Ran a couple of events over the last two weeks trying to further dial in the suspension. At this point I'm relatively happy with the damping, but it feels like I still can't put the power down the way I want to, but trying to determine how much of it is just due to the old roached tires I have on the car right now vs suspension tuning. Picking up some fresh rubber for the July event hopefully.

Porsche event was on a mixture of brand new asphalt and old asphalt so broken and busted that there's grass growing through the sweeper. Normally this is the parking lot we park in while we race on the other much larger portion of the lot. Unfortunately the semi-truck car show was supposed to fully clear out Saturday night, but Sunday morning we showed up to a number of vehicles still parked right were where usually start and finish. After a last minute scramble to setup a new course we ended up with a tight winding course that definitely didn't favor big hp. There were only two cars over 400hp in the top 10 (Cayman GT4 and a 992 911 GTS).

Finished 5th in class (non-Porsche modified), but 11th overall.
Porsche Club June 2nd - Run 12 out of 10 (2 re-runs on the day due to spins)


Brought the car back to the house after that event and put it up in the air to nut and bolt it from top to bottom and then ran back through all my adjustments. I was apparently a complete mess the day of the Porsche event (forgot my tire pressure gauge and my helmet) and I had apparently backed the rear rebound all the way down to 1 out of 18 and had the compression up at 7. Changed everything back to how it was from two events before, then backed compression off 2 clicks front and 5 rear. At the SCCA event I ended up going up 1 click in the rear and up 1 in the front and the car felt pretty good. Good enough for me to win CAMC by over half a second for the first time in a while. This put me in 13th overall on raw times and 15th overall on PAX. Given the competition and multiple former national champions in our region I wasn't too upset by this result, but I know that with tires that weren't a season and a half old I could have found even more time out there, especially since I was 8th overall raw time after the first 3 runs and then coned away or overdrove my last 3 runs with the tires smoking hot.

The good news is that with a little rain in the morning only the top end of the CAMC field came out to play and with many of us making recent upgrades we finished the day with only 1.1 seconds between 1st and 4th in our class, next year we're going to combine with the one lone driver in CAMS for a paxed CAM class among us and he only beat me by 0.030 on PAX this weekend.

Finished 1st CAMC - 13th Raw - 15th PAX
SCCA June 9th - Run 3

It's been a while since I've updated this post as I've been busy and fighting the car a bit.

We ran a "night event" in July that was very different. Whole different challenge. Unfortunately the car was an absolute handful during the event and was fighting the rear end all over the place.

Due to some shifting in our schedule the next event was supposed to be the following weekend and I had to pull out of that event due to the car feeling very weird. at the rear, bordering on dangerous to drive. I didn't have my usual time to to a nut and bolt check on the car between events like I usually would and upon getting back to the house safely I found the inner of the rears corded and one of the rear camber arms coming loose. Sent the car back for a re-alignment and took a little toe out of the front as it felt overly "pointy" at turn in which was sort of throwing the rear out for me to catch.

I also took this time to go ahead and secure some new Bridgestones for the car. Finally ran a new event with the rear suspension actually tight and a little less toe-out up front. with nothing more than about 60 miles of driving on the tires, I proceeded to lay down some absolute heaters and finished 4th raw and 4th in PAX at the event. We did have a few people missing from this event, and the tight turns in a few spots allowed the V8's to really shine at this event against the typical miata crew. Still lost to two Miatas, but a national champ in a slick shod tin can and another tin can Miata with aero and boost are just going to be tough to beat no matter what.

Overall car felt much better and I am glad I drove the car with new tires before I pulled the trigger on spring rates. I still intend to change in the offseason, but this has shifted me to favoring a slightly higher rear rate than I'd initially.

Apologies for the video, but had to use the internal helmet attachment as it appears that my either my GoPro input or the external mic adapter died and the audio outside of the car is pure trash.

Had a cold but great event on Sunday but Sadly forgot the Go-Pro at home.



Course was a fast layout, but more of a high speed maintenance course vs an acceleration course. With the cold temps (50's feeling like upper 40's with the wind) the first few runs were tricky to get any grip at all. By the 5th run I was in a good spot within my class and decided to just send it. I really wish I had video as this run felt like the entire run was at 101% of what the car was capable of. In the end we dropped over a second on an already class leading time.



