On the install “width” are you talking about how the two mufflers are connected together (straight pipe and exhaust tips) that gave you trouble?
Exactly. Make sure you measure in a few places and get the new mufflers set up exactly before you try to install them. I couldn't adjust mine once I got them under the car.

Last night I made up a set of dummy brake pad connectors, installed Porterfield R4 front and R4S rear brake pads, and mounted my Hankook RS-4 track tires (245/40/18F-275/40/18R). I was able to get it all done in about an hour.

I'm heading to Laguna Seca tomorrow. It will be my second track day in this car and the first with decent tires.

Saturday was a blast. It was a 103dB day so there were a lot of big money guys there. The guy next to me had a McClaren Senna AND a Lamborghini Huracán STO. There were huge tractor trailer rigs everywhere. I was definitely a small fish in a pool full of sharks. LOL!

I ran in Point By A (Fast). There was a group of guys running GT3s in our group and they were all running slicks. I'm usually one of the faster guys in Point By. Not this time. I was consistently in the bottom 3 out of 20-25 cars. I did have a lot of fun chasing a guy in an Elise and another guy with a GR86. Both of them were on 100TW tires. The Elise had a huge aftermarket diffuser. The GR86 had 235/40/18s and camber mods. I consistently pulled the Elise in the corners but he killed me on the straights. I would pull the GR86 on the straights but he would reel me in on the corners. It was fun.

The R4/R4S brake pad combo worked out well. I got to the point that I could threshold brake and feel the fronts breaking loose occasionally but the car never went into Ice Mode. Yeah!

The Hankook RS-4 were better than the Michelin PSS, but not by much. My best lap was only 1.3 seconds better than the last day out. I ran the tires at 31PSI F/R and they seemed to be happy there. The temperatures were within 10 degrees from inside to outside. I tried adding a couple PSI for the last session and it made the car more difficult to drive. I really need to get some camber on the car. I'm only getting 1.0-1.1g in the corners.

Looking at the data my best GTI lap had 3-7mph on the Cayman at every point on the track. I was able to brake later and carry more speed in the corners. The GTI was able to consistently pull about .2G more in every corner.

RaceChrono crashed mid session once and didn't record any data for the last session. I really need to look for a better solution.

Yes, it was. I've run with them 6-7 times in the last couple years.
Small world. I was 1 of the owner of ncrc for many years and sold it to Evan and Andrew a couple of years ago
I still Go to all the events and help them with instructions, drivers meeting, etc
Come to say hi next time you come to 1 of our events
I have 08 Cayman s but track a silver Mustang, usually in open

Small world indeed. I think I've seen you there. I think I even waved you into your parking spot near the garage at one point on Saturday.

The one upgrade I really want to do on my car is install the GT3 adjustable lower control arms so I can put a decent alignment on it. I looked for a couple months but couldn't find the OEM arms in stock anywhere. I finally gave up and ordered a Cup-Series Control Arm Kit (GT3 Rubber Spec) from Tarett Engineering today.

On you next brake pad swap you might want to consider Ferodo 3:12 pads, much better bite and they last about 3 times as long as street pads, I have also seen a difference switching from Motul brake fluid to Endless, much better pedal feel with Endless.

I have today and tomorrow off for company holidays so I decided to take a drive down Hwy 25 to Priest Valley. It's very dry, brown and not very pretty right now. The road itself long and windy and the kind of road that the Cayman was made for. The 4 mile stretch of Hwy 198 East of the 25 junction happens to be Motor Trend's test route for their annual Best Driver's Car competition.

Apparently it was let's see who can get closest to getting hit by Chris' car day. I had two coyotes and about 47 squirrels run across the road right in front of me. I also ran into something you don't see in Northern California very often. Roadrunners! How appropriate.


Look! That's my sign!

It was a good drive. I wish I had taken the time to drive a couple sections more than once. I also wish I had taken a couple shots of the car in scenic places. It was a dry dusty day though and honestly it wasn't very scenic.

I've found that just like in the cartoons roadrunners seem to be smarter than coyotes. The roadrunners were near the road but didn't approach it. When I stopped they kept a respectful distance. The coyotes seemed to have a death wish yesterday. I'm surprised that I didn't find any fur on the car when I got home. :rolleyes:

I didn't see any tunnels, bird seed or ACME crates anywhere. ;)

I've done that route (eventually ending up in Santa Cruz or Monterey) on my motorcycle when CA-1 was fogged in.. in the spring it's a bit more green and not dusty, nice road, mostly excellent road surface and no traffic except in Hollister (stopped for lunch there, sort of by accident in the bar made famous in the Wild Ones.. I only realized what the bar was when I came out and saw:

I'd rather have been on PCH (CA-1), but this route wasn't without its charms.. mostly the no traffic part of it. I've been stuck a number of times on CA-1 behind a terrified old man navigating a giant motor home around the curves at 10MPH...

The Tarett lower control arms showed up yesterday. I spent this morning getting them installed. It went pretty smooth and took about three hours.

I added 16mm to the arms and according to my digital angle finder I wound up with -2.4/-2.6 degrees of camber. I was shooting for -2.5. There's plenty of adjustment available in both directions so it should be easy to dial in.

I took a WAG and turned the tie rods out 8 full turns (1 turn per 2mm of shim). That seems to be about right. I wound up with 1/4" of total toe in. The steering feels a lot lighter. I think it had a lot of toe in before.

I'm going to get it an alignment done this week. I'm shooting for -2.5F/-2.0R camber and 0.0F/-0.3R total toe in.

For future reference the arms were installed at 60,500 miles.
