Im just saying if you come to the track day. You would be my first DFD
up. And we get to race R32s. Im in HPDE 1 btw. First track day.
Cool. Even though I haven't run NASA in a while, I imagine I could swing HPDE3. Still though, would be cool to
up. I need to get my shit together with the parts coming between today and the weekend and we'll see how things go.

So youre telling me the nearly solid mounts and bushings in my car would be harsh? What about H&R Race custom valved coilovers(with unknown specs)?
This car corners great from what I can tell. But its certainly stiff and I cant use all the potential yet.
Yes. In fact, I would keep a keen eye on that dogbone mount (the one that is under the car and bolts to the subframe) if this car sees anything other than a decently smooth track. I have gone through 7 of them including high dollar shit like VF. I have never and will never do a solid one as that would end badly at rallyx, it would probably end up ripping it right out of the subframe, which I have seen happen. That mount is the weakest part of the front of the car IMHO. I am currently using an OEM mount with BFI yellow bushings and ECS' red poly center bushing.
Some other things I would tell past me that might help:
- Pay attention to rear diff whine. If it starts to be consistent, change the fluid (diff, not Haldex) and see if there's metal on the magnetic drag plug. If there is any, start looking for a diff. Mine went at 125k miles and I threw an 87k used one off ebay in it. If it blows up and you aren't trailering, you can pull the Haldex fuse and drive home in 2WD mode just fine, minus the CEL
- HPP orange is the only way I've found that this car does not understeer at the limit. It's carrying almost 1k lbs of weight over each front corner and there's not a lot to do to overcome that. My car is set up pretty neutral with some slight off throttle/light braking oversteer because that HPP is still engaged on the brakes. When the tires are hot, it works
very well trail braking into corners, wel enough to make Big Brain Bradley giggle
- Speaking of brakes: I'm on stock calipers and rotors, I added stainless lines, the Tyrolsport stiffening kit, and better fluid and pads. The brakes are a very strong point of the car and surprise people. The pedal sometimes has some travel and I recommend a quick tap then apply the force you want. It should feel like you are putting your foot against a wall. Folks have tried replacing the master, slave, etc. and that "lag" is still there, even on big brake kits AFAIK with fresh fluid and fresh bleed. Maybe someone's resolved this as I have not looked in a couple years; I just learned to live with it.
- I am betting those coils are pretty similar to the H&R RSS setup, maybe with different spring rates? If so, that's a great track set up. It's not too low IIRC and has great balance. I have not driven an R on those coils, but everything I read about them is positive on track. They are stiff on the street. I've had 5-6 different suspension set ups, not counting the various spring combos I tried with the KW ClubSports. For autox, 700# front and 1100# rear was the ticket, but that's a different animal than track days.
- Tires. It will perform gloriously on 255 ultra super whatever the hot summer tire of the year is; just read reviews for ones that can handle heat - that weight over the front gets them hot. Rotate them often. I think I have Hankook RS4s on my track/fun set of 17x9s. For your first track day, I wouldn't recommend race rubber, as they need to get warm to work well and have a harsher cliff when they go off. Check with NASA as well, some orgs don't let beginner groups run race tires. If and when you do run race tires, I recommend 275s and a healthy stash of cash as you will like them on this car A LOT. It takes the point and shoot nature of the car and turns it up a couple of notches. AWD, that much sticky rubber (and for me, the diff and HPP) can power through a lot of things.
It also looks sexy as hell
