    It will be easier to stay up with the thread if I do it frequently, right?

    I forgot to post this last time. Quarantine has brought out my OCD (read: need for control), so I've been keeping the shop/warehouse more clean and organized than I usually do. It's my place of zen. Along those lines, I have been meaning to upgrade the tunes for quite a while. I've only ever had a small bluetooth speaker out there, and the bay is over 1,000sq/ft. If you were more than 12ft or so away from it, it would be too quiet. If you were close to it, especially using the computer, it was way too loud.

    After doing a little bit of research, I went with a popular but budget/entry level setup of a Yamaha R-S202 receiver and ELAC B6.2 bookshelf speakers. I placed the speakers about 20ft apart from each other upstairs in the loft, above the work area. It sounds FANTASTIC. The volume levels throughout the entire bay are much more consistent now. You never feel that it's too quiet or too loud no matter where you're working. It was well worth it and I wish I had done it sooner.






    With the E36 running and driving, I turned my attention back to the E30 this week. I've had an aluminum rear firewall/seat delete from Condor sitting around for a few months. Since I have my battery and fuel surge tank in the trunk, I've wanted for a long time to seal off the rear firewall better. Particularly the rear parcel shelf (directly above the surge tank) has a ton of large holes in it. At first I wanted to retain the 3rd brake light on the parcel shelf (you can never have enough brake light visibility), but I quickly realized that it would compromise the whole purpose of a sealed off firewall since there is a big hole under it for easy bulb replacement.

    The top portion of the shelf was pretty easy to install. I used 2 of the stock threaded holes, and then added M6 rivnuts for the rest of the holes. On the outer edges (places I couldn't get a drill or the rivet tool into), I lined the metal with some weather stripping so hopefully it does not rattle at all.








    The seat-back portion was a bit harder to setup, since you have to modify it as needed to clear your bar/cage. Since my cage builder did a good job of making patch panels that fit well around the down bars, I just cut the corners by the down bars out completely.










    It's fairly hard to get the parcel shelf portion in, but it was a really bar navigating the seat back portion in around the bar. The higher you get up in the car, the narrower it gets. I scratched the shit out of my passenger side rear quarter window glass the first time I put it in the car. Later on I figured out a good method to do it, but I definitely put a bunch of scratches on the roll bar and interior regardless.

    I did finally remove the last of the sound deadening in the car, which is just the portion that was above the fuel tank, where the seat bottom was. The entirety of that sound deadening weighs a whopping... 5lbs. My floor pans really need a new coat of paint, so I will paint the rear seat and the floor pans at the same time, probably this weekend.








    Everything fitted up, holes drilled for the rivnuts. Panels are set to be painted flat black, then final installation.

      Any reason for the parcel cover/rear seat or just cause? Plan to paint it?

        Both questions were answered in the text accompanying the post

        This is the main reason:

          Nice work! Awesome updates. The new wheels and tires give the car an awesome purposeful look (and I'm sure they perform well too!). Great pickup on the coilovers as well. Overall I love your super clean execution on all these mini projects. Always looking forward to the next update.

          Audio upgrades are definitely underappreciated until you do them. I just did the same change from bluetooth speaker to surround sound. WOW it really makes me happy.

            And we're back! I wrapped the some projects on the car in early June, as we were finally back to racing after over 4 months off. Let me tell you that racing in Florida in June, July, and August is brutal. After a couple years, the paint in my interior needed some re-coating in the high traffic areas. I've really loved the results when using Rustoleum enamel in a jar. Just roll it on with a 4" roller, and it's not messy, it's durable, and it looks nice and even. The only caveat is that it takes a while to fully dry, especially on any paint that goes over seam sealer (I'm not sure why that is).






            Painted the rear firewall sections.






            Started painting the cage and interior in the E36, which had seen better days.






            E30 after a day or two of drying:






            Got some cool old school Momo wheels for the E36.












            The interior of the E36 is mostly done, for now. Also installed some ducting and the stock plastic stuff around the radiator.








            Here is the final result with the rear firewall in the E30. Installed with black zinc screws and black finishing washers.







