I scrolled back a few pages, noticed a note about a newbie driver. If you can try the sway bar during a test day, absolutely give it a shot. Even better if you can get the same driver to test it with and without. We had a car that was slight-understeer and wasn't tail happy in transitions, so it was on the safer side. At least one of our drivers was a couple/few seconds a lap slower, and he had an off from time to time, so that's who I think the car needs to be setup for.I forgot to add, the 940 donor sedan for the axle had a sway bar, going to give that a try. We have always run without one since we got the car.
I would also expect the G80 to work better without the rear bar.
Also, the recap on the race where the studs broke off the turbo and the wastegate housing was held on by only the downpipe...that sort of race sounded VERY familiar. Lots of stuff goes wrong, but it's still a fun weekend. Ours broke the downpipe at the turbo once, got louder, and louder, and LOUDER..OK, I'll pit now. We also had the WG actuator loosen up. Another time I think a motor mount broke and we punctured the oil filter. Part of the fun for me was trying to anticipate and prepare for failures.
