3) provides major traction benefits in snow and heavy rain.If I had AWD, I would spend the $ elsewhere.
Those crackles and pops are excellent.