In the end I managed to finish 4th in PAX and 6th overall on raw times. First place was third at nationals, 2nd place won his class at nationals and third place is another former national champion. By far my best finish in this car and I owe it all to the MCS coilovers and the new Bridgestone tires on the car that were only on their second event. Also had the opportunity to meet and compete against Pete Bruschi and his CAMC Ecoboost who ran in Pro class so not to mess up anyone's regional championship competition. Unfortunately his well worn Yokohamas held him back on this cold day.

That school bus transport rig!!!!! 😆 🤔

Nice run Kyle. Must feel good to have the suspension really dialed in.
I know I saw it and want one so bad
 
I've always wondered if a Boss could fit into a school bus. I think it'd be cool to have the back half for car hauling, and set up the front half as an RV.

Now I'm wondering what top cruising speed would be (maybe add a Gear Vendors O/D), and what kind of fuel mileage it gets. Mileage can't be great, but can it beat a pickup and open trailer?

Those ramps look super-sketchy, though, and I'm not sure the approach angle would even work for a Laguna Seca splitter. What if you added an elevator lift like the big auto haulers have?

The hardest part was unlearning all the ways I learned to drive the car in the past. This result shows that there's speed in the sauce, I just have to cook it properly.

The transporter is super cool and a nice all in one rig. I'd be very tempted to put some more time into the "living space" within the bus, but I think that's going to come with time for him. I will say that the ramps sketch me out a bit and I'd want something more firmly attached in places and the approach angle would never work for my car as it's currently configured. I'd almost need a quick disconnect front bumper setup to get in and out.
 
When I started in racing in about 1988 with no money I bought a small old school bus that was going out of service.
Took most of the seats out and threw all the tools and tires in there. It towed the race car and trailer like a champ.
Drank a pile of gas, and oil, but it had lots of room, could even use it as a camper when we took the seats out.
Sure wasn't pretty, but it worked and never left us stranded on the side of the road!
 
First event was a rainy mess, took 4 clicks of compression out of the front and rear to try and get the car to get some bite, and it sort of worked. This year our region combined CAM into one PAX index class as we didn't have more than 3 or 4 consistent CAMC cars and only 1 or 2 random CAMS/T cars ever showing up. Luckily driving clean saved me from my buddy Juan and his Z06 as he had me on raw time and index time, but picked up a cone on his fastest run.

With the changing conditions throughout the day we were forced to run in the 3rd and potentially wettest and slowest conditions. I was shocked at how much speed we had in some areas, but ultimately was only good enough for 18th overall on raw times with other slower cars running in conditions that were dry enough to actually generate tire squeal giving them a massive advantage. In normal events Juan, Brent, and myself are all capable of top 10 times with all 3 of us dipping into the top 5 depending on layout.

Only offseason mods were some Steeda IRS bushing lockouts. Would love to say I felt them this weekend, but with the IRS braces and locating dowels already on the car I can't say I could feel any impact yet given the low grip scenario.

AMP is only 11 miles from my house while Road Atlanta is about a 45 minute scenic drive. Both great tracks and eventually hoping to get my car on both of them.
I read page 1 and page 13. I will read the other 11 pages, I promise, but until then, did you ever make it to either track with this car in the intervening 6 years? I live in Georgia, too, so I am just curious. I
 
I've run two events since my last update. First event was my first ever Pro-Solo where I was in P2 after the morning runs on Saturday and then the car just never went faster and I couldn't put down clean cone-free runs. When I got home I gave the car a once-over and found that the front driver's side swaybar endlink had backed off and disconnected. I assume I ran all or most of the event without the front swaybar which is why it was driving so poorly.

I was able to fix the endlink and moved the front bar to a 2/3 split to go a little stiffer up front to try and keep the car responsive and maybe transition in a little corner exit understeer without having to make a rear bar change. Showed up to the event and found a very very fast course. In the end I was hitting my 9,000rpm rev limiter in 2nd gear and with my tires that's pushing around 84mph. Car handled much better and the overall pax results show how much of a big aero/big tire/big power course this really was. Finishing 3rd on PAX and racing 1st heat before the course got cleaned up and rubbered in shows the potential in the car when it's not partially disassembled. Only 2 Miata's in the top 10 and one of those was last year's national champion in CSP.
