    Thanks for the kind words! I am glad to see some activity on the forums again, and that people are enjoying the updates. I plan to stay up to date and should have a new update on both cars within the next few weeks.

    I haven't really gotten plugged into the car community in Charlotte yet, just the NASA racing crew at the events I've been doing. There seems to be a pretty large E30 community in Charlotte and in NC at large.

    Garage setup = goals. Can't wait to be able to custom make a setup like yours. Wish I knew you were in Charlotte, I was working there most of the year last year and would have loved to grab a beer.

    Car is great too of course, and congrats on the new pickup. Lots of respect for all the R3V'ers who competitively race their cars, tons of work and commitment but looks like a blast.

    I actually have a couple sets of nice 16" wheels, but tires are more of the problem. There are very few choices for DOT slicks in 16" sizes (see comments above about diameter). There are plenty of choices in 15" and 17", though. Looks wise I have always thought 16" is the best for E30s. Perfect compromise of wheel size, brake clearance, and tire sidewall.

    If I had larger brakes I wouldn't have really minded staying at 17", but without needing the brake clearance, I think it was worth removing the roll center spacers. The 15" wheels seem to be a net positive in ride quality, handling, and acceleration due to their decreased mass. The tires are a good $300-400 a set cheaper, too. That's not the end all be all for me, but I can't say as though it isn't nice when they are only competitive for 2 weekends.

    So far that's the goal, still got a few things I want to do to my car. Staying on tail of the dragon Wednesday night and up blue ridge Thursday. always a good trip. Cant wait to get away.

    2350 is pretty solid. Like you said there's more you could do. Bet its pretty fun on track!

    Well, you are kind of reading it right. Corner balancing has to be done at full weight, i.e. with actual fuel levels and the driver in the car (gear and all, preferably). Since I weigh just under 200lbs, the car weighs about 2,350-ish (as I did mention above).

    Car still has a full size battery, full glass, power windows, door skins, a dash with a bunch of electronics, working locks, all working latches/hinges. Still a lot of ways that it could potentially lose weight, but that I don't really care to do.

    I have been following along on Instagram and really enjoy the more detailed updates. I am loving the way this car looks with the 15s and you have me wanting to swap my 15x7 FFDs for 15x8s

    The car seems like it rips with the 170hp and the diff ratio you ended up with.
    Looking forward to what comes next!
    Thanks! With in reason, wider wheels are better. Even if you stay with the same tire size. The autocross bois have tested this a lot. 15x9" with a 225 is a common setup.

    And finally, some pictures from Roebling Road in March. These are the 15" wheels. Here's a link to in car video from this event again: https://vimeo.com/705917012

    To give you a sense of the power level/gearing for the car, I downshift from 5th to 4th in the braking for turn 1, and then leave the car in 4th for the entire lap. So those lower (not really low, this is a fast track) speed exits around 60mph are pulling from the middle of 4th gear. You can hear it really come on the cam around 4,600 RPM.

    Okay, I wasn't far behind. Only a few more photos from the car being up on the scales, and the current state of the grey car's interior.

    So the big update is I bought another car back in February. I check RacingJunk once in a while just for the hell of it. One day saw this E30 listed for a pretty good price, and I got really excited when I started reading about it. It was like the real race car version of my car. Quick list:
    • M52B28
    • E30 M3 5 lug w/ AST 4100s
    • IRP "DTM" style rear spherical trailing arms
    • Very nice FIA style cage
    • Tons of spare parts
    The price was fair, didn't even negotiate. It was a few hours away in Georgia, so I committed to it, and went to get it the following weekend. It came with so many spares I couldn't even fit them all on the trailer, in my X5, and inside the E30. It came with 4 extra medium case LSD's, 4 extra sets of wheels/tires, an extra composite hood, a brand new never used Bimmerworld V3 carbon fiber wing, ceramic coated Euro S50 headers, full 4 lug strut and trailing arm setup, consumables like pads, some maintenance parts, a bunch of new and used iS front lips and rear spoilers, and even more I can't recall. I was packed up to the gills, and couldn't fit the composite hood. A friend of mine picked it up in GA for me and brought it to our next race for me.

























    The next day when I unloaded everything, it was a bit of "oh crap, where is all this stuff going to go." After sorting through it, I posted some stuff for sale, and packed some stuff away that I knew I was going to want to keep.















    Cool center jack points that are integrated into the roll cage at the door bars. And the rear IRP spherical adjusters.








    Too many wheels... I've been dismounting shot tires and will need to clean up at least 3-4 of the sets to be sold.






    So prior to me purchasing the car, about 2 years ago, the PO had crashed the car at Road Atlanta during his first BMWCCA club race. The body was repaired and the car was repainted BMW Space Grey, which is actually the same color as my X5. The paint job and body work are pretty good. The passenger side rear quarter panel was replaced and the fender isn't rolled like the other side is, so I will definitely need to do that.

    The cage is super nice, one of my favorite parts of the car. It's just designed well, bars are all noded, the FIA style door bars are kicked out all the way to the outer door skins, triangle foot saver bars. All the goodies.

