Re: Suspension gurus give me some guidance please!

Call one of the distributors to discuss, but, for example, I know the TCKline (Koni based) DA dampers will easily handle 400lb/in to 1,000lb/in springs, and likely more.

Re: Suspension gurus give me some guidance please!

That might be true for a non-adjustable damper, but for a quality adjustable damper, spring rates can vary quite a bit (2x, 3x?) and still be within adjustment range.

Re: Suspension gurus give me some guidance please!

The simple math;
assuming a 1:1 motion ratio up front (unlikely, but it's ballpark), and 3500lb car at 50/50 weight distro, you have 875lbs on each corner.
A 342lb spring will collapse 875/342=2.6"...

Re: Time for new pads, anything else I should try?

The Hawk 60s and 70s wear rotors much faster than the PFC08s, and don't last as long.
The ST47s have better initial bite than the PFC08s but are a bit harder to modulate on release.

Re: Rear trailing arm failure

The real advantage of the plate comes from providing much more material for the bung holes to weld to. But yea, prep chassis surface, fill in welds around bung holes, stitch plate edges to chassis...

Re: Rear trailing arm failure

Naa...I easily cut mine for an E36 with a hand held grinder. On an E36, if you don't remove the fuel tank you need to cut about an inch off the end.

Re: Rear trailing arm failure

RealOEM shows the E36 and E46 RTA 'cup' as the same part #.
If true, this means the bung locations are the same.
This means that just maybe, a E36 reinforcement plate could be easily modified...

Re: Brake fail at first HPDE

ATE 200 is usually fine for HPDE, but doesn't have a great wet boiling point. When's the last time you fully flushed brakes?

From your description, I don't have a clue as to pads or fluid.

I've always wondered about the usefulness of roll bars on a track car. Not meaning they aren't useful, but they are used for a different reason than a street car.

I'm tempted to unhook both ARBs,...

Heel/toe is a pretty advanced technique, and not necessary for novice. Of course, practicing is never a bad thing.

There's of course trade-offs for every decision. As an instructor, my default for a new student is always DSC fully ON. Then adjust from there, maybe.

Figure out your racing budget, and multiply by 4.

Wait, I'm assuming you'll be doing HPDE for a while first.
So for HPDE, listen to your instructors.

Re: First track day in the M3

Really depends on the tire you're running. Sticky tires with soft sidewalls like tons of camber, and you can eat an outer edge away in one session. But this doesn't sound like you're current setup....
