Understeer on slow speed entry is the biggest thing I notice without the rear bar but it just makes sense on the faster style courses we get at Nationals. It is tempting to pick up that G37 bar for local events but I don't know if I want to introduce another variable to get used to when I travel.

Like any race car. you have to tune the suspension for the track. What works for one track may not be good for another.

Also where are you getting the oversteer and have you tried lowering your rear tire temp?

Turn in immediately after or in the transition from braking is less sharp than with a sway bar. Not something I'm particularly concerned about tuning out, as I feel the trade off is worth it while I'm getting used to the car. Lots of high speed transition grip and and good grip and rotation on throttle at corner exit.

You're not wrong, but test time is often limited. Not off the table as I develop the car and my driving. I just don't want to be one of those guys blaming the car when fundamental driving technique is lacking.

I know you are limited in time and testing. Best bet is trying to find something that work for most areas.

Okay, I think what you are experiencing is pretty normal or at least close to what I experienced as well. I found that I had to start my braking a little earlier and smoothly apply pressure when trail braking and to ease out of the braking as well. It takes a little getting use too but as you stated the gains are worth it.

I'll give it a shot. The car is very confidence inspiring and it feels like it is in a spot I can grow into. I'll still make small changes within the rule-set but I think it is at a good stopping point as far as suspension goes.

I've got wheels ordered and then my goal will be to get as much weight out of the car as I can. When that's all done we add power.

So, anyone having issues with ABS freaking out? Instead of going ice mode like most cars seem to do when you get on the brakes too aggressively, mine decides to throw ABS codes and warning lights and shuts it off, allowing the wheels to lock up. Then, as you the car starts rolling again off the brakes, the lights go out and ABS is active, again. The codes it throws is C1115 (Wheel speed sensor input fault) with is really generic and just tells me that the ABS module just doesn't see wheel speed signals it expects to see and shuts ABS off. I honestly think it's something in the software and there's nothing physically wrong with the car. I've inspected my speed sensors to make sure they weren't dirty or had a lot of metal attached to them, which they don't. I'm wondering if my Z1 diff cover has anything to do with it, but the sensors seem to have a good air gap from the reluctor wheels, and also I think I had the same issue while I had the stock cover on, as well, but I could be wrong.

I've had the same issue happen on my SP car a few times. For me, it always seemed related to heat. The only difference is mine doesn't immediately go back to normal. It generally takes 10-15 minutes of "cool down" time with the car off before the fault clears. Best part is that while the ABS is faulted the car won't turn off like it should because it doesn't know the car is stopped. Only way to get the car to shutoff is to push and hold the off/on/start button.

I had something similar on a wet track day that I'm still trying to figure out.
ABS was freaking out going into corners and all my dash lights lit up for a second or so.
They'd then turn off, and also set traction control back on (traction control went from turned off, to default).
I then turned TC back off coming out of the corner and the same happened twice more.
On the third corner, the whole car shut off and wouldn't start back up again.

I've been thinking it's battery or alternator related and haven't tested yet, but seeing this thread, I'm wondering if it could've been related to confusing the ABS.