    The previous owner(s) were tall guys, so the dropped down the floor pan and made a cage setup for attaching the seat. They also cut out the tranny tunnel so the seat can be more centered. The steering column support was cutout and new mounts were made that attach to the roll cage dash bar. That centers and straightens out the steering column better than factory.

    The rest of the interior is meh. It didn't have a dash. The gauge cluster was attached to the dash bar and it was wayyy too high. I knew I'd want to add a dash to the car and clean up the interior a lot. I sold the passenger seat and harness. It took me a while to find a dash. I found a pretty rough one an hour away. Price was okay. It actually had minimal cracking, but it was soooo faded and nasty. After hosing it off and soaking it in 303 Aerospace protectant, I laughed to myself, because the dash cleaned up sooooo well. This is a dash people would swap out for on a nice street car. And I cut the crap out of to fit it around the cage.

    My plan for this car is to fix it up some, get it sorted/straightened out, and then do "comp school" with it later this year to get my racing license. It will be a TT5/ST5 car, like my black car, but probably a lot more competitive.

    After cleaning up and reorganizing the garage (thank God for the lockers/cabinets, etc.), I really wanted to mount of the Bimmerworld wing. I'm not sure if I will run it straight away, but long term I do want to run full aero on this car. The wing and a large, solid front splitter to match it. I will probably shake the car down without it, so I know what I'm starting with, before mixing in the aero. I don't have any experience with aero, so it will be a good learning process.


    They had previous put the stand offs on the trunk, and the trunk had holes for an iS spoiler. I had 4 iS spoilers that came with the car, so I knew I wanted to modify one of them to fit with the wing on the car as well. And I really wanted to see the wing on the car.











    One of the few interior shots I have... I didn't take many because it was so ugly with no dash and everything clamped to the dash bar.









    Zip tie grave yard after taking all the FIA padding off the passenger side. Still a lot of residue I have to clean up.






    The big ass Hoosiers fit this car easily, it has more camber due to the fully adjustable rear. I will have to roll the passenger side flat or maybe cut out the inner lip, though. The passenger side is touching. Plenty of clearance on the rolled/pulled driver side.









    Painted the spoiler and got the wing mounted up on the car.














    Ahhh here is the interior in all it's glory. This is actually after removing everything on the passenger side! There was more stuff up there on the dash bar, and another seat/passenger for a passenger... started working on the dash. Tried to be patient and cut only a little at a time. Since the A-pillar support bars that span from the door bar to the middle of the A-pillar bar are more narrow than the A-pillar bars themselves, the dash had to be cut even more narrow than normal to be able to fit in between those bars. I got it, eventually.













    The seat setup is neat. You cannot reach the bolts between the seat and the tranny tunnel, because there is no clearance to get a wrench on it. So with the frame they made for the seat mount, you just have to remove the nuts underneath the car and you can pull the whole seat and side mount setup out of the car easily. Pretty cool design. Fuel return and brake line go through the cabin, I am not sure why, probably because of the cut out floor pan and the center jack point. Too risky to keep them on the rocker side of the car, or you might pinch them jacking the car up. I'm only guessing at least. They are hard lines with no fittings in the car, so safe/legal, thankfully.













    Sorting out what was going on with the wiring. That is probably the weak point of this car. The wiring isn't very clean or well thought out. I've been fixing and repairing some of it, while trying to not go too crazy. Just making sure it's safe, and functional. There was an adder fuse box already for accessories, so that is kind of nice. I have electronics to add in, so I don't need to cut up any stock wiring to do so.







    Wangggggg







    Another side bar adventure back to FL! I had the chance to go down for 5 days to test the Spec E9X at Sebring for the first event of the year there. This is an ST5/TT5 car, so I had a chance to finally secure the TT5 track record! If you recall I had done the record in my E30, but crashed the same session, getting DQ'd in the process.

    Since the last time I had driven the E90, not much had been changed besides aligning and corner balancing it. Changed to a less aggressive front brake pad, but that's about it.












    It wouldn't be FL without an afternoon "hurricane" taking out all the tents in the paddock!












    Admittedly it was easier setting the record in this car than it was when I did it in my E30. I was able to get it by over 2 seconds in just my second session of the first day. Then I reset it again in the last session of the second day. Got down to a 2:31.7. Carlos did a 2:30.4 in the car in the race group. I know there is still a lot of time left in the car. It should be mid to high 2:20's after some more development.

    We were going to test the car back to back with new sticker Toyo RR versus new Maxxis RC-1 R2's, but after battling some brake rotor and ABS issues the first day, and a busy schedule all weekend, we decided against it.


    8 E30 tires versus 8 E90 tires:






    When I got home, I setup and leveled my scales so I could corner balance the black car again. It had been about 2 years since I'd done it, and in the mean time had changed the rear springs, alignment, and the weight of the car (its about 2,350lbs wet now). I expected it to be a bit off, but the balance was spot on. I mean, dead on. I didn't touch it. But at least the levelers are good to go for when I balance the grey car.











    That brings us current up to like 2 weeks ago. Have to upload some more photos now...
