The plan for the car does not include an M96 for much longer
JRZ remote rebound adjusters are pretty affordable, $60 ea.... BUT, they are built in Europe
Oooooo, saucy. Can’t wait for the engine update!
I’ve probably lost 10 rebound adjusters across all my race cars….8mm deep socket works just fine . I keep one mothballed for the rare occasion of a crazy long day that has brain fog setting in and I don’t want to risk getting +/- mixed up.
I had a really fun time at the track today - I made adjustments each session, 1st session out was a couple tenths faster than last track day, next session knocked 6 tenths off that and then I made a stupid mistake and made 2 adjustments as once and one was a dumb one. I was thinking after the 2nd session, car was faster and I felt like it had more in it, the pace was coming more easily. Now, I am way off on pressures where I ran last year, I thought maybe I was making up for some handling woes with the low pressures and as I got the car a little better sorted, I could creep them up - Nope. Went out and the change from 33F/33R to what ended up 36/36 was brutal. So, the results of the suspension change I made are moot and I will need to re-run to see. All the changes I made are documented, it was easy enough to get down what I needed between sessions I didn't feel rushed so I think the spreadsheet will work out OK. Regardless, I feel good, had a ton of fun, the car ran **** and sounded awesome, **** mufflers. I'll review data tomorrow and video in a couple days.
Couple take aways on the machine - I'm excited to see what the braking data looks like, I made it a point to really try to push the big braking zones and those stupid big brakes feel like they really may be a noticeable improvement, we'll see. Also, part of the adjustments today were to stiffen the front in an effort to get more weight transferred to the rear on corner entry, much elevated ice mode in a specific turn followed this change, I don't think I fully prepared to link the 2 things together at this point but I'm leaning that way. Ice mode was not enjoyable to drive through or try to drive around.
Thanks to all the guys pushing me along and those offering experience and advice, I really appreciate the help on all fronts. Got to thank Angelo (Anze) too, we did run downs after the first 2 sessions and he gave great, smart support.
Fastest not so fast lap vid is up... I've gone over the data a bit and man... confusing kinda. Theoretical best, which is taken from best sector times puts my best of the day in the 3rd session, when my fastest lap of the session was way off pace. The car felt kinda fast in the session but I could see at the time, it was not being reflected in lap times. So, while I thought, and think the pressure rise was not great, it is a little conflicting depending on how you look at it. One thing with the data and a public track day in a car that's a little fast, traffic skews and doesn't highlight itself in the data. So, I have found the theoretical helpful but haven't had such a wide range between session best - 1:21.5 and theoretical best 1:18.7 in a long time. Some of the other data looked pretty good from that session as well, I think I need to drill down deeper.
Anyway, maybe I'll geek out and share some screen shots of data I'm looking at if you guys have any interest, let me know.
Hope you enjoy the ride along for a slow, fast lap - a 1:20.2 compared to a PB here of 1:19.3 and a goal for this year of... a lot faster..
Jason, just thinking out loud. Don't know of you have your old front bumper and wing, but have you thought about putting them back on the car and dialing in the mechanical grip with the JRzs, to see what you have. You got very big tires, alot of aero and new suspension. Alot to dial in. Then work on the new aero.
Good question Glenn ! NO ! No going backwards. Despite the fact the my fastest time has not caught up, my times are generally faster. I only got into consistent 21's and 20's towards this time last year with a lot more seat time under me, I am there constantly this year. I have a plan and despite the fact things have not gone exactly to it, I'm not far enough off to abandon it yet.
Definitely get what your saying. Not suggesting abandoning it at all. Just dialing in the mechanical grip with the rubber and JRZs first. Then add in the aero and adjust the suspension as needed.
You got alot of moving parts, but no doubt in my mind that you will get it configured.
Great video. It reminds me of a few times I’ve been on the track yo-yo-ing with another car for 15 minutes or so. Times and speed didn’t matter as much as the fun!
Probably why I like riding through the woods on single trac with similar skilled/fitness riders. It’s much cheaper but not sure how safer it is.
It was fun... Running with an actual fast Mustang. Literally the first time I have ever had that happen, and it wasn't even that I was particularly slow, he was fast. Most of the times at these days, the big HP or expensive cars you would think are fast... aren't. They are, but the people driving them aren't. It's the older cars that are really shredding, E36 and 46, Turbo Miata's, even some FWD stuff - GTI's and Mini's off the top of my head. But occasionally, a ZL1 or Corvette, or in this sole instance, a GT500 (I think) with someone that can **** is behind the wheel and they show you, some of the big HP American stuff is not to be taken lightly.
Video was good, pretty smooth work there and that track is nice looking... all our tracks are flat.
That track is actually bonkers. It takes a ton of car control to keep it out of the weeds and the fences. Its tight and twisty and takes a big set to push the limits.
Maybe next year ill get him down to njmp where u can take some chances with low consenquenses.
It does look like @zbomb is gaining his confidence back. I expect a new pb next trip.
That lap looks like it was a lot of work especially through the oval bowl! Front bounciness seems to have been lessened, it's still there but less intense.

Better... But as you see, still work on setup and driver.
Here's how that section through the bowl looks in data. Fields from top to bottom are : throttle position, steering angle and lateral G. You can see, hit the highest lat g of the lap and attempt to get back on throttle and immediately go into steering correction. Now what's interesting is you would say, you're getting back to throttle too early, and I would agree... but... That pick up of the throttle is very much inline, if not slightly later than I have seen in other data. I think just a good spot to highlight the change in behavior in the car and the need to adapt the driver and the car. I want to be able to get back to throttle there but the cars response is to go into oversteer.
It looks u need to adjust your entry angle. The front engine cars start wider to the left and rotate the car with the trottle. U have so much front grip now the throttle input is causing the oversteer. Maybe u can double apex... this will allow u to open the wheel and get back into it and then lift for the second part of the turn? Not sure thats right but it looks like u can carry more speed by entering farther left as u have more front end grip to spare.
You and some others are telling me to hang it further left on entry there...most do. I need to be disciplined to try it. I do it for a lap or 2 and then habit takes over, it was not the fastest way for ME around that corner last year.
U know how to do it, first session is a throw away anyways just hang the car out there to the left and get used to it. Let the oversteer work for u and turn the car into the corner. I expect big things