            I had been chasing an annoying clunk in the rear end of the E30 for quite a while. I had bolt checked the car 3 times (which actually probably fixed several other minor rattles, like the rear exhaust heat shielding) and hadn't come up with anything. On a whim I replaced the RSM's with Rogue Engineering units that still have rubber bushings, and that fixed the problem. Even though my spherical RSMs had no discernible play in them (in fact they were quite tight), they were rattling just enough to make a racket since my car is fully gutted.






            One of the last things was getting the car aligned before the event. It didn't need much adjustment, but I really wanted to see where my camber was at after going back to stock-height rear subframe bushings.






            Washed it and loaded it up a few nights before the event, so leaving after work would be easier.














            The event at Sebring went well. I matched my personal best on the R888R's on Saturday, and then ran the Hoosiers with the new Bimmerworld wheels for the first time on Sunday. I did a best time by over 2 seconds after getting used to the slicks. Following my best lap I was showing almost another second of improvement, but pushing too hard, I went off in turn 16 (second to last corner at Sebring). Nothing bad, just a dirt drop on the outside that cost me the lap and my time from that session. I was still able to win TT5 on Sunday.

            Disconnected the rear sway bar on Sunday, and I really liked that change with the high spring rates that I'm running. It was fine with the bar connected with the R888R's, but I didn't like the feel of the bar with the Hoosiers. The rear driver's side tire was rubbing a little bit, but annoyingly it's on that bump on the INSIDE of late model fenders. I am going to try smashing down that bump before the next event.

















            One of my upcoming projects is going to be swapping in a new fuel tank. Surprisingly there is 0 rust inside mine, but in a previous life, someone jacked the car up by the tank. There is a huge dent on the passenger's side, near where the pump picks up from. I think I get even worse in-tank pump starvation than E30's normally get because of it. I don't get any cutting out because of the surge tank, but the in-tank pump is crying for it's life unless I run the tank full. We'll see if a new un-dented tank makes any difference there.






            Back to working on the E36 getting it ready for it's first event, I installed ISC N1 Track coilovers care of Bimmerworld. I had AST's on there, but they were all blown, and they are costly to repair (if parts are even available -- they were an old design). I sold them and just went something inexpensive but well proven. When I put the car back down, it was obvious by the front wheel placement that one of the sides had something going on. One wheel was centered, and one was pretty far forward in the fender. I wasn't sure which side was off since it's been a while since I've had an E36, and I knew M3's had different caster than non-M's, and that 95's were different than 96-99's. I checked the part numbers on the control arms and spindles first, and they were right for the car (this one is a '95). It wasn't obvious at first, but it turns out the passenger side control arm was bent (and the tie rod too). I knew this car had been crashed, hard, more than once. Guess these pieces never got replaced. The subframe and spindles look okay, so we'll see how it looks after I get the new control arms and tie rods in this week.











            I'll leave you with just a teaser now of one of the on-track photos. I have the whole set to post later, just don't have time at the moment.

              awesome stuff man! Love the new carbon fiber hood. Would you buy it again?

              Also, why can't you run 15's? E30 M3 brakes should clear no problem.

                Hey Eric. Overall I am happy with the hood, but it does not fit very well. It seems to me that all composite E30 hoods are high on the sides, in the center of the fenders. This one is a good 1/4" - 3/16" taller than the top of the fenders, even after a ton of time spent adjusting it as best as I could. My older VIS hood had the same issue, though not quite as bad.

                I have roll center spacers in the front that prevent 15's from fitting. The tie rods hit the barrel of the wheel. I've considered removing them, but I think it's a net positive running the larger wheels with the roll center spacers. Plus, for E30's, the only plausible Hoosier tire size is the 225/40-17 they make and I'm now running on the Bimmerworld forged wheels.

                  Yeah, that'd be interesting to see if no roll center spacers and smaller wheels feels better than roll center spacers + big wheels. Running a 225/45/15 R7 would be a hoot!

                    225/45-15 is too undersized though. I'm running a 4.10 diff, which is already borderline too short. I would like to try them back to back though. The weight being the advantage with the 15's.

                        My first real camera is 15 years old, a Canon Digital Rebel XT. I started keeping it in the shop so I'd start shooting again. Still have the lens I bought with it too, a Sigma 18-50 EX.

                          Awesome update, instagram is cool or whatever, but the forums fulfills like the E30

                          What engine trans mounts are you running?

                          did you cut 2 rocker shaft access holes in the fire wall yet? :)

                          What sway bars are you running?
