That's some good numbers. Glad your car is back. Did you get your Ohlins back ? I run into an issue with my spring insulators on the front (will need to replace). Looking forward to your track days sounds like fun.

The Ohlins were the easiest part of this whole thing. They got them on a Friday, and I had them back the next Friday.

This is great support

Did you have any issues installing them in your rear? I have a 2017 Mustang GT as well, but I am worried I will need to dremel

I don’t know for sure because I had a shop do them. But I don’t think they did. @bnight might know. He has the same setup.

I did have to dremel the RLCA's the shop that installed them did it but it didn't do a great job about it. I think newer S550's namely Mach 1 RLCA's have the correct shape but I'm not sure the RLCA's fit. I have to ask a friend to give me one so I can test fit it and see.

Oh that would be perfect, perhaps I can order the part instead!

Sunday project: replace OEM rear upper shock mounts with Vorshlag's. I broke the left one a couple weeks ago at Road Atlanta. Drove around a bit after and it is silent and smooth.
And yeah, I see the split rubber on the spring.

Got some work done this month, in spite of all my friends trying to coerce me into trading her in for a Porsche.
Added:
APR splitter and rear wing
Mishimoto radiator and oil cooler
Vorshlag camber plates
SPL lower control arms
SPL tension rods




The best news is that, thanks to a phone call with Vorshlag I figured out why the 305’s wouldn’t clear the coil overs with more than 1 deg of camber: Quantum Speedworks installed the coilovers wrong. They weren’t supposed to have this upper spring seat spacer in there. @bnight pointed me in the right direction (thanks, H!)

I also think they (might have) provided the wrong Ground Control camber plates (probably provided something for OEM springs, not coilovers). So I am happy to finally get the Apex forged wheels on the car with 3.2 deg camber. I’m sure the SPL bits helped. I didn’t try fitting it without the SPL stuff. I thought those wheels were going to be paperweights in the corner of my garage. It just didn’t seem right that I’m the only Mustang guy who couldn’t get them to fit.

Next weekend I’ll put on the Whiteline end-links and Girodisc front rotors.

Lastly…and on a completely different note…for years I have had people tell me that I look like Will Farrell. While walking along at COTA this week during F1, I heard someone shout “hey, I got a job for you”. I looked over and it was this guy:

Not Will, but a pretty good impersonator. I turned down his offer of employment.

It's funny how we both want to do the exact same mods to our cars Also the uper spring seat i think I still have it with my Steeda camber plates but that's because Steeda camber plates are for OEM shocks/struts. if you have rear camber plates for coilovers like (Vorshlag) you can remove that as well as the annoying rubber spring insulator that Ford runs (mines are starting to make annoying noises).

I'm also looking into the Mishimoto kit for cooling as well as a similar aero package and Whiteline Endlinks. I went with different front and rear disks (Unitesta) but the idea is similar to the Girodisk setup also the 4 disks are 15 kg (33 lbs) total lighter than OEM so can't wait to see how this improve lap times.

Glad that your car is moving in the right direction I'm sure it will be even faster now. Keep us posted on how the cooling kit is helping your CHT temps.
