Well, this weekend was mostly free and the alignment place had some open time slots, so installing the JRZ RS One was a go. I just had to drive down to SoCal to do so.

Friday: The install went pretty smoothly. Everything went in as it should, including having the keys in the front struts to keep the strut from rotating inside the front axle spindle (coughcoughASTcough).

The only issue was the front spring was a bit short. I transferred over my 6" springs from my AST setup and threw on helper springs, but I really need some 7" springs for more adjustment range. I haven't taken any measurements but it sits a good 1/2" lower than before.

Saturday, I stopped by Robert at Chewerks to get corner balanced and an alignment.

The car weights 3397 lbs with ~3/4 tank of gas.

Corner balanced with me in the car (I could lose a few pounds :lol.

Also, my friend had sold his E46 M3 and had some parts left over. I made out with some nice loot, including a set of ACS pedals and this brand new Turner aluminum undertray.

I also traded my 2 OE front wheels for his 2 rear OE wheels, which made a square set for my friend with a E46 325i and a square set for me.

Our friend got a set of square wheels, I got a set of square wheels, and my friend gets stuff cleared out of his storage unit. Sounds like a win for all of us this weekend.

I gave the RS Ones a good street test after installing them: driving back up north on the I-5.

There are some gnarly stretches of highway, heavily scarred and rutted by big rigs and cracked from sitting in hot summer sun.

When I installed the RS Ones, I set them to JRZ's recommended street setting of 5 clicks from full soft and left them there for this drive.

Compared to my ASTs I had on previously, the RS Ones seem to take the "edge" off the impacts. Since I did not change the spring rates, the stiffness feels the same as it did before.

I haven't tried softening up the dampers any more but I will give it a try today on my way back home from work.

The next big test is trying them out on Mt. Hamilton up here in the South Bay Area. That will be really rough road to test out these dampers.

Dusted off and vacuumed the interior, and cleaned up the micro-suede steering wheel using Sonax's micro-suede cleaning product. Came out looking much better (and smelling good too). There were a few patches of matted fabric before cleaning. I got this wheel used from a friend but I imagine it looks like this when new.

Also, put on a few final touches on the JRZ installation.

Inertia Lab threw in these spring covers for free as part of the package. For a daily driven car, hopefully these will extend the service life of the dampers, protecting the shaft and shaft seals from road debris.

Also crawled under the rear to take off some of the pre-load in the LCA bushing. I don't remember if it was done after the alignment but I figured I would do it myself to be sure.

Also gave me a chance to admire the view.

Great journal so far! You've done all the right mods and Matt at TechCraftPerf really knows his stuff. He's helped me out plenty of times with my M3.

Thanks Tony! Matt has been a great resource and mechanic for my M3. I've been meaning to ask him about doing my wheel bearings. If only he were closer or I had more time during my short trips down there.
