    Found the first thing I Dislike about the car: no easy way to install tow hooks. Requires a couple hours of labor.
    Front kinda require bumper / splitter removal. Rear requires backup light removal.

    Billy sure isn't perfect !! Explain yourself !!

    It kind of weird. It's got to be an optical illusion, or possibly a result of the tricked out IRS; but the rear wheels almost look like they have no negative camber.

    Please be sure to take out the front spring shipping blocks and rear shock blocks before driving it. I'm tracking an R right now and it still has the blocks installed.

    ....and another R had the rear blocks in here at Sonoma. FTLOG check them...


    Emilio - being a wheel expert, what do you make of the much thinner lugnuts used on the 6GR wheels? The taper has about half the surface area as a stock nut, and that's a lot more load (150ft-lbs) on a smaller mating surface area.

    Also, the 6GR lugnuts are smaller in diameter which means there's less material between the thread and the outer part of the nut. Is this a concern to you? I just saw 6GR wheels today and I'm not so confident on shrinking down the thickness and mating area taper on a 150lb torque spec nut.

    Seems okay to me. We torqued mine to 150 and just drove for about an hour at streets. Wheels didn't fall off so I guess it's okay.

    100F weather at Street of Willow CW today. 1:26.2 on stock PSS. And 1:24.07 on RS4 and passenger. Same driver
    Stock PSS would fall off after 1 lap. RS4 falls off after 3 laps.

    May be shipping blocks are still on the car. Need to look.

    Found a 2nd issue: no grab handle in passenger seat !! I was scared ****less in passenger seat and nothing to grab on

    I question long term durability of that small lugnut.

    What hot pressures did you run on both tires?

    I'm running the 6GR wheels. I have the longer ARP wheels studs and these Dorman open face lug nuts. They have a much larger mounting surface than the thin tuner ones from 6GR although not quite as large as OEM. The only drawback is you have to find a fairly thin-walled socket. I'm looking forward to some 6ULs in our sizes though.

    We both tried around 35-37 hot.

    Weather was warm with high track temp. So every session (we both showed up in the afternoon) had to bled down. Also ran sessions with AC !!

    Sounds like RS4 are the same compound as RS3, but just a more aggressive tread pattern, but still horrible when cold, soft sidewall, tons of road noise, and poor on the wet, but hold up to really high loads and temps like the RS3, which isn't in the same class as the far more street able PSS.

    I like the PSS & PSC2 at 34-36psi hot. They're crap and greasy above 38psi.

    Billy is king at BRP !!

    But compare 2 lap times with Supermiata time (Sonoma and SOW) My guess is 1:57 on stock PSS. 1:55 on RS4/71R/Rival. In winter. Add couple of second for summer. This is with my weak ass driving. Billy will own it

    Btw. I was a bit uncomfortable with T1 at Sonoma and Chicane at SOW CW. Left easily 1/2 second there. Car feels unsettled. I can describe what I needed, hopefully Billy knows what I am talking about. I need to re-learn those corners.

    I'd guess around 1:50 in the R (what I did in a MP4-12C on non Corsa P-Zeros) if not better and 4 -5 seconds off that in the 350 on PSS.

    You really need to be around 34-36psi hot on the PSS. What mode and shock settings do you run? There's a company making a Z28 style adjustable gurney flap for the 350TP spoiler. I'd get that as a tuning tool.

    Stock GT350 in good weather, I think 1:56 or so. With the RS4 on 1/2" wider wheels I ran, maybe 1:54. Not sure how much faster the R is on a typical two minute course (not a roval).

    We both saw around 295 oil temps but they stopped there and never climbed any higher. That is with the original oil. I suspect that will drop a few degrees once I switch over to Amsoil and add some nanopro. I had planned to drop it off at the dealer Monday to get the oil changed but William told me about streets Friday night so I figured one more track day.
    If the oil temps are still 295 after everything I might investigate swapping the OEM exchanger for a slightly larger Setrab. But I don't think I will need to. Temps for everything else seemed okay. My experience is slow tight tracks tend do tax any cooling system more than tracks with long straights and higher average speeds. It's all about the CFM of that air mass.

    I was not uncomfortable through the chicane, just careful as it's basically catching air as it comes over the brow. Kind of spooky when you have a few milliseconds to get the car rotated slightly when it lands for that kink without chucking it off into the desert. As I had intended to drive it home I naturally tapped the brakes there as I landed to scrub enough speed to make the kink.
    Really impressed with the magnetic shocks through all of the lumpy low-speed corner exits at Streets. It just hooks up and drives off them like a rally car.

    Billy you have mentioned probably four times in this thread about running a specific air pressure. No offense but I like to also use it Tire pyrometer to see what the tires are doing. That's what I used to set pressures, not solely aiming for a specific Target and ignoring pyro data.
    That said, on a hot day on the two tracks we ran on the PSS do end up being happiest in the mid-30s. I think the RS4, being slightly larger wanted a bit less than that. I arrived right before the last two sessions and it was Africa hot so I wasn't being too fussy about it just bleeding down to get them close. Mostly we were just goofing around.

    I select track mode and turn off advanced trac.
