If their results are accurate, their gurney flap isn't helping, at least at a couple of their data points. Adding AoA is more efficient than adding the gurney.

Re: Camber Plate Recommendations

Both of them will convince you that theirs has more bump travel than the other. I will say, GC talked to me on the phone for 30 minutes, and sent emails and pictures of their test fit-up rig. This...

Call GC, ask them why their plates are better than Vorslag's.

Re: Tracking with 996 Brembo setup

Noise, and if you get fancy ones (titanium or such), they may reduce heat transfer to the pad.

No shims. Cause, not needed on track car. They have nothing to do with helping with even pressure on the back of the pad. The real PIA with shims is when installing new pads; the shims make them...

Re: E46 rear subframe attach point cracks.

Yea, we were figuring a day the traditional way. Was hoping for a dirty 3 hour fix with a sawzall from the top approach. :)

Re: 95 E36 M3 brake duct sensors

BINGO!!

So, the ETM for the 95MY doesn't seem to have it listed anywhere. But I've got one for the 98MY, and it has:
"S198, Thermal switch, heated jets"

I'm betting that's exactly it.

Thanks. I'll double check the ETM with that in mind.

Re: 95 E36 M3 brake duct sensors

That right side one has me puzzled. Can't find it in Bentley's or the ETM. And I don't have heated washer nozzles, door lock heaters, or such. Odd.

Re: Welding RTAB Pockets: Wire and Gas Tips

Ahhhhh gotcha.
Then 0.03" or maybe 0.025 wire. I've used 0.03 quite a bit when I weld ~3/16" plates to ~20 gauge body sheet stuff, no issues. 0.025 might be a little more resistant to burn through....

Re: Welding RTAB Pockets: Wire and Gas Tips

PS, if your using 110v as input to the welder, that'd be a reason to avoid the 0.035 wire. At least my Hobart runs much better using 0.03 than 0.035 when I have to be on 110v.

Re: Welding RTAB Pockets: Wire and Gas Tips

It's MIG and mild steel, so there's nothing special going on. I think I used 0.03 wire and I'm certain I used 75/25 gas. 0.025 wire would be too thin. 0.035 would probably work fine.

Re: Wheel Stud Life Span?

I doubt there's a simple answer to that. The thickness of the wheel will change with temperature, along with the length of the stud.

Re: Wheel Stud Life Span?

The standard 'reduce by 15% if lubricated' applies.
BMW spec (E36) is 90-110Nm dry, so taking the middle ground, that means:

Dry: 100nM, 74 ftlb
Wet: 85nM, 63 ftlb

Re: Wheel Stud Life Span?

Well, I can't find prices on their web site, so yea, that's not a great sign. :)

I doubt any 12mm stud would last a 'lifetime' of hard track use.

Re: Wheel Stud Life Span?

The MSI source is good intel.

I replace front wheel bearings once a year (at least the left one anyway), so it'd be a PIA to refit to 14mm everytime.

Re: Wheel Stud Life Span?

Interesting. I've found that a torque stick is pretty inconsistent. Ie, use torque stick, then torque wrench, and there's a few that are always way off, sometimes over.

Good point on the rears....
